INTRODUCTION
With this processor controller capacity test, you can measure the C20 capacity of a 12V battery. The discharge current will
be set automatically. For batteries below 25Ah C20 capacity, the tester will select the C1 rate (e.g. for 18Ah battery it will be
18A). For batteries above 25Ah C20 capacity, the discharge current will always by 25A. The cut-off voltage (the voltage limit
where you want to stop the discharge) is set to 1.6VPC. The tester calculated the C20 capacity referring to the Peukert values
of the battery.
As a further option, you can also make a single cycle test of the battery. You can set the charging time in hours. In the menu
of the tester, you decide if you start the test with a charge or discharge cycle. Starting with a charge cycle, the battery will be
charged for the programmed period of time. The battery will then be discharged at the related C20 discharge current down
to 1.6VPC. Finally, the battery will be recharged to the programmed time, which completed the cycle.
If you program the charging time to ‘0 hours’, the battery will only be discharged.
The test results can either be displayed online on a PC screen or can be seen as a total result in the menu of the tester.
