Product properties:

discharge
(1) the battery should not discharge to below the desired terminal voltage, otherwise it will lead to over discharge, and the repeated over discharge will cause the capacity difficult to recover. In order to achieve the best efficiency, discharge should be between 0.05-3C, discharge termination voltage is shown in Table 1

(2) 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 (below 15 degrees Celsius, 5 degrees Fahrenheit.) it will reduce the effective capacity, high temperature (122 degrees Fahrenheit higher than.50 DEG C) will lead to thermal runaway and damage the battery.

Charge

(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). Please refer to table (2).

(2) cycle use (charging, stopping, discharging is charged): charging voltage 2.4V/ monomer, the maximum charging current shall not be greater than 0.25C10.

(3) the temperature compensation battery 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 4mv/ C / single (body temperature to 25 DEG C for reference).

(3) overcharge

After the battery is fully charged, the additional power is called overcharge. Continuous overcharge will shorten the life of the battery.

Service life

The following factors may shorten the service life of the battery:
Repeat the deep discharge.
Shallow deep discharge after repeated charging.
The outside temperature is too high.
* overcharge - especially a float charge
Large charging current.
When you charge the battery if not used for a long time, especially in the high temperature environment, will lead to reduce self discharge and capacity.

Capacity retention and storage

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 has not been used, it will cause self discharge due to the chemical and electrochemical reactions inside the battery:

A. chemical factors, whether PbO2 or Pb, need to be decomposed or gradually reacted with sulfuric acid (electrolyte) to change into a more stable lead sulfate, which is spontaneous 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

The battery should be charged immediately after discharge, and the battery can not be put into use for a long time after discharge. The battery should be recharged again after a period of time, until the capacity is restored to the level before storage.

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 recombination efficiency of the adsorbed glass can effectively control the loss of moisture in the battery, so no water supply or acid maintenance is needed during the use of the whole battery.
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 low calcium lead alloy grid designed by computer can greatly reduce the production of gas and can be reused conveniently, which greatly prolongs 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

Range of use:
UPS uninterruptible power supply, alarm system, emergency lighting system, post and telecommunications, power system, power plant power switch control and accident treatment,
The bank uninterrupted system, telephone and telecommunications equipment, electric toys, fire protection, security systems, medical equipment, solar system, ship equipment, control equipment, electronic equipment and other standby power supply.
