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 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.

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.

NOTE: Follow the charger instructions supplied by
the manufacture regarding the order or connections,
switch positions and when to connect the charger to
an outlet.

Battery Testing

Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.
Following are two tests which can easily be made on a
sealed Maintenance Free battery to determine its
condition: OCV Test and a Load Test.

OCV - Open Circuit Voltage Test

Battery voltage should be checked with a digital
multimeter. 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.
