Refer also to program P321: Capacity Test.
The program Capacity Test involves only the discharge with capacity test!
Enter:
 Number of cells
 Rated capacity
 Query, when the cell test measurement should be taken (80 - 100% or 48 - 60 minutes)
 Query, if the manufacturer's recommended procedure or a fast maintenance
A) The recommended procedure of Hawker extends battery life and ensures maximum life-
span.
B) Fast maintenance can be applied to temporal bottlenecks, if any repairs on the battery are
required and the battery has met the requirements of the insulation test (> 0.5 MΩ).
A) Recommended procedure:
Step 1:
Discharging with C
1
until a voltage of 1 V for each cell is reached.
Step 2:
8 hours break.
The message is displayed:
„wait 8 hours. to skip waiting time: press .“
Step 3:
I-Charge with C
1
until charging voltage of 1.55 V × number of cells is reached.
Step 4:
Topping charge with C
5
for 2 hours.
In case no automatic cell tester is connected:
15 minutes before the end of the topping charge a signal requests for measurement of single cells
voltages and to control the electrolyte level.
Otherwise:
Cell measurement is performed automatically und you are asked to control the electrolyte level.
In case that step 1 has been completed with a capacity rated above the nominal capacity, the pro-
gram ends with this step.
