L self discharge
(1) when the charging battery after long term storage, its capacity will be gradually reduced, and a discharge state, this phenomenon is called self discharge, and this phenomenon is inevitable. Even if the battery is not used, will be due to internal battery chemical and electrochemical reaction caused by self discharge, the battery self discharge conditions are as follows:

A. chemical factors whether Yang plate (PbO2) or (Pb) of the cathode active material, are subject to decomposition or gradually with sulfuric acid (electrolyte), and converted into stable lead sulfate, this process is self discharge.

Because of the existence of impure substances, the electrochemical factors of B. may cause the formation of partial circuit or redox reaction with the poles, resulting in spontaneous discharge. Because of the low impurity content, the self discharging capacity of the battery is very small, which is due to the super retention characteristics of the battery.

(2) the self discharge of the battery is closely related to the storage temperature

Battery discharge immediately after charging, the battery discharge in not long after use; do not need to use the battery use after a period of time should be repeated to add power, until the return to the level before the storage capacity.

When the capacity is only less than 40% of the rated capacity (the open circuit voltage is lower than 6.3V/12.63V at 25 degrees), the equalization charging is applied to recover the capacity.

Room temperature should be three months once the battery charge, (supplementary methods please refer to table 3) low temperature battery can be stored for longer periods of time, such as a battery storage at 15 deg.c, no wet, clean and no sunlight, in charge necessary before, can be maintained for more than 12 months.

Battery features:

The double seal design of battery cell cover and pole is adopted to ensure no leakage of acid.
The oxygen adsorption efficiency of composite and glass can effectively control the internal battery water loss, so the process of using the battery without water or acid repair maintenance.
It is safe and reliable, special sealing structure, flame retardant one-way exhaust system, it will not leak in the process of using, and will not happen fire.
The use of computer and fine design of low calcium lead alloy grids, minimize the gas generation, and can be easily recycled, greatly prolong the service life of the battery.
The thick plate, the heat seal of the groove cover, the battery design of multi cell make the installation and maintenance of the battery more economical. The body weight is higher than the energy, the internal resistance is small, and the output power is high.
The charge discharge performance is high, and the self discharge is controlled below 2% a month (20 C).
Recovery performance is good, in deep discharge or charger failure, the short circuit placed 30 days later, can still charge to restore its capacity.
It has good temperature adaptability and can be safely used at -40~50 centigrade.
- no need to balance the charge, because of internal resistance, capacity and floating charge voltage consistency, ensure that the battery during use without a balanced charge.
And the electrolyte is adsorbed on a special separator, flowing, anti gush, can be established, or placed end to side side.
Full charge factory, free electrolyte, water and Lu Yunshu with no dangerous material
