(5) 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.
Liquid
Charging temp,
rate (%) °C
2 0
0 - 1 0
1 0 0 1. 28
1.29 1. 30
9 0
1. 26
1.27 1.28
8 0 1. 24 1.25 1.26
7 5
1.23 1. 24 1. 25
Each value has a deviation of ± 0.01.
When the charging rate is below 75%, the battery needs to be recharged.
