Most cell phones, tablets, laptops and portable music players in use today use Lithium-ion batteries. Lithium-ion, or Li-ion, batteries are popular for their high energy density with no memory effect. These batteries will last longest if the battery is kept charged; allowing them to become fully discharged will quickly lower their maximum capacity. Thus, a battery charger is an essential component of modern portable electronics.
A typical charger charges a battery up to 85% of its maximum capacity in under an hour. The remainder of the multi-hour recommended charging time is used to trickle-charge the battery up to 100% capacity. In order to do this, the charger must be a ‘smart’ charger capable of sensing the battery's condition and responding accordingly. A smart charger can be designed for use with a smart battery pack, which has internal circuitry capable of sensing the battery's charge state and transmitting it to the charger.
In order to store Li-ion batteries for an extended time they should be charged to 40% of maximum capacity and stored in a cool place. To extend their life even further, batteries can be stored in a refrigerator but should never be frozen.
Lithium-ion batteries are even used in power tools and electric vehicles. Electric wheelchairs, pedelec pedal/electric bicycles and remote-controlled vehicles all benefit from the light weight and high performance of Lithium-ion batteries.
