if they a re stored at 25 C.
Charging Method:
▶Avoid battery overcharge, especially in series connection use.
▶Charge with recommended voltage.Ensure battery fully recharges. In general, recharge
▶Effect of temperature on cycle charge voltage:-4mV/
▶The length of cycle service will be affected by depth of discharge, ambient
discharge rate, and the manner in which the battery is recharged. Generally speaking, the
most important factor is depth of discharge.
Cycle Service
Float Service:
▶
▶Every three months, recommend a one time equalization charge.
Equalization charge method:

Every month, recommend inspection of every battery's voltage.
Length of service life will be affected by the number of discharge cycles depth of
discharge, ambient temperature,and charging voltage.
capacity should be 1.1-1.15 times discharge capacity.
