3. Turn the discharge machine on and record the voltage reading of battery pack while under load.
4. A fully charged set of batteries in good condition should read between 46-49 volts while under load.
5. A reading of 32-46 volts indicates discharged or failed batteries. Each battery should be checked with a
multimeter while under load.
6. A reading of 32 volts or less will not activate discharge machine. If the voltage of the batteries is below 32 volts,
the batteries are deeply discharged or have failed.
7. Recording the battery pack voltage reading while under load provides a more accurate diagnosis of the condition
of the batteries. When the discharge machine is ON, it places the battery pack under load and many times
can help determine if one or more batteries in the set have failed. Testing battery voltage while the batteries
are not under load will not always indicate the true condition of the batteries. For more information about the
batteries, refer to Section 16 — Batteries .
