UPS & EV Series VRLA Batteries

VRLA Battery is an advanced type of lead acid storage batteries. It has the features of leakproof, maintenance free, low internal restitance, good low temperature performance and low self discharge. Therefore, the battery can be typically used as stand-by power for UPS. They can be also used as the power supple for portable tools, medical instruments and equipments, video recorders, communiaction systems, emergency lighting, electronic cash registers, logic systems, burglar alarm systems and so on. In additional, as a new type of batteries, they can be used for motorcycles and cars.

It is valve-regulated and composed of multi-elements lead-calcium alloy grid and absorbent glass-fiber separator. The battery has the features of low price, beautiful external form, leakproof, no acid fog, no pollution, low self discharge, low internal resistance, amall volume,small weight and maintenance.
