16. Every 200 hours:
CHECKING CHARGE
STATE IN THE BATTERIES
Note! Every 200 hours applies to gensets and the like.
Other installations every 1,200 hours.
- Check specific gravity using a battery electrolyte tester.
In a fully charged battery it should be:
1,280 at +20°C
1,294 at 0°
1,308 at -20°C
- If the specific gravity is below 1.20, the battery must be charged.
A discharged battery freezes at -5 °C.
Avoid boost charging. This will damage the battery in the long term.
