VRLA battery 1,Long service life 2,low self-discharge 3,Sufficient capacity
4,Good sealing capability

Zlpower sealed lead-acid rechargeable battery (VRLA battery) is leak-proof and maintenance free. The Superiority of Zlpower battery is derived from its uniquely efficient oxygen recombination technology. The oxygen evolved from the positive plates diffuses through the micro porous glass fiber mat to the negative plates where it is changed back to water by recombination reaction, eliminating the need for water addition. The result is a maintenance free battery.

[ No Free Acid ] All of the electrolytes are absorbed into the positive plates, negative plates, and the micro porous glass fiber mat. There is no free acid inside the battery, therefore the VRLA battery can be mounted in any location.
[ Safe and Sealed ] The unique construction and sealing technology ensure that no electrolyte leakage can occur from the terminals or cases of any VRLA batteries.
[ Maintenance-Free Operation ] During the expected service life, there is no need to check the specific gravity of electrolyte or to add water.

[ Long service Life] The Zlpower battery designed to have 500 times charge and recharge cycle.
