Visual Check



Visual check

Carry out a visual check of the battery before performing measurements such as no load voltage, electrolyte specific gravities or battery load test.


Notes: Performing this test establishes:

- Whether the battery housing is damaged. Electrolyte can leak out if the housing is damaged.

- Whether the battery terminals (battery wire connections) are damaged. Wiring 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.
