(4) Check on battery specific gravity.
If battery is likely to be discharged due to failure in startup of the engine, measure the
specific gravity of battery acid.
The relation between- battery charge condition (charging rate) and specific gravity is as
shown below.

Each value has a deviation of ± 0.01.
When the charging rate is below 75%, the battery needs to be recharged.
