To fix a lithium-ion battery not charging: Check charger compatibility and power source. Clean charging ports with compressed air. Reset the battery via full discharge/recharge. Replace damaged cables or batteries. For detailed steps, troubleshooting, and revival methods, read below. Part 1. Why is the lithium battery not charging? Faulty Charger
Frequent Overheating: If the battery overheats during charging or usage, it may be failing. Overheating can indicate internal issues. Charging Problems: If the battery takes an unusually long time to charge or does not charge at all, it may require replacement. Age: Most lithium-ion batteries have a lifespan of 2 to 3 years.
Over time, the BMS can become misaligned, leading to calibration issues that prevent the battery from charging. Physical damage, such as a puncture or a crack, can cause a lithium-ion battery to malfunction. Similarly, corrosion on the battery terminals or connectors can prevent charging.
Understanding what causes lithium batteries to fail helps in determining whether a repair is feasible. Failures are often linked to physical wear, chemical aging, or firmware glitches within the battery’s management system. At UpFix, we analyze every returned unit to pinpoint the root cause.
Like any other battery technology, lithium-ion batteries degrade over time due to wear and tear. As the battery ages, its capacity to hold a charge reduces, and it may eventually refuse to charge altogether. In some cases, the battery may have been defective right from the manufacturing stage.
Even if your lithium battery model isn't listed, we may still be able to repair it. UpFix offers custom diagnostics for uncommon, international, or older models. Just provide the part number or a photo of the label. Our technicians will evaluate compatibility and let you know the next steps.
