Accumulator group is base part of a when the station comes true to shed uninterrupted power supply continuously important composition, its investment and equipment of frame power source comparative basically. What at present shift radical station uses is 20 centuries end develops a powerful person that rise to charge pattern accumulator of sealed lead acid (abbreviation VRLA batteries) . Because used a powerful person to charge pattern sealed structure, do not need to add acid, add water to safeguard, release of the fluid that do not have acid, acerbity mist exceeds, can put with the computer room with equipment. As a result of bulk small, weight is light, safeguard smally, less from discharge, life is long, use the characteristic such as convenient, on the safe side, welcome by the user. But we must see however, on one hand the basic electrochemistry principle of this kind of batteries still did not change, its consequently inherent report character asks to did not change not only, ask instead more severe; On the other hand this kind of batteries is popularizing initial stage, the manual of manufacturer is what this kind of batteries says more or less batteries of “ maintenance-free ” sometimes, send a part to safeguard personnel to think this kind of batteries does not need to safeguard, this one error is returned up to now influential. Strengthen scientificly consequently the maintenance to this kind of accumulator group and maintaining still is very important to increasing its availability.

It is to should have prevented to fill. The life of accumulator and function and the heat that batteries interior produces are accumulated closely related, and the reacts at in-house electrochemistry power loss that the heat source of batteries interior basically comes to, look at OK and simply charge the product of voltage and charging current. In oxygen again in chemical combination reaction, float fills electric current to be able to increase and produce more quantity of heat, when constant voltage charges, float is filled electric current can rise along with temperature again and increase, make temperature rises further again thereby. The peculiar appearance that the structural means place that heats up out of control to seem a powerful person to accuse sealed cell now creates. If batteries dehydrates,hot out of control often brings serious harm, ’ of abdomen of crust ‘ beat, serious person cause batteries to discard as useless. Had prevented to fill even if should press manufacturer manual strictly to offer charge voltage value. Present assorted power source all can be installed, realize the management that intelligence turns, those who need an attention is it is to should be installed above all correct, it is without accredit personnel can not alter casually usually next.

2 it is to should prevent undercharge. Had mixed fill just in time contrary, undercharge basically is to charge to voltage sets on the low side or cross low be caused by. Or frame system appeared problem.
