12v120ah battery bumper boats standard mf maintenance free battery

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. 

---Battery Life 

The adoption of Sb-free Pb-Sn-Ca special alloying technology effectively guarantees the contents of lead dioxide and spongy lead in the positive and negative plates. The battery can be put into use directly after adding liquid, no need to be charged. Its super-charged performance distinguishes the product from others. 

---Excellent Performance Chart of Pb-Ca Alloy 

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. 

---Comparison of Self-discharge between General

Accumulator and Pb-Sb-Ca Alloy Accumulator  

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.
