Characteristics of sun god free maintenance battery

 

1, good safety performance: normal use without electrolyte leakage, no battery expansion and rupture.

2, discharge performance is good: discharge voltage is stable, the discharge platform is gentle.

3, good vibration resistance: fully charged state of the battery is completely fixed, with 4mm amplitude, 16.7Hz frequency vibration for 1 hours, no leakage, no electricity

The pool expands and breaks and the open circuit voltage is normal.

4, good impact resistance: fully charged state of the battery from 20cm high drop to 1cm thick hardwood board 3 times. No leakage, no cell expansion

And breakdown, open circuit voltage is normal.

5, good resistance to over discharge: 25 degrees Celsius, fully charged state of the battery for constant resistance discharge 3 weeks (resistance value equivalent to the battery 1CA put

The electrical resistance is required, and the recovery capacity is above 75%.

6, over charge good: 25 degrees Celsius, fully charged state of the battery 0.1CA charge 48 hours, no leakage, no battery expansion and rupture, open

The road voltage is normal, and the capacity maintenance rate is above 95%.

7, good resistance to high current: fully charged state of the battery 2CA discharge 5 minutes or 10CA discharge 5 seconds. No conductive part fuse, no appearance

Deformation.

 

Maintenance free lead-acid batteries applications: uninterruptible power supply, marine equipment, medical equipment, alarm system, engine starting, electric tools, emergency lighting, standby power supply, large UPS and computer standby power supply, the peak load compensation of energy storage devices, power systems, telecommunications equipment, control system, power station, nuclear power station. Fire and security systems, solar energy, wind power station

Maintenance free lead-acid battery safety performance is very good. The maintenance free battery because of its advantage in structure and consumption of the electrolyte is very small, the service life of the basic does not need to add distilled water. It also has the characteristics of high temperature resistance, shock resistance, small volume, small self discharge. The service life is two times as common as that of ordinary batteries.

Essential characteristics

Safety seal

In normal operation, the electrolyte will not leak out from the terminal or shell of the battery.

No free acid

The special liquid separator keeps the acid inside, and there is no free acid inside the battery, so the battery can be placed in any position.

Deflating system

The internal pressure of the battery is beyond the normal level, VRLA (namely "Valve-RegulatedLeadAcidBattery VRLA battery" abbreviation) will release the excess gas and automatically re sealed to ensure that no excess gas in the battery.

Simple maintenance

Because of the one and only gas compound system makes gas into the water, in the use of VRLA (namely "Valve-RegulatedLeadAcidBattery VRLA battery" abbreviation) battery is not needed in the process of water.

Long service life

The lead calcium alloy board VRLA corrosion resistance structure (i.e. "Valve-RegulatedLeadAcidBattery VRLA battery" abbreviation) battery float 10-15.

The quality is stable and the reliability is high

The use of advanced production technology and strict quality control system, VRLA (namely "Valve-RegulatedLeadAcidBattery VRLA battery" abbreviation) stable quality, reliable performance. Voltage, capacity and seal are tested on line 100%.

Product performance:

discharge
(1) the battery should not discharge to less than a predetermined termination voltage, 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) 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).
(Table 2) charging method and charging time


(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). (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) 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.
