（1The battery should not) discharge to less than a predetermined terminationVoltage, otherwise it will lead to excessive discharge, and discharge repeatedly will result in capacity is difficult to restore, to achieve the best efficiency of discharge should be between 0.05-3C, the end of discharge voltage as shown in Table 1
(2) the discharge capacity
The relationship between the discharge capacity and discharge current, figure 1 is FM, JFM series battery at different discharge rate under the condition of discharge capacity, can be seen from the figure, the greater the discharge rate, the battery can release capacity is small.
The effect of temperature
Influence of battery capacity also affected by temperature, low temperature (less than 15 degrees, 5 degrees Fahrenheit.) it will reduce the effective capacity, high temperature (.50 degrees Fahrenheit higher than 122) will lead to thermal runaway and damage the battery.
(1) (float voltage limit, current control): float voltage 2.25V ~ 2.30V/ monomer, the maximum current shall not exceed 0.25C10, the charge current to the battery is less than 2mA/AH. (25 C). (see Table 2).
(2) recycling (stop charging, put the electric charge): charging voltage of 2.4V/ monomer, the maximum charging current shall not exceed 0.25C10.
(3)Battery temperature compensation in 5 ~ 35 degrees within the scope of work, do not have to compensate the charging voltage, when the temperature is below 5 DEG C or higher than 35 DEG C, recommend appropriate adjustment of the charging voltage, adjust the standard for floating dry 3mv/ C / monomer recycle monomer (C / 4mv/ dry temperature the degree to 25 degrees for reference).
The battery fully charged before power supply is called over charging, overcharge will shorten the lifetime of the battery lasts.
The following factors will shorten the battery life:
Maintain and storage capacity
AWhether it is chemical factors. 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.
BElectrochemical factors because of impurities exist inside the battery will form a local circuit or a redox reaction with the poles, caused by self discharge. Power battery electrolyte because of the impurity content is very low, so the self discharge is very small, this is due to the super battery retention characteristics.
(2) the self discharge of battery and storage temperature are closely related
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 40% or lower than the rated capacity (open circuit voltage at 25 DEG C below 6.3V/12.63V), in order to make the application of equalization charging capacity recovery.
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.
·The battery slot cover and pole double seal design to ensure no leakage of acid.
