Ways to Revive Lithium Ion Batteries — Li Ion AAA Rechargeable Batteries

From:CTECHI GROUP Limited     Release time:2018-09-20

Overview:Lithium-ion batteries, which we also call Li-on batteries, are a kind of rechargeable batteries. In lithium-ion batteries, there are different sizes, such as aa li ion rechargeable batteries and li ion aaa rechargeable batteries. Nowadays, they are popular and good choice for all types of electronic devices, from small to smartwatches and big to laptops. NiCad batteries and NiMH batteries, lithium-ion batteries have more advantages, higher capacity, lower self discharge, as well as a higher number of charge cycles before problems develop. Before you dispose of a lithium-ion battery that appears to have died, there may be a chance to bring it back to life first.

1. Read the Voltage

Cut off the power source to the appliance which is using your battery, and remove the nearly out of power battery. Use a voltmeter to read the voltage of the battery. Lithium-ion batteries may go into sleep mode if you drain the battery too much. For example if you have been using 3.7 volt rechargeable lithium-ion battery for a long time and it will become the same voltage as an 1.5 volt lithium battery, it may be in sleep mode.

2. Connect to a Healthy Battery

Take an unused battery, which has the same voltage as the dead one, and connect them with crocodile clips. Remember to connect positive to negative so as to create a working circuit. Leave the batteries connected for 10 to 15 minutes, keeping an eye out for signs of damage and overheating.

3. Read the Voltage Again

Take another voltage reading of the drained battery. Hopefully, it now has a much bigger voltage and will be abble to accept a charge.

4. Charge and Discharge the Battery

Plug the battery into the lithium-ion charger and charge it to full energy, which should take around 3 hours depending on what type of Li-ion battery you are using. Next, discharge the Li-ion battery again in a device that is highly energy-consuming, like an LED flashlight.

5. Freeze the Battery

Seal the Li-ion battery in an airtight bag and put it in the freezer or refrigerator for about 24 hours, ensuring there is no moisture in the bag in advance in case that it could get the battery wet. When you take it out of the freezer or refrigerator, put it in the shade for up to eight hours to restore it to room temperature.

6. Charge the Battery

Place the Li-ion battery in the charger and charge it fully. Hopefully, its performance will improve, it will take a charge again and last longer between charge cycles.

7. Warning

The electrolyte inside a Li-ion battery is flammable and the cell itself pressurized. Always wear safety glasses when working with batteries.
