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).

BATTERY TROUBLESHOOTING EXAMPLES
The following information represents a few examples of troubleshooting battery problems.
Example 1
Vehicle no. 68 was suspected of having a bad battery due to its performance. As a result, the battery charger test
was performed. After a full charge, the battery charger ammeter read 8.0 amps. Next, the on-charge voltage test
was performed and the following results were recorded:
BATTERY NO. 1 2 3 4 5 6 7 8
On-Charge Voltage 7.40 V 7.60 V 7.10* V 7.40 V 7.70 V 7.80 V 7.80 V 7.80 V
*Battery no. 3 appears suspect. Batteries no. 1 and 4 are also suspect. Next, a hydrometer test should be conducted
on all batteries.
Hydrometer test results:

Cell 1 (Positive Post) 1.200* 1.265 1.300 1.250 1.280 1.260 1.260 1.260
Cell 2 1.285 1.275 1.290 1.270 1.295 1.265 1.265 1.265
Cell 3 (Negative Post) 1.265 1.270 1.275 1.265 1.280 1.275 1.275 1.275
*After the hydrometer test, it appears that battery no. 1 is the problem. Next, the discharge test was performed.
