Visual Check

WARNING: The battery plugs must be screwed in tightly when charging, measuring voltage or performing load tests.


Carry out visual check of the battery before performing tests, such as no-load voltage, electrolyte specific density or battery load test.

NOTE: A visual check will show:

- Whether the battery housing is damaged. Electrolyte can leak out if the housing is damaged.
- Whether the battery terminals (battery wire connections) are damaged. Reliable cable connector contact cannot be guaranteed if the battery terminal is damaged. This may cause a cable to spark or burn, which may cause malfunctions in the electrical system.
