Specification
(12V260Ah)
DG (Deep Cycle GEL , 12 Volts ) series is pure GEL battery with 12 years
floating design life , it is ideal for standby or frequent cyclic discharge
applications under extreme environments. By using strong grids, high
purity lead and patented Gel electrolyte, the DG series offers excellent
recovery after deep discharge under frequent cyclic discharge use, and
can deliver 400 cycles at 100% DOD. Suitable for solar, CATV, marine , RV
and deep discharge UPS, communication , and telecommunication , etc.

※ Avoid battery over discharge, especially battery sereis connection use.
Charge the batteries at least once every six months,
o
if they are stored at 25 C.
※ Charged with recommend voltage, ensure battery can be full recharged.
In general, recharge capacity should be 1.1-1.15 times discharge capacity.

※ Effect of temperature on cycle charge voltage: -4mV/℃/Cell.
※ There are a number of factors that will affect the length of cyclic service.
The most significant are depth of discharge, ambient temperature,
