BATTERIES
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 (less than 60 minutes), replace batteries below 6.7 volts.

3. In general, battery sets that discharge in less than 60 minutes at 78 °F (25.6 °C) 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 temperatures, of a set of batteries that
delivers 62 minutes at 80 °F (26.7 °C).
