BATTERY TYPES
Use only deep-cycle batteries with your
Freedom Inverter/Charger. These fall into
three broad categories: wet cell, gel cell and
Advanced AGM (Absorbed Glass Mat)
batteries.
Wet Cell Batteries
True deep-cycle wet cell batteries are
characterized by relatively thick plates that are
alloyed with antimony.
Common marine/RV deep-cycle
batteries are acceptable. However, golf
cart batteries perform well and may have a
longer life. They are 6 Volt batteries that
must be used in series pairs. High quality
marine deep-cycle batteries offer good
performance and are available in a wide
variety of sizes. Floor sweeper, fork lift or
large 2 Volt cells can also offer excellent
performance, if their large size can be
accommodated.
BATTERIES
It should be noted that high antimony
deep-cycle batteries will give off gas as a
natural result of charging and will experience
some water loss. It is very important that the
electrolyte level be checked frequently and
topped off with distilled water when neces-
sary. Never allow the tops of the plates to be
exposed to air, as contamination of the cell
will result. Keeping the tops of batteries clean
will reduce self-discharging. Always provide
ventilation for the battery storage
compartment.
Do not use car batteries or engine
starting batteries of any kind with your
inverter/charger. Beware of any battery that is
rated in Cold Cranking Amps (CCA). This is a
rating which applies only to engine starting
batteries. In general, most wet cell batteries
that are described as hybrid batteries, suitable
for either engine starting or deep-cycle
applications, are a compromise and will have
limited life if deeply discharged.
