Can A Dead Lithium Battery Be Recharged. Take the battery pack out of the way. A dead or non-functional lithium-ion battery can be resurrected by using some convenient simple tools.
Return the battery into the lithium-ion charger and give it a full charge which should take around 3 hours depending on what type of Li-ion battery you are reconditioning. For example if your battery is rated at 37 volts and the voltmeter only shows 15 V it may be in sleep mode. Lithium-ion batteries may go into sleep mode if you drain the battery too much.
If they could be recharged and life expanded they would have found a way considering how many billions they have in funds.
For example if your battery is rated at 37 volts and the voltmeter only shows 15 V it may be in sleep mode. A lithium ion battery state of charge is not the same as the voltage. This may happen due to overuse or leaving the battery for too long on the charger. Remember that sometimes reviving a battery will not work so you might just have to buy a new battery if this isnt successful.
