ELECTRICAL FEATURES CONTINUED
BATTERY INSPECTION AND CARE
The motorhome batteries which constitute the
12VDC system are located inside the motorhome
entrance step well (Figure 77.1).
To access these batteries, open the access panel on
the steps (Figure 77.2). When access to the
batteries is no longer needed, close and securely
fasten the access cover to place these steps back
into service.
When batteries are not used for an extended period
of time, they will gradually lose their optimal
electrical charge. Therefore it is necessary to
periodically recharge the batteries to increase the
overall life of the batteries. It is also necessary to
check the external condition of the batteries on a
regular basis.
Look for cracks in the battery case and cover.
Check the vent plugs and replace them if they are
cracked or broke. Keep the batteries clean. If any
accumulation of dirt or acid residue around the
battery terminals may provide an electrical path for
battery discharge. The areas around the terminals
should be cleaned periodically.

One can use an old toothbrush and a sparse amount of of diluted solution of baking soda
(sodium bicarbonate) and water (distilled,or deionized is preferred; tap water is acceptable) to
clean and neutralize any acidic build up around the battery terminals. If there is any foaming on
the top of the battery, this indicates that acidic residues are being neutralized. Rinse the cleaned
areas thoroughly with distilled or de-ionized water (tap water is okay as well).
Dry the battery cables and terminals to prevent corrosion; to protect those terminal further, use
a plastic ignition spray on the terminals. Do not use grease on the terminals, especially on the
metal to metal connections as grease may act as an insulator and keep the battery electrical
power from entering the cables.
Motorhome batteries will either be standard AGM batteries or optional Lithium batteries as
shown in (Figure 7 7 .2).
