Performing An Equalization
To equalize your batteries:
1. Check the battery electrolyte level. If necessary, refill
with distilled water only. All the cells should have similar
electrolyte levels. If the levels are widely different, it will
influence the relative concentration of acid, thereby
affecting the specific gravity measurements. If distilled
water is added, batteries must undergo a complete charge
cycle.
2. Program or initiate an equalize cycle, if all banks are in
either float or rest mode.
CAUTION: Risk of equipment damage
Turn off or disconnect all DC loads on the battery during
equalization. The voltage applied to the battery during equalization
may be above safe levels for some loads but the absolute maximum
is 16 V for 12 Vdc chargers and 32 V for 24 Vdc chargers within
operational temperature range.
If this level of equalization voltage does not comply with the
battery manufacturer’s recommendation, DO NOT EQUALIZE.
WARNING: Risk of fire, burn, or explosion
Use proper precaution when working with batteries. Wear proper,
non-absorbent gloves, complete eye protection, and clothing
protection. Avoid touching your eyes and wiping your forehead
while working near batteries.
If battery acid contacts skin, wash the affected area immediately
with water. If acid enters your eye, immediately flood it with
running cold water for at least twenty minutes and get medical
attention immediately.
Important:
Remember that all connected batteries will
undergo the equalization. If only one bank is intended to undergo
equalization then the other banks must be disconnected prior to
equalization.
