Equalizing Flooded Batteries

RISK OF BATTERY DAMAGE

The Truecharge2 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.

Failure to follow these instructions can damage the unit and/or damage other equipment.

In the following conditions the Truecharge2 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)1

•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.

RISK OF BATTERY DAMAGE

You must monitor the battery specific gravity throughout equalization to determine the end of the equalize cycle.

Failure to follow these instructions can damage the unit and/or damage other equipment.

The Truecharge2 Battery Charger cannot automatically determine when to stop the equalization of a battery. 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.

EXPLOSION HAZARD

•The battery generates explosive gases during equalization. Follow all of the battery safety precautions listed in this guide.

•Ventilate the area around the battery thoroughly using ventilators with brushless motors and ensure that there are no sources of flame or sparks in the vicinity.

Failure to follow these instructions will result in death or serious injury.

1.In this case an equalization cycle can be programmed to start once the charge cycle is done.
