6.2.3Vehicle Battery Charger
a)The vehicle battery charger supplied with the SD2100v2 will charge the detector battery from the cigarette lighter socket of a motor vehicle.
b)Plug the vehicle battery charger into the cigarette lighter socket and turn the vehicle ignition switch to ‘Accessories’ to supply 12 volt power to the cigarette lighter socket. This voltage is reduced by the vehicle battery charger to 6 volt output to charge the detector battery.
c)If the battery voltage of the vehicle drops below 11 volts the charger will stop charging. This prevents the battery charger from flattening the vehicle battery.
CAUTION 
The charger is designed for use with vehicles with a negative earth electrical system (i.e. most cars made after 1970). If you plug the charger into a vehicle with a positive earth system, the fuse in the cigarette lighter socket will blow and the LED will not light.
