Your X431 Pro V5 is one of the hardest-working pieces of equipment in the shop. It boots before the first car rolls in, streams live data for hours, runs bi-directional tests, and gets shoved back into a case at the end of the day. Nobody thinks about the KPL944755-2S2P battery<\/strong> inside it \u2014 until the tablet dies mid-diagnosis with a customer standing next to you.<\/p>\n\n\n\n

The Replacement Battery KPL944755-2S2P 6300mAh for Launch X431 Pro V5<\/strong> is the part that restores the tablet’s original endurance. This guide covers how to recognise a worn-out cell, what to do when your Launch X431 Pro V5 won’t charge<\/strong>, how long the battery should actually last in different workshop scenarios, and how to make sure you buy the right one.<\/p>\n\n\n\n

What the KPL944755-2S2P Battery Actually Is<\/h2>\n\n\n\n

Before buying anything, confirm the specs match what is in your tablet.<\/p>\n\n\n\n

The KPL944755-2S2P is a lithium-ion pack rated at 7.6V and 6300mAh, equal to 47.88Wh<\/strong>. It uses a 2S2P cell configuration<\/strong> \u2014 two cells in series, which produces the 7.6V nominal output, with two of those series pairs in parallel, which is how the pack reaches 6300mAh. It is a black, internal pack certified to CE, RoHS and FCC<\/strong> standards and typically sold with a 12-month warranty<\/strong>.<\/p>\n\n\n\n

The Launch X431 Pro V5 ships with a 47.88Wh (7.6V, 6300mAh) battery from the factory \u2014 the same specification these replacement packs are built to meet. That is a reasonably large pack for an 8-inch Android tablet, and it is the reason the Pro V5 has a solid reputation for endurance compared to older X431 generations.<\/p>\n\n\n\n

Understanding the 2S2P configuration matters when you are comparing listings. A pack advertised as “6300mAh” but rated at 3.8V<\/strong> is a different battery entirely and will not work in the Pro V5. Always check the voltage alongside the capacity, not just the headline mAh figure.<\/p>\n\n\n\n

One Critical Compatibility Note<\/h3>\n\n\n\n

Nearly every seller carries the same warning, and it is the most common cause of a wasted order: this battery is not compatible with the 10-pin, 9-line version of the tablet.<\/strong><\/p>\n\n\n\n

Launch shipped the X431 platform with more than one battery connector layout across revisions. If your tablet uses the 10-pin \/ 9-line connector, the KPL944755-2S2P is the wrong part. Open the tablet and check the connector before ordering \u2014 count the pins, compare the shape, and verify the part number printed on your original battery label matches.<\/p>\n\n\n\n

Why Your X431 Pro V5 Battery Wears Out<\/h2>\n\n\n\n

Lithium-ion batteries are consumables. Every charge and discharge cycle consumes a small amount of the cell’s usable capacity, permanently. Good quality packs like this one are rated for over 500 charge\/discharge cycles<\/strong> \u2014 which sounds like a lot until you consider how a diagnostic tablet is actually used.<\/p>\n\n\n\n

A diagnostic tablet is close to a worst-case application. It draws heavy, sustained current during live data streams, bi-directional actuator tests and module coding \u2014 far more than browsing or email. The display stays on for the entire diagnostic session, often at high brightness in a bright workshop or outdoors. Heat builds up from tablets left on a dash, in a hot vehicle cabin, or running continuously in summer, and heat is what accelerates chemical ageing fastest. Bluetooth and Wi-Fi are always active, because the DBScar VII VCI communicates wirelessly and software updates and remote diagnosis run over Wi-Fi. And charging habits are irregular: shop tablets get charged whenever someone remembers, which means frequent partial charges, long spells at 100% on the bench, and occasional deep discharges overnight.<\/p>\n\n\n\n

The result is fairly predictable decline. In the first 12 months<\/strong>, expect 100% down to about 93% capacity \u2014 still a full day of diagnosis with overnight charging only. By one to two years<\/strong>, you are at roughly 92\u201385% and may need an occasional midday top-up. At two to three years<\/strong>, capacity typically falls to between 84% and 70%, and you are charging between jobs and hunting for the charger. Beyond three years<\/strong>, most packs are below 70%, dying mid-job and sometimes starting to swell.<\/p>\n\n\n\n

For a high-volume shop, expect to replace the battery somewhere in the two-to-three-year<\/strong> window. Shops that run the tablet hard all day, every day, may be closer to 18 months.<\/p>\n\n\n\n

Signs Your KPL944755-2S2P Battery Is Failing<\/h2>\n\n\n\n

Do not rely on a single symptom. Worn-out cells usually give you several warnings before they become unusable.<\/p>\n\n\n\n

Runtime has dropped significantly.<\/strong> If the tablet used to run most of a shift and now needs charging after two hours of diagnostics, the capacity is gone. This is the single clearest sign.<\/p>\n\n\n\n

Unexpected shutdowns with charge showing.<\/strong> The battery reads 30% and the tablet powers off mid-scan. This is classic behaviour for a worn cell that can no longer deliver peak current under load \u2014 the X431 draws its heaviest current during module coding and actuator tests, which is exactly when the tablet dies. This symptom often appears before<\/strong> capacity loss becomes obvious, because a cell can hold charge but not deliver it.<\/p>\n\n\n\n

The percentage is unreliable.<\/strong> It drops from 60% to 20% in minutes, or jumps upward when you plug in. The battery management system can no longer track the cell’s true state.<\/p>\n\n\n\n

Charging behaviour becomes erratic.<\/strong> Charging stops partway, restarts, finishes suspiciously fast, or the tablet reports charging while the percentage never moves.<\/p>\n\n\n\n

Heat during normal use.<\/strong> A battery that gets noticeably warm during light diagnostic work is working harder than it should, and heat accelerates its own decline. Combined with a warm workshop or a tablet left in a vehicle, this becomes a downward spiral.<\/p>\n\n\n\n

Physical swelling.<\/strong> The screen lifts from the frame, the back cover bulges, or the tablet no longer sits flat. See the safety section below \u2014 this one changes the urgency considerably.<\/p>\n\n\n\n

The performance symptom nobody expects<\/h3>\n\n\n\n

A degraded battery can make the X431 Pro V5 feel slow<\/strong>. Power management on Android tablets can reduce CPU clock speeds and throttle background tasks when the battery is weak or the voltage sags under load. Technicians often blame Android 10, a software update, or a failing VCI when the tablet is actually responding to an ageing cell. If your Pro V5 became sluggish and the battery is three years old, replace the battery before you spend money on anything else.<\/p>\n\n\n\n

How to Actually Test the Battery<\/h3>\n\n\n\n

The X431 Pro V5 does not offer a detailed battery health screen the way a phone does, so you have to test it in behaviour.<\/p>\n\n\n\n

Charge it to 100% and note the time. Take it off the charger and time a normal diagnostic session \u2014 live data on one vehicle, steady screen-on, Bluetooth VCI connected \u2014 then record how long it lasts and compare against the expected runtime figures below. Under half the expected figure means the pack is done.<\/p>\n\n\n\n

Then watch for a voltage sag shutdown<\/strong>. If the tablet dies during a heavy operation like bi-directional testing or coding while still reporting meaningful charge, that confirms the cell cannot deliver current. Check the reported percentage at the moment of shutdown: if it consistently dies between 20% and 40%, internal resistance has risen and the pack is worn.<\/p>\n\n\n\n

This is a better test than any number on a screen, because it reflects the way you actually use the tool.<\/p>\n\n\n\n

Battery Won’t Charge? Diagnose Before You Buy<\/h2>\n\n\n\n

A Launch X431 Pro V5 battery not charging<\/strong> does not automatically mean the battery is dead. The battery is only one of several possible causes, and replacing a good battery solves nothing. Work through these in order.<\/p>\n\n\n\n

Check the charger and cable first<\/h3>\n\n\n\n

Test with a different adapter and a different USB cable. The Pro V5 charges over USB, and cables fail far more often than batteries do \u2014 internal breaks in a cable are usually invisible from outside. Use a quality adapter with adequate current output; a weak or low-quality charger can cause a tablet to charge extremely slowly or not at all under load. Charge with the tablet powered off to see whether it accepts charge at all.<\/p>\n\n\n\n

Inspect the charge port<\/h3>\n\n\n\n

The Type-C port on a shop tablet takes a beating: dust, metal debris, workshop grit, and repeated plugging. Look inside it with a light for a compressed layer of debris blocking the contacts, then clean it gently with a dry, soft brush or a wooden toothpick. Do not use metal tools.<\/strong> Test whether the cable now seats firmly, and check for a loose port or damaged connector that would need replacement.<\/p>\n\n\n\n

Consider the load while charging<\/h3>\n\n\n\n

A diagnostic tablet under load can consume more current than a marginal charger supplies. If the tablet holds its level when idle but drains slowly while plugged in during heavy diagnostic work, the issue is charger capacity rather than the battery. Move to a higher-output adapter.<\/p>\n\n\n\n

Rule out software<\/h3>\n\n\n\n

Occasionally the tablet stops correctly registering the charger. A full power cycle \u2014 hold the power button until it shuts down completely, then restart \u2014 resolves this more often than people expect. Check for system updates, and if the tablet is badly misbehaving, a factory reset (after backing up diagnostic reports) may help.<\/p>\n\n\n\n

Check the temperature<\/h3>\n\n\n\n

Lithium-ion packs refuse to charge when cold. A tablet left in a vehicle overnight in winter will not accept charge until it warms up. Conversely, a tablet that has been running hot all afternoon may pause charging until it cools. Bring it to room temperature, and let it cool down before charging after a long session.<\/p>\n\n\n\n

Reseat the internal connector<\/h3>\n\n\n\n

If the tablet does not recognise the battery at all \u2014 no percentage, instant shutdown when unplugged, or a battery icon error \u2014 the internal connector may simply be seated poorly. Reopening the tablet and reseating the battery connector is a legitimate first step. Check that the connector pins are clean and the copper contacts are fully exposed, with no debris or corrosion.<\/p>\n\n\n\n

Suspect the battery itself<\/h3>\n\n\n\n

If you have eliminated everything above and the tablet still will not charge or hold charge, the pack is very likely at fault \u2014 particularly if it is more than two years old, if it has ever been deeply discharged and left stored, or if it shows physical signs of wear.<\/p>\n\n\n\n

How Long Should the KPL944755-2S2P Last? Real Usage Scenarios<\/h2>\n\n\n\n

Expected runtime depends almost entirely on what you are doing. Published figures for this tablet range from around 10 hours<\/strong> of continuous use in typical conditions up to 15+ hours<\/strong> of lighter work. Here is what that looks like in practice.<\/p>\n\n\n\n

The mobile technician<\/h3>\n\n\n\n

Driving between jobs, tablet running on battery all day, Bluetooth VCI connected, intermittent diagnostics, display on and off. A healthy pack delivers 8\u201310 hours<\/strong> of working time, comfortably covering a full day of appointments with overnight charging. A worn pack gives you 3\u20134 hours<\/strong>, and the technician ends up charging from a vehicle USB socket between jobs or carrying a power bank.<\/p>\n\n\n\n

This is the profile that exposes a dying battery fastest, because there is no opportunity to top up mid-task. If you are mobile, runtime is the whole point of the tool.<\/p>\n\n\n\n

The busy shop bay<\/h3>\n\n\n\n

Tablet on a bench, plugged in between vehicles, heavy live-data streaming and bi-directional tests. A healthy pack covers a full day even with heavy testing, with the charger available as backup. A worn pack dies during a long diagnostic session.<\/p>\n\n\n\n

Nothing is more disruptive than losing a live data capture or a coding session halfway through because the tablet shut down. On some vehicles, an interrupted module coding procedure can leave the module in an unhappy state \u2014 a genuinely expensive consequence of a cheap battery.<\/p>\n\n\n\n

The roadside diagnostic call<\/h3>\n\n\n\n

Remote or roadside service, no mains power, high-brightness screen in daylight, possibly cold weather. A healthy pack manages 4\u20136 hours<\/strong> of continuous heavy diagnostic work. A worn pack gives you under two hours, with shutdown risk at low temperatures.<\/p>\n\n\n\n

Cold is the worst enemy of an ageing cell \u2014 a pack that behaves acceptably in a heated workshop can fail outdoors in winter. If your work involves roadside calls, battery condition is not a convenience issue, it is a reliability issue.<\/p>\n\n\n\n

Flashing, coding and programming<\/h3>\n\n\n\n

ECU programming, module replacement and long coding operations are the heaviest sustained workload the tablet runs. Even a healthy pack faces a real load here, and a worn pack carries high risk. Programming operations need stable power over an extended period and draw sustained high current, so a weak cell can cause voltage sag that interrupts the operation.<\/p>\n\n\n\n

Always have the tablet on mains power during programming work.<\/strong> This is good practice regardless of battery condition, and essential on an older pack.<\/p>\n\n\n\n

The bench tablet<\/h3>\n\n\n\n

If the tablet stays in the case, used for occasional quick checks and mostly on the charger, battery condition barely matters \u2014 but watch for damage from chronic 100% storage<\/strong>. A tablet left permanently on charge at high temperature ages its battery faster than one that cycles. If the tablet lives on the bench, consider unplugging it once charged.<\/p>\n\n\n\n

Choosing the Right Replacement Battery<\/h2>\n\n\n\n

Not all listings for the KPL944755-2S2P are equal. Check these before you buy.<\/p>\n\n\n\n

Verify the part number and connector.<\/strong> Match the part number printed on your original battery label to KPL944755-2S2P exactly. Some listings also reference KPL9447552S2P<\/strong> without the hyphen, which is the same part number written differently. Then confirm the connector \u2014 this battery is not compatible with the 10-pin, 9-line version of the tablet.<\/p>\n\n\n\n

Check all three ratings.<\/strong> Voltage, capacity and form factor all have to match: 7.6V<\/strong> (a 3.7V or 11.1V pack will not work), 6300mAh \/ 47.88Wh<\/strong> (lower capacity means shorter runtime), and physical dimensions with the connector in the matching position. Ask the seller for dimensions if they are not listed, and compare the product images against your old battery.<\/p>\n\n\n\n

Look for certifications and cell grade.<\/strong> A legitimate replacement should carry CE, RoHS and FCC<\/strong> certification. Look for listings that specify Grade A cells<\/strong> and describe their protection circuitry. A proper pack includes overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection and thermal protection. These are not marketing features \u2014 they are what stands between a workshop mistake and a fire, and they are exactly what is missing from the cheapest unbranded packs.<\/p>\n\n\n\n

Confirm the warranty.<\/strong> Reputable sellers offer 12 months<\/strong> on this battery, some up to 24 months. Be aware that normal capacity loss over time is not a warranty defect \u2014 batteries are consumables, and the warranty covers premature failure and manufacturing faults, not the gradual ageing every lithium-ion pack experiences.<\/p>\n\n\n\n

On price, budget online listings run around US40\u2013<\/code>45<\/strong>, mainstream battery retailers typically US55\u2013<\/code>65<\/strong>, and official Launch service parts are higher and usually quote-based. The $40 band is not automatically bad, but be more careful: check reviews, confirm the certifications, and make sure the seller honours the warranty. A pack that fails after eight months is no bargain at any price.<\/p>\n\n\n\n

Replacing the Battery: What the Job Involves<\/h2>\n\n\n\n

The KPL944755-2S2P is an internal pack. This is a moderate DIY job for someone already comfortable working on electronics with the right tools, but it is more involved than swapping a battery in a device with a removable one.<\/p>\n\n\n\n

Before you start, back up everything \u2014 diagnostic reports, saved vehicle records, custom settings. Never open a shop tablet without a backup. Power the tablet off completely and unplug the charger. Work on a clean, static-safe surface away from metal debris, screws and loose tools. And photograph each step as you disassemble, especially the connector orientation and screw positions, because reassembly is where mistakes happen.<\/p>\n\n\n\n

The general procedure is to power down and discharge the battery where practical, since a discharged cell is less hazardous to handle. Remove the rear housing or screen assembly to expose the battery, following the correct order for your revision. Disconnect the battery connector first<\/strong>, before any other internal work, to prevent accidental shorts. Remove the retaining screws and the battery \u2014 the pack may be held with adhesive, in which case heat and gentle, patient persuasion are needed, and you should never pry aggressively. Install the new pack, reconnect the connector properly, and reassemble in reverse order. Charge fully before the first diagnostic use.<\/p>\n\n\n\n

If any of this is unfamiliar, or if the old battery is swollen, stop and use a professional. The labour cost is minor compared with the cost of a damaged board or a damaged tablet.<\/p>\n\n\n\n

First-use charging<\/h3>\n\n\n\n

A new pack normally ships partially charged. There is a persistent myth that lithium-ion batteries need a 12-hour first charge \u2014 they do not, because they have no memory effect. What actually helps: charge it fully before first use, then run it down and recharge normally for the first few cycles so the tablet learns the pack’s real capacity. Avoid deep discharge in normal use and charge at around 10\u201320% remaining. If the tablet stops charging partway on the first charge, unplug, reconnect, and continue \u2014 this is normal with a fresh pack as the charge controller calibrates.<\/p>\n\n\n\n

Making a New Battery Last<\/h2>\n\n\n\n

You have just spent money on a new KPL944755-2S2P. A few habits will get you significantly more than the standard two years out of it.<\/p>\n\n\n\n

Heat is the enemy.<\/strong> This is the single biggest factor. Do not store the tablet on a dashboard, in a vehicle cabin in summer, or anywhere it sits in direct sun. Do not charge it in a hot environment. If the tablet is warm after a long session, let it cool before charging.<\/p>\n\n\n\n

Avoid chronic 100% and chronic 0%.<\/strong> Ideal daily range and storage is roughly 40\u201380%<\/strong>. A tablet that lives permanently on the charger ages faster; a tablet that regularly runs to shutdown ages faster in a different way. Charge when it drops to around 20%, and unplug once it is full.<\/p>\n\n\n\n

Store spares properly.<\/strong> If you keep a spare pack, charge it to 40\u201370%, store it somewhere cool at 15\u201325\u00b0C, and top it up every few months. Never store it flat \u2014 that is how packs become permanently unrecoverable.<\/p>\n\n\n\n

Keep the charger quality up.<\/strong> A poor-quality or underpowered adapter forces the tablet to work harder and may not charge reliably during diagnostic use.<\/p>\n\n\n\n

Manage load while on battery.<\/strong> If you know you will be doing heavy coding or programming, plug in first. Sustained high-current operations are exactly when a marginal pack fails.<\/p>\n\n\n\n

Test annually.<\/strong> Once a year, run the stopwatch test: full charge, normal diagnostic session, record runtime. When runtime falls below roughly half of what a new pack delivered, start planning a replacement \u2014 before it fails in front of a customer.<\/p>\n\n\n\n

Safety: Swollen Lithium-Ion Batteries<\/h2>\n\n\n\n

A swollen battery is a safety issue, not a cosmetic one. Lithium-ion cells expand when internal chemical reactions produce gas, and that expansion means the cell is failing in a way that can lead to fire or rupture.<\/p>\n\n\n\n

Signs of swelling in the X431 Pro V5 include the screen or rear housing lifting away from the body, a bulge on the rear cover, the tablet no longer sitting flat or rocking on a bench, and unusual heat, a chemical smell, or hissing.<\/p>\n\n\n\n

If you see any of these, stop using it and stop charging it \u2014 do not plug it in again even if it later feels cool. Power it off if you can do so safely without pressing on a distorted screen, and place it on a hard, non-flammable surface such as a metal bench or concrete floor, not a wooden bench covered in paperwork. Keep it away from combustible materials, solvents and anything sharp.<\/p>\n\n\n\n

Do not puncture, bend, squeeze or press the battery.<\/strong> Do not try to flatten it or press the housing back into place. Do not remove the battery yourself if the pack is visibly deformed \u2014 get professional help. Dispose of it through proper battery recycling, never in general waste, and never shipped as an ordinary parcel.<\/p>\n\n\n\n

If a battery begins smoking, sparking or making popping sounds, get away from it, alert others, leave the area, and call emergency services. Do not delay your exit to retrieve the tool.<\/p>\n\n\n\n

Workshop environments amplify the risk: solvents, aerosols, rags and paper are all nearby. Treat a swollen pack as an immediate priority, not a task for the end of the week.<\/p>\n\n\n\n

Is Replacing the Battery Worth It?<\/h2>\n\n\n\n

The X431 Pro V5 is a capable platform \u2014 Android 10, 4GB RAM, 64GB storage, an 8-inch 1280\u00d7800 display, CAN FD and DoIP support, and coverage of 200+ vehicle brands. Nothing about that hardware becomes obsolete because the battery has aged.<\/p>\n\n\n\n

The arithmetic is simple. A KPL944755-2S2P replacement battery costs roughly US40\u2013<\/code>65<\/strong>. A replacement X431 Pro V5 tablet costs several hundred dollars or more.<\/p>\n\n\n\n

If your tablet works well when plugged in but will not survive a diagnostic session on battery, you are looking at a $50 problem, not a new-tool problem. For a shop, the calculation is even more obvious: one avoided interrupted coding session pays for the battery.<\/p>\n\n\n\n

The only reasons to replace the whole tablet instead are unrelated to the battery \u2014 a cracked screen, a failed charge port with board damage, or a genuine need for newer hardware capability.<\/p>\n\n\n\n

What is the KPL944755-2S2P battery?<\/strong><\/p>\n\n\n\n

It is the internal lithium-ion pack for the Launch X431 Pro V5 diagnostic tablet: 7.6V, 6300mAh (47.88Wh)<\/strong>, in a 2S2P configuration. It is the same specification as the battery the tablet ships with.<\/p>\n\n\n\n

How long should the battery last per charge?<\/strong><\/p>\n\n\n\n

Roughly 8\u201315 hours<\/strong> of continuous use depending on workload. Light diagnostic work with the screen dimmed can reach the upper end; heavy live-data streaming, bi-directional testing and high screen brightness bring it down to the lower end. Programming sessions drain it fastest.<\/p>\n\n\n\n

How do I know if my battery is worn out?<\/strong><\/p>\n\n\n\n

The clearest signs are sharply reduced runtime, the tablet shutting down at 20\u201340% while running live data or actuators, erratic percentage readings, and charging that stops or restarts without explanation. A swollen housing confirms it. There is no detailed battery health screen on this tablet, so testing runtime directly is the most reliable method.<\/p>\n\n\n\n

Why won’t my X431 Pro V5 charge?<\/strong><\/p>\n\n\n\n

Check, in order: the USB cable and charger, debris in the Type-C port, whether the tablet is drawing more power than the charger supplies during diagnostics, temperature (cold packs will not charge), software glitches resolved by a full power cycle, and the internal battery connector seating. Only after eliminating all of these should you replace the battery.<\/p>\n\n\n\n

How much does a replacement cost?<\/strong><\/p>\n\n\n\n

Typically US40\u2013<\/code>65<\/strong>, with most mainstream sellers in the US55\u2013<\/code>65 range. Official Launch parts are more expensive and usually quote-based.<\/p>\n\n\n\n

Is it compatible with every X431 Pro V5?<\/strong><\/p>\n\n\n\n

No. This battery is not compatible with the 10-pin, 9-line version<\/strong> of the tablet. Check your original battery’s connector and part number before ordering.<\/p>\n\n\n\n

Can I install it myself?<\/strong><\/p>\n\n\n\n

Yes, if you are comfortable opening an Android tablet and working with internal connectors. Back up your data first, disconnect the battery connector before anything else, and photograph each step. If the tablet is under warranty, or the old battery is swollen, use a professional service instead.<\/p>\n\n\n\n

Will a new battery make the tablet feel faster?<\/strong><\/p>\n\n\n\n

Frequently, yes. Android power management throttles performance when a battery is weak or voltage sags under load. Technicians often attribute this slowdown to software or the VCI. If your Pro V5 feels sluggish and the battery is over two years old, replacing it is worth trying before anything else.<\/p>\n\n\n\n

How should I store a spare battery?<\/strong><\/p>\n\n\n\n

Charge it to 40\u201370%<\/strong>, keep it somewhere cool and dry at around 15\u201325\u00b0C, and top it up every few months. Never store a lithium-ion pack fully discharged for long periods \u2014 the protection circuit can lock out and the pack may become unrecoverable.<\/p>\n\n\n\n

Does the warranty cover capacity loss?<\/strong><\/p>\n\n\n\n

No. Battery capacity naturally declines with use, and that is not a defect. A 12-month warranty covers premature failure, manufacturing faults, and out-of-box problems \u2014 not the normal ageing that every pack experiences.<\/p>\n\n\n\n

The Replacement Battery KPL944755-2S2P 6300mAh<\/a> for Launch X431 Pro V5<\/strong> is a low-cost fix for one of the most disruptive problems in a workshop: a diagnostic tablet that dies when you need it most.<\/p>\n\n\n\n

Replace it when runtime has dropped to roughly half of what it once was, when the tablet shuts down with charge showing, when charging becomes erratic, or immediately if the housing shows any sign of swelling. Before you spend money, rule out the cable, the charge port, the charger output and temperature \u2014 a genuine Launch X431 Pro V5 battery not charging<\/strong> problem has several possible causes, and not all of them are the battery.<\/p>\n","protected":false},"excerpt":{"rendered":"
