BATTERIES
set voltage reaches .5 volts above the shut-off point (42.0 volts), use a multimeter to measure individual battery volt-
ages. Measure and record the voltage of each battery to the nearest .01 volt.
NOTE
• THE TESTER WILL SHUT OFF AUTOMATICALLY WHEN SHUT-OFF VOLTAGE IS REACHED.
Interpreting Discharge Test Results
1. If discharge time is 60 minutes or higher, the problem is not with the batteries.
2. If discharge times are low, compare individual battery voltages recorded in step 5. If any battery shows a 0.4
volt or greater variance, the battery is defective or nearing the end of its useful life and should be discarded or
grouped with other batteries at or around same voltage. The voltage of a defective battery will drop more
rapidly near the end of the discharge than that of a sound battery.

7.07 7.07
7.20 7.20
3. If all the batteries are within 0.30 volts of each other, but the discharge time is low, the batteries are approaching
the end of their life and the whole set will have to be replaced. In general, vehicles that discharge in less than 60
minutes at 78° F on the discharge test will typically not hold a charge for an entire work shift. However, discharge
time is dependent on the electrolyte temperature. The table shown gives the discharge times, at various tempera-
tures, of a set of batteries that delivers 62 minutes at 80°F.
