Design Life 20 years (floating charge) DC (Deep Cycle) series batteries provide superior high integrity and reliabil i ty.It is specially designed for frequent cyclic charge

and discharge .By using strong grids , thick plate and specially active material are designed

for repeated deep-discharge appl icat ions .

The DC series batteries offer 30% more cyclic

life than the standby series.It is suitable for

solar and wind renewable nergy storage,mobility

and medical equipment,V,telecom,broadband

and cable TV,UPS systems etc.

The battery must be fully charged before the capacity test. The C10 should reach 95% after the first cycle and 100% after the third cycle.
