CAUTION!
• It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked (+)
positive and negative (-) and identified on the
battery case.
• If a "fast charger" is used while battery is in
vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a "fast charger" to provide starting voltage.

Maintenance Free Batteries (Diesel Engines)

The top of the maintenance free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE: Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's charging
system.
