marine/RV-deep cycle batteries. This information
is designed to
clarify terminology and
misconceptions and to assist

Deep
Cycle Batteries
The term "deep cycle" refers, in
general, to a battery which has the capability
of deeply discharging hundreds of times. How
does it differ from other batteries? An
automotive starting battery is manufactured
specifically to provide a quick burst of energy
thousands of times in its lifetime while only
being able to deeply discharge less than
50 cycles during its life.
|
Proper
Deep Cycle Application
A marine/RV-deep cycle battery can be used for
various applications including boats, motor
homes, sail boats, travel trailers, tent
campers, etc. Anytime an application indicates a
need for batteries which can provide repeated
deep discharge, you need marine/RV-deep cycle
batteries.
|
What
is a Cycle?
A cycle refers to one battery discharge
and recharge of any depth. The amount of battery
discharge (in percent) compared to its full
capacity determines the need for a shallow,
moderate or deep cycle. This is appropriately
called battery depth of discharge (DOD) and is
measured in percent. For example, 40% DOD
indicates a battery has been discharged by 40%
of its total capacity and has a 60% state of
charge remaining. |
Types of Cycles
There are three primary types of battery discharge cycles:
shallow, moderate and deep. These
terms help us to understand the type of cycling that
batteries are required to experience. To clarify, let's
take a look at all three types. Shallow cycles
occur when only a small percent of the total battery
capacity is discharged. Following that same line of
thought, moderate or deep cycles are
discharged by a higher percent of the total battery's
capacity.
What Makes Deep Cycle
Batteries Distinctive?
Several qualities separate deep cycle batteries from
starting types: thicker plates, denser active chemical
plate material and a specially formulated grid alloy.
These and other added features allow the Interstate
marine/RV-deep cycle batteries to withstand the severe,
repeated stress that deep cycling creates. Two of the
newest features are the Na2SO4
additive to the electrolyte and the Negative Plate
Expander.
