Product Details

OPzS2-1200-Y of Best OPzS Battery

The most important components of a lead-acid battery that can provide electrical energy are positive, negative plate and electrolyte. The specific gravity and liquid amount of the electrolyte is equally important for providing electrical energy. The lack of solution according to different situations, timely replenishment of battery solution or distilled water, otherwise it will shorten the battery life! Then, test the electrolyte proportion is higher than the lowest level, to complement the acid. If the results of the test specific gravity change little, it can be used. If the proportion is low, it shows that the battery is short of electricity for some reason. It should be supplemented for a certain time to ensure the battery life.

Product Features of Best OPzS Battery

Self discharge rate


Cycle life

>2200 at 80% DOD

Positive plate

tubular type, with die-casting thick Pb-Ca grid, it has very good

corrosion resistance
