GENERAL
The batteries for 1982 Jeep vehicles are lightweight
and have low-antimony/lead compound plates. In addi
tion to helping reduce overall vehicle weight, they re
quire less frequent electrolyte level inspections, have a
decreased self-discharge rate from local action and have
a longer shelf life. Electrolyte level inspections are re
quired only at the beginning of each winter season and
every 15,000 miles (24 000 km).
In addition to the standard equipment 380 cold crank
amps battery, a 450 cold crank amps battery is option
ally available for vehicles equipped with heavy-duty
equipment. Both batteries are 12-volt, lead-acid units.
The vehicle battery tray has a removable spacer that,
when removed, will permit the installation of a sub
stitute conventional size group 24 battery in the event a
lightweight replacement battery is not available.
NOTE: A UO Cold Crank Amps with 135-Minute Re
serve Capacity is optionally available for 1982 J-Series
vehicles equipped with a Police Package.

Reserve Capacity Minutes Rating
Reserve capacity minutes is defined as the number of
minutes a fully charged battery at 80°F (26.7°C) can be
discharged at a steady 25 ampere rate until a terminal
voltage equivalent to 1.75 volts per cell (10.50 volts total
battery voltage) is indicated. The reserve capacity rating
for each Jeep battery is either listed on a label or
stamped into the battery case. The batteries are also
color coded to denote the rating.
Cold Crank Amps Rating
The cold crank amps rating specifies the minimum
amps a fully charged battery can deliver at 0°F (-17.7CC)
for thirty seconds without the battery terminal voltage
dropping below 7.2 volts. The cold crank amps rating is
either listed on a label or stamped in the battery case.
