Battery inspection
Check each element with a hydrometer.
Specific gravity: 1,270 ÷ 1,290 at 20°C.
If the specific gravity is under 1,230 the battery must be charged; specific
gravity varies according to temperature.
Replace battery if there is sulfation and if the space between the plates is full
of sediments.
Note:
The battery’s electrolyte contains sulphuric acid.
