Storing and Charging

• If the lithium ion batteries are going to be stored for a period of time, it is recommended to store them half or fully charged. Placing the battery in a dry and cool place will help the battery maintain this charge for a longer time.
  
  When in use, lithium ion batteries should be recharged frequently. Forget everything you've ever learned about waiting until the battery is completely dead before you charge it. Unlike their predecessors, lithium ion batteries love to be recharged early and often. Letting this battery completely drain is not recommended when it comes to these batteries.
  
  

Match Right Battery and Charger

• Realize that not all lithium ion batteries can be recharged. Some are rechargeable, but others are disposable batteries that should be recycled when they are depleted of energy. Before attempting to recharge any battery, check the printed label to make sure that the lithium ion battery you have is capable of being recharged.
  
  Make sure you have the correct battery charger for lithium ion batteries as well. There are several varieties of rechargeable batteries aside from lithium ion, and no one battery charger will recharge all of the different varieties. Check to make sure that the battery charger you are using is intended to work with lithium ion batteries.
  
  Also keep in mind there is no such thing as a "super charger" that can recharge batteries faster than normal. Some chargers are promised to finish charging within an hour or even less. In reality, the battery is only charged 70 percent of its total capacity. Battery manufacturers set strict procedures on how to charge their products. It is important for users pay serious attention to these instructions.
  
  

Do Not Overcharge

• Many people think it is all right to leave the battery plugged to the power supply all night long. This proves to be unwise, especially with lithium ion batteries. Just as these batteries should not be drained completely before being recharged, they also should not remain connected directly to a power source after the battery is full.
  
  Overcharging creates heat, and batteries are subjected to heat for prolonged periods may create flames. It also consumes unnecessary electricity to leave the device anchored to the wall outlet, which costs you money on top of weakening your battery life. All of this can be avoided by simply unplugging your telephone when the charge cycle is complete.
