BATTERY TYPES
Use only deep-cycle batteries with your
FP3000-12. 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 internal plates
that are alloyed with antimony.
Common 12-volt marine/RV deep-cycle
batteries are acceptable. Golf cart
batteries perform well and may have a
longer life. These 6-volt batteries must be
used in series connected in pairs. High
quality deep-cycle batteries offer good
performance and are available in a wide
variety of sizes.
Wet cell 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 necessary.
Follow the battery manufacturer’s
recommendations for maintenance.
Never allow the top of the battery plates to be
exposed to air, as contamination of the cell will
result. Keep the top of batteries clean. Always
provide adequate ventilation for the battery
storage compartment.
Do not use ordinary car batteries or engine
starting batteries 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 type batteries, suitable for
either engine starting or deep-cycle applications,
are a compromise and will have limited life if
deeply discharged.
