mandate items like the LP-Gas detector. If the motorhome is not going to be
used or is stored for more than 48 hours, it is recommended to turn the
batteries off.

The operation of the battery is based on a chemical reaction. The battery is
comprised of lead plates and a solution of distilled water and sulfuric acid. The
solution, when mixed together, is known as “electrolyte.” The 12 volt battery is
actually six batteries in one case. When charged, each cell has a voltage of 2.1
Volts. When six cells are hooked together this makes a 12.6 Volt battery (fully
charged).
Electrons are stored on the negative plates. When a load (eg. a light bulb) is
put between the positive and negative terminals, the electrons move from the
negative plate to the positive plate through the “load” and then back to the
ground terminal. At this time, the sulfuric acid leaves the water and adheres
onto the plates of the battery. The electrolyte solution keeps the electrons from
flowing while the battery is in the “at rest” position.
Charging the battery moves the sulfuric acid back into solution with the
distilled water. A battery left in a low or discharged state will cause the acid to
“sulphate.” In attempting to recharge the battery, the acid has become hardened
and no longer will leave the plates and enter into the liquid solution with the
distilled water. The lowered acid to water ratio has a direct affect on the bat-
tery’s ability to release the stored electrons (power output) and the length of
time it can preform(reserve capacity). Batteries left in a discharged condition
will also readily freeze. This can crack the case allowing the solution to spill, it
can also warp the plates.The acid acts like an “antifreeze” for the battery. This
is why batteries should not be left or stored in a “discharged” condition.

Batteries come in different sizes, types, amp hours, voltages and
chemistries. There are nearly as many descriptions of battery types and how
they should be used, as there are people willing to offer advice on them.
Although it is not possible to cover batteries in their entirety, there are guide-
lines that can be follow to ensure that your batteries are well maintained.

Starting batteries are designed for high output cranking power, but not for
deep cycling like the house batteries are designed to do. Starting batteries will
not last long in deep cycle application. The way they are rated should give a
good indication of their intended use. “Cold Cranking Amperes” is a measure-
ment of amperage output that can be sustained for 30 seconds. Starting batter-
ies use thin plates to maximize the surface area of the battery. This allows a
very high starting current, but lets the plates warp when the battery is deep
cycled (discharged).
