Battery Information

GENERAL BATTERY INFORMATION
Most rechargeable devices use Lithium-Ion (Li-ion) polymer batteries these days. This type has high energy density, very low memory effect and low self-discharge. You can find them in electric cars, golf carts, power tools and other applications, besides portable headphones, telephones and loudspeakers. Various subtypes exist that have different strengths and weaknesses, depending on the chemicals and metals used. Batteries gradually self-discharge, even if they are not connected to anything. Usually, you can expect a self-discharge of about 2% per month when the battery is new, and this may increase somewhat with battery age and temperature.

BATTERY LIFE
The life expectancy of Li-ion batteries is 500 to 1000 recharging cycles. You can expect full capacity until you have recharged about 500 times. From 500 to 1000 recharging cycles, capacity will decrease gradually, until almost no capacity is left, and the battery will need replacing, if this is possible and economical. Life expectancy is optimal when the battery is being used between 10 and 50 degrees Celsius.
