Equalizing Gel Cell Batteries
You don’t normally equalize gel cell batteries. If they have
been severely discharged, however, this may be the only way
to get them to begin accepting a charge. The voltage is
limited to the Acceptance charging level, but the cycle lasts
for eight hours.
Be sure that battery type is set to 002 before you equalize gel
cell batteries.
Activating Power Share
Power Share is a load management feature that helps prevent
external source AC breakers from tripping when the charger
and a number of other loads all come on at once. Power share
automatically reduces the output of the Freedom Inverter/
Charger if the AC loads exceed a specified current limit.
To change the Power Share setting:
•See page 27.
Battery Capacity Testing
To determine the actual amount of energy your batteries can
store, you conduct periodic capacity tests. A capacity test
should start with a battery that has been properly charged and
equalized.
Deep cycle battery capacity is usually stated as a 20 hour
discharge rate (a 100 Ah battery will provide 5 amps for
twenty hours). At discharge rates above 5 amps, the battery
will supply less than 100 Ah. For example, if you are drawing
100 amps out of the battery, it will last less than half an hour.
The following table shows battery capacity at various
discharge rates.
