Note
Environmental hazard 12 V batteries contain environmentally hazardous materials.
–
Do not dispose of 12 V batteries as household waste.
–
Dispose of 12 V batteries at a collection point for used batteries.
Info
Even when there is no load on the 12 V battery, it discharges steadily.
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 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.
