VIII) BATTERY CARE TIPS

5.5
Regular maintenance and proper care will assure you reliable
service from the most depended upon and sometimes most
neglected items, your batteries and battery charger. NEWMAR
battery chargers are designed to keep your batteries fully charged
but your batteries also need proper regular maintenance to
provide a maximum life of service.

Battery Installation
Batteries must be securely mounted to prevent them from falling
over when the vehicle or boat is in motion. A loose battery can
do serious damage. Batteries should be mounted in a battery
box to contain any acid spill. Batteries give off a certain amount
of hydrogen gas when they are charging. When concentrated,
this gas is highly explosive. Therefore make sure they are in an
accessible place with adequate ventilation for any hydrogen gas
discharge.
Cleaning Batteries
Dirt and electrolyte salts can build up on the top of your batteries.
This accumulation conducts electricity stored in the battery and
can cause the battery to discharge by itself. Therefore, at least
twice a year, it is a good idea to disconnect the battery cables
and scrub the battery with a baking soda solution. Rinse with fresh
water and dry with a clean cloth.
You may wish to purchase a set of terminal post corrosion
prevention rings. These are alkali-saturated felt rings that slip over
the battery post to reduce corrosion. Do not apply grease to any
part of the battery terminals, but you may use an occasional light
spray of silicone lubricant.
