A, circulating usage patterns
1, if the device is connected to the power supply, leave the power supply by the battery after charging saturation, this kind of circumstance should choose circulation charge and discharge.
2, when charging machine provided by a charging circuit voltage should be * * limitations: the environment temperature at 25 ℃, 2 V battery charging charging - as follows: 2.35 to 2.45 V. Battery charging voltage is 4 V: 4.70-4.90 V. Charging voltage of 6 V battery are as follows: 7.05 to 7.35 V. 8 V battery charging voltage: 9.40 V to 9.80 V; 10 V battery charging voltage as follows: 11.75 to 12.25 V. The 12 V battery charging voltage is: 14.1-14.7 V. Charge current is not more than 25% of the rated capacity values * * A.
3, charging saturation should immediately stop charging, or the battery will be damaged or caused by excessive charging can easily drums outside the cell.
4, charge and discharge, battery not upside down.
5, recycled life depends on the depth of each discharge, discharge the depth, the greater the battery cycle the less the number of times.
Second, the floating usage patterns
1, if the device is always connected to the power supply, and in charging status, just outside the power to stop when the battery power supply, this kind of circumstance should select float charge mode.
Section 2, the battery pack each float charge voltage setting range should strictly control: in 20 ℃ environment, float charging pressure of 2 V battery are as follows: 2.25-2.30 V, * * charging current is not more than 25% of the rated capacity values A.
3, the service life of the floating was mainly affected by float charging pressure and ambient temperature, float charging voltage is higher, the battery life is short.
Third, discharge
When discharge voltage of the battery under provisions of the termination voltage or many times over discharge, over discharge will bring battery severely damaged, make the battery life of early termination.
UPS power supply and maintenance-free lead-acid battery according to the GB/T control valve sealing type lead-acid battery standard design and manufacture, products without adding water before use, the user can use with correct installation. Battery has no acid leakage, small resistance, shock resistance, resistance to discharge recovery capability is strong, small self-discharge, long service life, etc.
