PLACING NEW BATTERIES INTO SERVICE
1.
When replacing a battery or set of batteries with a fresh new battery(s); before they are installed or the vehicle
is operated, the batteries should be charged (topped off) until the Open Circuit Voltage (OCV) reaches >12.65
VDC and the amperage meter on charger reads < 1 amp for one hour. For best results, allow batteries to
charge overnight. Follow procedures in (WP 0007, 0008, 0009) as applicable.
2.
If replacing one battery in a string of batteries, it is best to replace with a used battery that has been recharged,
or to replace all batteries in the string with new ones and redistribute the used serviceable batteries. Battery
should be tested and charged (topped off) to ensure the OCV is > 12.85 VDC upon installation.

PLACING USED BATTERIES INTO SERVICE
1.
When replacing a battery or set of batteries with a used battery(s); before they are installed or the vehicle is
operated, the batteries should be charged (topped off) until the OCV reaches > 12.65 VDC and the amperage
meter on charger reads < 1 amp for one hour. For best results, allow batteries to charge overnight. Follow
procedures in (WP 0007, 0008, 0009) as applicable.
2.
If replacing one battery in a string of batteries, it is best to replace with a used battery of similar age that has
been recharged, or to replace all batteries in the string with new ones and redistribute the used serviceable
batteries. Used battery should be tested and charged (topped off) to ensure the OCV is > 12.65 VDC upon
installation.
3.
Good used batteries will recharge to voltages > 12.85 VDC but after an eight hour rest period should stabilize
> 12.65 VDC. They should also have a CCA rating > than 90% of CCA rating shown on battery, when tested
with a battery analyzer i.e. PT490.
