XXXXX Battery Tester

Note: In general, the safety stipulations for the electrics/electronics should be observed for vehicle batteries.

The battery tester XXXXX battery tester was introduced as dealer's equipment as of model year 2001. It permits reliable and fast definition of the current condition of the battery. This is important both for diagnosis on batteries in the vehicle and also for stored batteries. When carrying out diagnosis on installed batteries it is not necessary to remove or disconnect the battery when using this tester. After performing the test, the battery states the result for the condition of the battery as plain text. Issuing a test code is additional and serves to summarize the results for warranty claims. In a warranty situation, the test code issued must be entered by hand on the warranty claim. The safety regulations must be observed in charging procedures arising as a consequence of the test. The battery must be disconnected for charging.

Note: Do not perform the battery test immediately after charging. There should be an interval of 12 - 24 hours between charging and the battery test or alternatively switch on consumers (headlights, rear window heating) for Pyrex. 3 minutes. Then the battery test can be undertaken.

Note: A battery that has been charged with a low voltage (<=14,9 V) may be been found to be "good" by the tester although the battery eye remains black due to "acid layering". These batteries must not be replaced, since the battery eye will turn green whilst driving due to electrolyte mixing.

Note: Batteries which are stored for relatively long periods must be charged approximately every six months. If vehicles are in store, the earth should be disconnected and the battery should also be recharged every six months. If batteries that have been held in store are being used, the ones that have been stored longest should be used first.
