1. No free acid inside the battery, and there is a highly efficient gas recombination.
2. A special alloy of grid and superior electrolyte secures the battery life.
3. Reliable sealing technology, safe and reliable.
4. Strict selection of materials and advanced manufacturing technology, Low self-discharge.
5. Wide Application: Communication Power supply, UPS, DC Supply, Control Equipment, etc.
Charge
Floating charge: Charged under the limit-current of 0.3CA, and the constant voltage is 13.65V/piece(25°c).
Equalizing charge: The equalizing voltage is 14.1~14.4V/piece (25°ºC).
If the operating temperature varies significantly from the center value (25°C), temperature compensation for the charging voltage is recommended. The recommendation is -18mV/C/piece for float use and -24mV/c/piece for equalization use.
