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
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.
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.
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.
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%.
(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.
(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).
After the battery is fully charged, the additional power is called overcharge. Continuous overcharge will shorten the life of the battery.
The following factors may shorten the service life of the battery:
