Sealed battery West battery of SH38-12/ups power battery /SEHEY12v38ah/ valve control

Performance and advantage:
Very high safety and reliability
The safety valve automatically (VRLA), can prevent the gas is inhaled battery affects its performance, abnormal pressure and damage to the battery caused by gas can also prevent caused by charging. The battery has not closed in normal float under discharged electrolyte and acid mist. At the same time, the use of independent patent technology battery tray and battery matching, to ensure the use of batteries more secure.

Long service life
20 degrees in the environment, FM series of small floating sealed battery life of up to 3 to 5 years, FM stationary sealed batteries floating life can reach 8 to 10 years, FML series battery floating life up to 10 years, FMH series battery floating life up to 10 years, 15 years GFM series battery life up to float.

Low self discharge rate
The special Pb Ca alloy, impurity of separator, electrolyte and the production process are strictly controlled, at 20 OC, Okerson does not have to supply power to the battery can be used normally within 6 months.

Strong electrical conductivity
The copper plated silver terminal and special design ensure excellent electrical performance.

Strong ability to adapt to environment
It can be used at ambient temperature of -20 ~ +50 C, suitable for desert and plateau climate. Special power supply used in riot control area.

Strong directivity
The special diaphragm (AGM) firmly adsorbed the electrolyte to keep it from flowing. The battery can not leak without standing or lying, which ensures the normal use.

Green pollution free
Mute, and no pollutant discharge. The battery room needs no acid and corrosion protection measures, and can be equipped with electronic instruments and other equipment in one room.


Rated voltage
Measured voltage

Battery charging:
First, cycle charging and discharging mode
1. If the device is connected to the power supply, the battery will be powered by the battery after the charging is saturated. In this case, the cycle charging and discharging mode should be selected.
2, when charging the maximum charge voltage should be limited to provide machine: the ambient temperature at 25 DEG C, 2V battery charge pressure is 2.35-2.45V; the charging voltage of 4V battery: 4.70-4.90V battery; charging voltage of 6V is 7.05-7.35V; the charging voltage of 8V battery: 9.40V-9.80V batteries for charging voltage of 10V; 11.75-12.25V; 12V battery charging voltage: 14.1-14.7V. The maximum charging current is less than the rated capacity value of 25%A.
3, when charging saturation, should immediately stop charging, otherwise the battery will be damaged or due to excessive charge will easily cause the battery drum.
4, charge and discharge, the battery can not be inverted.
5, the cycle life depends on the depth of each discharge, the greater the discharge depth, the less the number of batteries can be recycled.
Two, the use of floating charge mode
1, if the device is connected with the power supply, and in a state of charge, just outside the power supply stops, powered by battery float charging mode should choose this case.
2, each battery battery float charging voltage setting range should be strictly controlled in the environment: 20 degrees, 2V battery float voltage is 2.25-2.30V, the maximum charge current is not greater than the rated capacity value of 25%A.
3, floating life is mainly affected by the floating voltage and ambient temperature, the higher the float voltage, battery life is short.
Three, discharge
When discharging, the battery terminal voltage is lower than the prescribed terminal voltage or multiple times of discharge, and the over discharge will cause serious damage to the battery and lead to the premature termination of the battery life.

UPS power supply maintenance free lead-acid battery according to "GB/T valve regulated lead acid battery standard"Design and manufacture, the product does not need to add water before use, the user only need to install correctly can use.". Battery hasNo acid leakage, small resistance, vibration resistance, anti discharge recovery ability, self discharge is small, long lifeOther characteristics.

Baby characteristics:
Tight equipment,No leakage, no acid pollutionThere is no need for specific environment, no water, no need to add electrolyte,Maintenance freeIt is easy to connect, no need to use in a specific direction, and the inner is small,High output powerDesign; low impedance, low self discharge, capacity retention and storage time issued more than 12 months at 20 DEG C; the C.C.D.S charge and discharge detection system, ensure product consistency; high strength engineering plastics as raw materials and high density superfine glass fiber separator, to ensure first-class quality of the battery; adapt to various temperature conditions (-15 C - 45 DEG C); no free electrolyte, explosion-proof, small self discharge.
