DURABILITY

1.      in voltage by Composite Separator

Ultra-fine glass fiber composite separator, with light weight, small resistance, high acidity absorption and strong ion migration ability in the sulfuric acid solution, improves its battery voltage and starting current to the maximum, thus keeping the battery capacity in a good state all long.

2.      in battery life by Composite Separator

Ultra-fine glass fiber composite separator, with the fiber diameter of 2-3um, is arranged disorderly in a network structure. The strong adsorption and breakover capabilities of the battery electrolyte can effectively condensate active substances and prevent them from dropping off, thus extending the battery life.

3.     in Circle-Index by the High-Purity Pb(99.99%)-Ca accumulate plate

The accumulate plate made of high-purity Pb-Ca alloy has extraordinary oxidation and corrosion resistance capabilities. The adverse effect brought about by hydrogen evolution of general Sb alloy plate is avoided; the water loss of the accumulator slowed down, and the cycle index improved.

4.     in Storage-Period by the High-Purity Pb(99.99%)-Ca accumulate plate

The Pb-Sb-Ca alloy grid offers more excellent characteristics of oxidation resistance, corrosion resistance and less water loss than the general Sb alloy grid, which can minimize the self-discharge and maintain its good starting performance even after long-term storage.
