How to Charge a Lithium Battery
Lithium ion batteries act as a power source for many types of electronic devices such as portable games devices, cell phones and digital cameras. Lithium ion batteries are rechargeable and can be charged using a battery charger. Lithium ion battery chargers can be purchased from a variety of stores.
- Purchase a lithium ion battery charger from your local electronics store. The charger must be able to deliver 3.8 to 4.2 volts to each cell to charge the battery completely. Read the specification on the battery charger box, or ask a store associate to help you find the right type of battery charger.
- Place the lithium ion batteries inside the charger. Plug the charger into a power outlet and switch it on. Some types of lithium ion battery chargers automatically begin charging the batteries. A red LED light will be displayed when the batteries are charging.
- Allow the batteries to charge for four to six hours. It may take more or less time, depending on how discharged the batteries were. When the batteries are fully charged, the LED light will change from red to green. Do not leave the batteries in the charger once they have fully charged. This can cause them to explode or leak and could cause a fire.
- Remove the lithium ion batteries from the charger, and place them in the electronic device that requires them. Unplug the charger, and store it in a safe place. Use the charger as often as necessary to charge your lithium ion batteries.
