Lithium Motorcycle Battery Dead

A lithium iron motorcycle battery is very light and is supposed to hold a charge for a very long time but if you re lithium iron motorcycle battery goes dead you can use a car battery charger set.

Lithium motorcycle battery dead.

You can check the age of the battery pack and measure the voltage if able or check for date codes on the circuit board inside. Lithium battery failures the technology has advanced enough to include battery management systems bms which balance the discharge and recharge loads. Most of the time these batteries will be dead and i mean dead. Bms shuts down the battery if an overcharge is detected to prevent overheating and the potential to catch fire.

This should take around 3 hours depending on what type of li ion battery you are reconditioning. If your lifepo4 battery has stayed at low voltage for very long. So yes a dead battery pack may be jump started by simply applying a charging voltage until the cells regain an appropriate voltage allowing the battery management system to reconnect for discharge. A healthy motorcycle charging system puts out about 14 volts at 2 000 rpm and a lithium battery needs between 13 and 14 volts to charge.

What hurts batteries of all types is staying dead for very long. Remember usb is only 5v so your dead li ion battery needs to be rated under that. It may not recover and or lose it s rated ah capacity. Lithium ion cells don t like to be discharged below their over discharge voltage usually between 2 5 and 2 75 volts at the most.

However many li ion battery systems on the market are made from large prismatic cells connected to an external management system. But it s not recommended to drop below 12 85 20 for max life.
