The maintenance free battery slot cover and pole double seal design, the oxygen adsorption efficiency of composite glass can effectively control the internal battery water loss, do not have to regularly fill with water or sulfuric acid, during the entire life without fluid maintenance. The connection is convenient, without the use of a particular direction; Yin in small, high output power; low impedance design, low self discharge, and storage capacity retention time in 20 degrees, issued more than 12 months; the C.C.D.S charge and discharge detection system, ensure product consistency; adopt high strength engineering plastics as raw materials and high density superfine glass fiber separator, to ensure first-class quality of the battery; adapt to various temperature conditions (-15 C and 45 C) no free electrolyte, explosion proof, long life, vibration resistant performance, anti over discharge recovery ability.
The safety valve can be automatically opened and closed, to prevent external gas is inhaled and destroy the battery internal battery performance, flame retardant one-way exhaust system, in the process of using no leakage, no fire. The Pb-Ca alloy quality, improve the hydrogen evolution overpotential, lower self discharge rate of the battery at 20 DEG C, the battery does not need to add electricity can be used within 6 months. High discharge: 25 degrees Celsius, the state of the fully charged battery constant resistance discharge 3 weeks (the resistance value is equivalent to the battery 1CA discharge requirement), recovery capacity above 75%. Because of the small internal resistance, the discharge characteristics of high current are good.
Regularly check the status of the battery, keep the battery room and battery container, stent, shell clean. Regularly check the battery connection terminals, so that they are in good contact, to prevent the current discharge when the spark and pressure drop phenomenon. If UPS is running 2 ~ 3 month period rarely occurred in power failure or no blackout phenomenon, should be subject to check and discharge, electricity artificially disconnected, release the battery capacity from 30% to 40%, and then plugged in normal operation. The battery which is ready to be deactivated should be charged before the battery is stopped. After placing, charge once every 1~2 months.

Candice Contest battery lead-acid battery is composed of positive and negative plates, plate, shell, electrolyte and wiring pile head, the discharge chemical reaction is dependent on the positive plate active material (two lead oxide and lead) and negative plate active material (sponge pure lead) in the electrolyte (sulfuric acid) are under the action of the gate frame the plates, with lead antimony alloy manufacturing traditional battery, maintenance free battery is made of lead calcium alloy, the former for the latter with antimony, calcium, this is the fundamental difference between the two. Different materials will have different phenomenon: the traditional battery will reduce the phenomenon of liquid in the process of using, this is because the gate frame of antimony can sponge pure lead pollution on the negative plate, weakening the back EMF in the storage battery is fully charged, resulting in excessive decomposition of water, large amount of oxygen and hydrogen. From the positive and negative plate to reduce the escape of electrolyte. Using calcium instead of antimony, can change the battery fully charged after the counter electromotive force, reduce the charging current, liquid gasification rate decreased, thereby reducing the loss of electrolyte
