Equalizing Flooded Batteries
About Equalizing
The XC S eries equalizes only flooded lead-acid or lead-calcium batteries. It does
not equalize sealed lead-acid batteries since they can be damaged by this process.
In the following conditions the remote display will show and the XC Series will
not enter equalization mode:
• the battery type is set for Gel or AGM
• any battery is not fully charged (all three battery banks must be charged to float
or rest stage before equalization can be activated on any bank)
• there is an active fault on the battery you are trying to charge
Xantrex recommends that you run a normal charge cycle on the batteries be fore you
equalize them.

WARNING: Explosion hazard

During equalization, the battery generates explosive gases. Follow all the battery safety
precautions listed in this guide. V entilate the area around the battery thoroughly and ensure
that there are no sources of fl ame or sparks in the vicinity

CAUTION: Risk of battery damage

The XCSeries cannot automatically determine when to stop the equalization of a battery.
You must monitor the battery specific gr avity throughout equalization to determine the end
of the equalize cycle. The one hour time-out is intended as a safety feature to require the
user to continually re-activate it as necessary after checking batteries manually, but may not
be sufficiently short to prevent battery damage.
