6. Battery Voltage Checking: Overview

Battery voltage is checked with a voltmeter between battery plus and minus pole. The following points should be observed before measuring to receive definite and valid measuring values:

- Minimum resting times must be observed after load testing or charging to obtain the actual battery voltage. The measured value will not correspond to the actual charging condition if resting times are not observed.

Resting Times:
2 hours after battery charging (minimum) (8 hours even better)
1 hour after loading (engine start load testing)

- The battery must be disconnected when measuring. If necessary, voltage can be checked at the cigarette lighter plug. However, accuracy is not very high because of the constant current draw influences.





- Determine approximate battery temperature. The battery temperature equals ambient temperature if the battery was stored for at least 12 hours in an area with approximate constant ambient temperatures. (See evaluation table.)
