Regular maintenance of the battery module is an absolute necessity. Periodic inspections of battery and terminal voltages, specific gravity, and connection resistance should be made. Strictly follow the procedures outlined in the battery manufacturer’s manual.
Since individual battery characteristics are not identical, and may change over time, the UPS module is equipped with circuitry to equalize battery cell voltages. This circuit increases charging voltage to maintain flooded type battery cells at full capacity.
NOTE
Do not use equalize charging with
Consult the battery manufacturer's manual for specific information about equalize charging.
The equalizing charge time period is adjustable from zero to 72 hours and can be initiated automatically or man- ually. Refer to 3.0 - Operation.
