ELECTRICAL SYSTEM 15

Info
Even when there is no load on the 12-V battery, it discharges steadily each day.
The charging level and the method of charging are very important for the service life of the 12-V battery.
Rapid recharging with a high charging current shortens the service life of the battery.
If the charging current or charging voltage are exceeded, the 12-V battery will be destroyed.
If the 12-V battery is depleted by repeated starting, the 12-V battery must be charged immediately.
If the 12-V battery is left in a discharged state for an extended period, it will become deeply discharged
and suffer a loss of capacity, destroying the battery.
The 12-V battery is maintenance-free.
