Equalizing (flooded/wet batteries ONLY)
3.4.2.
Equalizing is an overcharge performed on flooded/wet batteries after they have
been fully charged. Trojan recommends equalizing only when batteries have low
specific gravity, below 1.250 or wide ranging specific gravity, 0.030, after fully
charging a battery. Gel or AGM batteries should never be equalized.
•
Confirm that the batteries are flooded/wet
•
Check electrolyte level to make sure plates are covered with water before
charging
•
Check that all vent caps are secured properly on the battery before charging
•
Set charger to equalizing mode
•
The batteries will gas (bubble) during the equalization process
•
Measure the specific gravity every hour. Discontinue the equalization charge
when the gravity no longer rises
WARNING: Do not equalize gel or AGM batteries.
4.
Storage
•
Charge battery before placing in storage
•
Store in a cool, dry location, protected from the elements
•
Disconnect from equipment to eliminate potential parasitic loads that may discharge the
battery
•
Batteries gradually self-discharge during storage. Monitor the specific gravity or voltage
every 4-6 weeks. Stored batteries should be given a boost charge when they are at
70% state of charge (SOC) or less. Refer to
measurements
•
When batteries are taken out of storage, recharge before use
