How to Activate a Battery?
1 Answers
Find a set of batteries of the same model as the original battery and connect them in parallel with the set of batteries that cannot be charged, allowing the good batteries to discharge into the unchargeable ones. Use a small charger to initially charge this set of batteries, then switch back to the original charger to continue charging. You can try fast charging for one to two hours and use a professional tester to check if the voltage has increased.
