should be applied as follows for a 10-minute period:

If a high- rate charger is not available, charge at 15

amperes for 30 minutes.

REMOVA L AND INSTALLATION

Selecting the Size

Batteries sold for replacement should be of an

electrical size at least equal to battery placed in vehicle

by the manufacturer.

Frequently additional current-

consuming devices have been added to the vehicle by

the owner, which may make a larger capacity battery

desirable.

Also the drain on battery may be very high when

engine is not running.

High capacity alternators or

generators carry the electrical load when the engine is

running, but too small a battery may be discharged so

much by lights and miscellaneous current draws while

parked that cold weather starting is seriously impaired

before the driving time allows the generator to restore

the charge to the battery.

A larger battery will also have

longer life and, therefore, be a worthwhile investment.

Make sure larger battery will fit the application.

Removing Old Battery

When removing old battery note the location of

positive terminal so that new battery is installed in the

same manner.

Remove "ground" terminal first.
