COMMISSIONING LOG BOOK
12.3 E3 Battery Capacity Test
This test may be performed away from the system.
Disconnect the system batteries and replace with substitute batteries.
Discharge the system batteries at current of Idis , the formulae for the calculation of Idis can be
found in section 6 ( record the value in section 6 ).
Measure the voltage across the battery terminals. Discharge the batteries until the voltage across
them reaches the discharged terminal voltage obtained from the battery manufacturer (this should
also be recorded in Section 6) Record the time taken to reach this voltage in the log book. If the time
taken is less than 30 mins take any necessary corrective action.
Recharge the system batteries to a capacity greater than 95% of maximum using a battery charger,
the system should not be used to achieve this.
Remove substitute batteries from the system and replace with the system batteries.
