Deep-Cycle Batteries
Deep-cycle batteries are designed for deep discharge service where they
will be repeatedly discharged and recharged. They are marketed for use in
recreational vehicles, boats, and electric golf carts—so you may see them
referred to as RV batteries, marine batteries, or golf cart batteries.
For most applications of the Duracell, we recommend that you use one or
more deep-cycle batteries that are separated from the vehicle’s starting
battery by a battery isolator.
A battery isolator is a solid-state electronic circuit that allows equipment
to be operated from an auxiliary battery without danger of discharging the
vehicle’s starting battery. During vehicle operation, the battery isolator
automatically directs the charge from the alternator to the battery
requiring the charge. Figure 3-1, “Configuration for Normal Loads” on
page 3–2 and Figure 3-2, “Configuration for Heavy Loads” on page 3–3
show a battery isolator in configurations for normal and heavy-duty loads.
Battery isolators are available at marine and RV dealers and most auto
parts stores.
Battery Size
Battery size or capacity is as important as the battery type for efficient
operation of your loads. We recommend that you purchase as much
battery capacity as possible.
A number of different standards are used to rate battery energy storage
capacity. Automotive and marine starting batteries are normally rated in
cranking amps. This is not a relevant rating for continuous loads like an
inverter. Deep-cycle batteries use a more suitable rating system, either
“amp-hours” (“Ah”) or “reserve capacity” in minutes.
CAUTION
The Duracell must only be connected to batteries with a nominal output voltage
of 12 volts. The Duracell will not operate from a 6 volt battery and will be
damaged if connected to a 24 volt battery.
