Whenever vehicle is not used for a period of three
months or more, remove the battery from the vehicle, CAUTION

To perform this test, use a load testing device that has an
adjustable load. Apply a load of three times the ampere-

BATTERY TESTING voltage. A good 12V battery will have at least 10.5 volts.
If the reading is low, charge the battery and retest.
Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.

NOTICE
Maintenance Free batteries should be kept at a high
state of charge during storage. If the battery is stored or
used at a low state of charge, hard crystal sulfation will
form on the plates, reducing the efficiency and service
life of the battery.
Use a volt/ohm meter to test battery voltage.
