alloyed with the lead and hold the liquid
electrolyte in a sponge-like material. They are
sealed and water can not be added. Do not
confuse them with true gel cell or AGM
batteries, they will not hold up well to deep
discharging and repeated cycling.

Gel Cell Batteries

Gel Cell Batteries Gel Cell Batteries Gel Cell Batteries Gel Cell Batteries
Gel cell batteries are lead-acid batteries
similar in many ways to the common wet cell
battery, b u t d i fferences in the chemistry and
construction provide some unique features.
• No Maintenance
• Low Self-Discharge Rate
• Low Internal Resistance
Even though gel cells are sealed
batteries, the battery compartment should still
be ventilated.

Battery Selection

Battery Selection Battery Selection Battery Selection Battery Selection
The most important feature to consider in
making your battery selection is to select true
deep cycle batteries rated in Amp-hours (AH)
and sized to match your power requirements.

In most cases, you will be using a bank of
two or more batteries with your inverter/
charger. You may connect batteries together in
two configurations, series and parallel
depending on their voltage.

Connecting two batteries in series will
double the voltage of the battery bank. For
instance, two 6 volt batteries connected in
series will produce 12 volts. The Amp-hour
capacity of the battery bank will be the same
as each individual battery. Example, two 6 volt
220 Amp-hour batteries in series will produce
one 12 volt 220 Amp-hour battery bank.
