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, charging voltage, or charging time is 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.

These battery chargers test whether the 12-V battery
retains its voltage. It is also impossible to overcharge
the 12-V battery with these battery chargers. The
charging time may be longer at low temperatures.
These battery chargers are only suitable for lithium iron
phosphate batteries. Read the accompanying KTM Pow-
erParts instructions.
