tomotive
charger
will extend
its life.
• Keep battery
and terminals
clean.
• Keep battery
bolts tight.
• Keep small vent holes
open.

at 6-10 amperes
for 1 hour.

The
original
equipment
battery
on
your

not
attempt
to open or remove
caps or covers.
Adding
or checking
level
of electrolyte
is
not necessary.
