Equalizing (Flooded batteries only)


Equalizing is an overcharge performed on flooded lead acid batteries after they have been fully charged. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalizing also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery.

Many experts recommend that batteries be equalized periodically, ranging anywhere from once a month to once or twice per year. However, Trojan only recommends equalizing when low or wide ranging specific gravity (+/- .015) are detected after fully charging a battery.

Step by Step Equalizing:

1. Verify the battery(s) are flooded type.

2. Remove all loads from the batteries.

3. Connect battery charger.

4. Set charger for the equalizing voltage (See Table 2 in the Charging section).

5. Start charging batteries.

6. Batteries will begin gassing and bubbling vigorously.

7. Take specific gravity readings every hour.

8. Equalization is complete when specific gravity values no longer rise during the gassing stage.

NOTE: Many chargers do not have an equalization setting so this procedure can't be carried out.
