General Battery Information
_ WARNING!
, Should battery acid accidentally splatter into
the eyes or onto the skin, rinse the affected area
immediately with clean cold water. If there is any
further discomfort, seek prompt medical attention.
If acid spills on clothing, first dilute it with
clean water, then neutralize with a solution of
ammonia/water or baking soda/water.
NEVER connect (or disconnect) battery
charger clips to the battery while the charger is
turned on, as it can cause sparks.
Keep all sources of ignition (cigarettes,
