Battery Knowledge

• What is rechargeabel battery self discharge?
  Primary battery or full charged secondary battery, when put aside for a period, it s capacity will decline or lose,this phenomenon calls self discharge that is electricity flee away.It is decided by the inner electro-chemistry system, similar to water leakage from pond or reservoir.
• What is the ambient temperature affects the battery performance?
  Low temperatures (e.g. -15^oC) will obviously reduce Ni-Cd and Ni-MH battery discharge rate. At -20^oC electrolyte is at its freezing point, charge speed will greatly slow down. At low temperature (under -15^oC) charge will raise the internal gas pressure and probably unseal the safety vent. Ambient temperature of 5^oC to 30^oC is the best range to get effective charge. Generally with temperature rising charge efficiency will become higher. But when the temperature rises to 45^oC or higher, the materials performance in the battery will be degenerated and battery service life will be shorten greatly.
