Battery Load Test, Performing

Battery load test indicates battery condition.

Special tools, testers and auxiliary items required

• Battery Tester (VAS 5097 A)





• If (VAS 5097A) is used, it is not necessary to remove battery. The battery does not need to be disconnected either.

- Switch ignition off.

- Read battery tester operating instructions.

- Connect test lead clamps to battery terminals as shown in battery tester operating instructions.

The clamps must make good contact with battery poles.

- Load current depends on battery capacity and must be adjusted on the tester => battery tester operating instructions.

- Perform battery load test according to operating instructions.

Note following tester evaluations:





1) After recharging the battery, again perform a battery load test. After recharging, "Battery good" is displayed. End the procedure. If "Battery bad" is shown, replace it.
2) Replace battery with customer's approval.

- Replace battery.

Regarding battery load test:

Because of the high load on the battery during this test (a high current flows) the battery voltage lowers.

If the battery is OK, the voltage only goes down to the minimum voltage specification.

If the battery is faulty or not charged enough, the battery voltage drops quickly below the minimum voltage specification.

After the test, this low voltage remains steady over a longer time before the voltage slowly increases.
