ELECTRICAL
OCV - Open Circuit Voltage Test
Battery voltage should be checked with a digital multitester.
Readings of 12.6 volts or less require further battery testing and
charging. See the following chart and "Load Test".
NOTE: 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.
NOTE: Use a volt/ohm meter to test battery voltage.

CAUTION
To prevent shock or component damage, remove spark
plug high tension leads and connect securely to
engine ground before proceeding.
A battery may indicate a full charge condition in the OCV test,
but still may not have the storage capacity necessary to properly
function in the electrical system. For this reason, a battery
capacity or load test should be conducted whenever poor battery
performance is encountered.
To perform this test, use a load testing device that has an
adjustable load. Apply a load of three times the ampere-hour
rating. At 14 seconds into the test, check battery voltage. A
good 12V battery will have at least 10.5 volts. If the reading is
low, charge the battery and retest.

Charging Procedure

If battery voltage is 12.6 Vdc or less, the battery may need
recharging. When using an automatic charger, refer to the
charger manufacturer's instructions for recharging.
Do not exceed 10 amps when charging the 4011224 battery.
NOTE: Charge the battery using an automatic
charger that will not exceed 14.6 Vdc. An automatic
charger will signal when charging is complete.
NOTE: Allow the battery to stand disconnected for
several hours after being properly charged. If the
voltage drops below 12.6 volts, charging was
ineffective or the battery needs to be replaced.
WARNING
An overheated battery could explode, causing severe
injury or death. Always watch charging times carefully.
Stop charging if the battery becomes very warm to the
touch. Allow it to cool before resuming charging.
