Battery
Batteries in Cold Weather
In colder weather, a greater drain is placed on the batteries
when they are used for the preheat cycle and when starting a
cold engine. Battery performance decreases as the temperature
gets lower.
In extremely cold weather, remove batteries at night and move
them to a warm location. This will help to keep them at a higher
energy level.
WARNING
AVOID DEATH OR SERIOUS INJURY
Battery electrolyte contains sulfuric acid and can quickly
burn the skin and eat holes in clothing. If you spill acid on
yourself, immediately flush the area with water.
Battery acid could cause blindness if splashed into the
eyes. If acid gets into the eyes, flush them immediately with
large quantities of water and seek professional medical
attention immediately.
If you accidentally ingest acid, call a doctor or poison
prevention center immediately.
When working with batteries, always wear safety goggles.
Battery generates hydrogen gas, so there is a danger of an
explosion. Do not smoke near batteries, or do anything that
will cause sparks.
Before working with batteries, stop engine and turn the
starter switch to "O" (OFF) position.
Avoid short-circuiting the battery terminals through
accidental contact with metallic objects, such as tools.
When removing or installing, check which is the positive (+)
terminal and negative (-) terminal.
When removing the battery, first disconnect the negative (-)
terminal. When installing the battery, first connect the
positive (+) terminal.
If the terminals are loose, there is a danger that defective
contact may generate sparks that will cause an explosion.
When installing the terminals, install them tightly.
