4. DETAILED OPERATING INSTRUCTIONS
4.3 PREPARATION FOR TESTING
Before starting the discharge test, read the component maintenance manual (CMM) or
the operating and maintenance manual (OMM) for the specific battery to be tested.
Ensure that the discharge rate and cutoff voltage from the battery manufacturer are
followed.
It is recommended that a visual inspection of the battery is carried out in conjunction
with testing and charging batteries.
The battery must be fully charged before testing starts, except for special tests.
WARNING: Always turn off the AC power switch before
connecting or disconnecting a battery.
NOTE: The test, unless otherwise specified in the
manufacturer's CMM/OMM, shall be conducted at room
ambient temperature of 70°F to 85°F (21°C to 29°C).
