ups battery how to properly use
New battery charging
After the new battery is installed, it is generally necessary to carry out charging for a long time. The charging should be carried out according to the regulations in the manual. After the battery pack is charged, discharge is performed once, and the battery is recharged after discharge to extend the service life of the battery. Improve battery activity and charge and discharge characteristics.

Regular charge and discharge
If the UPS battery is not used for a long time or the battery is in a floating state for a long time without discharging, a large amount of lead sulfate in the battery is adsorbed to the cathode surface of the battery, resulting in an increase in internal resistance and a decrease in activity, so that the service life of the battery is greatly shortened. For units with good power supply, it is necessary to perform a “therapeutic” charging and discharging process every three months, that is, the battery is loaded and discharged, recharged, and the relevant data is recorded, and the performance of the battery is compared with the previous discharge record. The maintenance and inspection of the battery pack as a whole can effectively protect the load when the power failure occurs.
Deep discharge is strictly prohibited
The service life of the battery is closely related to the depth of discharge of the battery. Deep discharge will cause the surface of the internal plate of the battery to be sulphated, resulting in an increase in the internal resistance of the battery. In severe cases, the "reverse polarization" phenomenon of the individual battery and the permanent damage of the battery may occur. The depth of discharge of the battery seriously affects the service life of the battery. Do not force the battery to be in a deep discharge state.
Regularly measure battery float voltage and internal resistance
With the extension of UPS usage time, the charging and discharging characteristics of some batteries will gradually deteriorate, the internal resistance increases, and the terminal voltage drops significantly. It needs to be discovered and replaced in time, otherwise it will affect the use of the whole battery. The performance of this kind of battery cannot be solved by relying on the charging circuit inside the UPS. There are hidden dangers in the continued use. It is necessary for maintenance personnel to periodically check and check the voltage and internal resistance of each single battery, and find out the battery beyond the scope for confirmation and timely. replace.
Other considerations
1 Each battery pack should be charged in time after discharge;
2 Do not charge the battery pack with overcurrent or overvoltage;
3 The battery should be avoided for long-term use, and it should not be floated for a long time without discharging.
