Features:
(1) When it is safe surroundings, maintenance free, and add water is not need.
(2) Equalization charges are not required and cycle or standby (or float) use.
(3) Long life for 3 year.
(4) low resistance and energy output is more remarkable.
(5) Fully enclosed (not liquid leakage, no acid gas spill).
(6) Low self-discharge rate.
