Cycle service
※ Avoid battery over discharge, especially battery sereis connection use.
0.2C＜（A）＜1.0C
（A）≥1.0C
※ Charged with recommend voltage, ensure battery can be full recharged.
In general, recharge capacity should be 1.1-1.15 times discharge capacity.
Charge the batteries at least once every six months,
o
if they are stored at 25 C.
※ Effect of temperature on cycle charge voltage: -4mV/℃/Cell.
Charging Method:
※ There are a number of factors that will affect the length of cyclic service.
