Visual check
CAUTION:
The battery plugs must be fully tightened when charging, measuring voltage or performing load tests.
A visual check of the battery should be performed before performing measurements such as resting voltage, electrolyte density or battery load check.
Performing this test establishes:
- Whether battery housing is damaged. Electrolyte can leak out if housing is damaged.
- Whether battery posts (battery cable connections) are damaged. Wiring connector contact cannot be guaranteed if battery post is damaged. This may cause a cable to spark/burn which may cause malfunctions in electrical system.
