Equalizing Flooded Batteries
About Equalization
In the following conditions the Truecharge™ 2 Battery
Charger will not enter equalization mode:
• the battery type is set to 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 complete normal charge
cycle on the batteries before you equalize them.
CAUTION: Risk of battery damage
The Truecharge™ 2 Battery Charger will only equalize flooded
lead-acid or lead-calcium batteries. It does not enter equalization
when the battery type is set to sealed lead-acid batteries (GEL or
AGM) since they will be damaged by this process. Use the correct
settings for your battery types.
WARNING: Explosion hazard
During equalization, the battery generates explosive gases. Follow
all the battery safety precautions listed in this guide. Ventilate the
area around the battery using ventilators with brushless motors
thoroughly and ensure that there are no sources of flame or sparks
in the vicinity.
CAUTION: Risk of battery damage
The Truecharge™ 2 Battery Charger cannot automatically
determine when to stop the equalization of a battery. You must
monitor the battery specific gravity 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.
