DANGER!
Never allow an open flame or electric sparks near the
battery or batteries. Never smoke in proximity to the
batteries. The batteries give off hydrogen gas during
charging which, when mixed with air, can form an
explosive gas. This gas is easily ignited and highly
volatile.
WARNING!
Battery electrolyte is a corrosive acid and should be
handled with care. If you spill or splash electrolyte on
any part of the body, immediately flush the exposed
area with liberal amounts of water and seek medical
attention as soon as possible.
WARNING!
Risk of explosion.
Always insure the negative (-) and positive (+) battery
cables are installed on the corresponding battery post.
Incorrect connections may spark,
Do not disturb battery connections during engine start.
Ventilate the engine compartment before working on
batteries or battery connections.
WARNING!
Risk of explosion.
To prevent accidental sparks and control acid and
gases emitted by the batteries, the batteries should
always be mounted in approved marine battery boxes
with covers. Always make sure the battery is secured
and the cover is firmly attached.
NOTICE! Do not disconnect the batteries with the
engine running as sensitive electrical components may
be immediately damaged.
NOTICE! Do not use wing nuts to secure battery
cables, even if they were supplied with the battery; use
a lock nut instead.
NOTICE! When replacing your battery, read and
understand the information supplied with it before you
begin installation.
The service life of your battery depends largely on how
it is maintained.
• Keep batteries and battery terminals dry and clean.
