Technical requirements for battery equalization repair instrument

How often should a battery be equalized?

Equalization time will vary depending on the level of sulfation, balance of charge, size of the battery bank and available charging source. Typically, a corrective Equalization is necessary every 60 to 180 days to desulfate and balance a battery bank in systems which are deficit cycled and/or charged at lower charge currents.

Can a sulphated battery be equalized?

Equalization must be time limited. Some cells can experience excessive overvoltage and cause permanent battery damage The equalization process only works on lightly sulphated plates. It will not work for heavily sulphated plates To eliminate the normal, mild sulphation resulting from discharge, an equalization routine is performed.

When is a corrective equalization necessary?

Typically, a corrective Equalization is necessary every 60 to 180 days to desulfate and balance a battery bank in systems which are deficit cycled and/or charged at lower charge currents. If multiple parallel strings show charge imbalance it may be necessary to equalize each string individually.

How long does a corrective equalization last?

Some systems offer a scheduled or automatic preventative equalization. These may be scheduled to run for 1-2 hours to balance and remove any buildup of sulfation that has accumulated between corrective equalizations. Corrective Equalizations should be performed when the battery bank is at 100% SOC.

How do I test a Rolls FS battery?

Rolls FS models are shipped with electrolyte reaching 1.280 at full charge. This is noted on the battery label. Procedure: 1. Complete a Bulk & Absorption charge to bring the battery bank to 100% SOC before starting a corrective Equalization. 2. Measure the temperature of a test cell and record the specific gravity of each cell in the battery bank.

Does the equalization process work on sulphated plates?

The equalization process only works on lightly sulphated plates. It will not work for heavily sulphated plates To eliminate the normal, mild sulphation resulting from discharge, an equalization routine is performed. A slight overcharge is applied to insure the lowest cell voltage is at least 2.5 volts.
