How to Revive Laptop Lithium-ion Batteries?
Lithium-ion batteries, also known as Li-on batteries, are rechargeable, making them a good choice for all electronic devices, from laptops to camcorders. The advantages of lithium-ion batteries over NiCad batteries and NiMH batteries are higher capacity, lower self-discharge, and a higher number of charge cycles before problems develop. Before you dispose of a lithium-ion battery that appears to have died, try bringing it back to life first.
Things You'll Need
Turn off the power source to the appliance containing your battery and remove the battery. Take a voltage reading with your voltmeter. Lithium-ion batteries may go into sleep mode if you drain the battery too much. For example, if your battery is rated at 3.7 volts and the voltmeter only shows 1.5 V, it may be in sleep mode.
Some battery chargers and analyzers have a "wake up," "recovery" or "boost" feature designed to wake a sleeping battery. This isn't always successful, and you shouldn't try it with batteries below 1.5 V for over a week, but sometimes it will revive the battery. Insert your battery, taking care to insert it in the correct polarity.
