6.2.3 Vehicle 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
When using the mains charger:
DO NOT leave partially discharged batteries charging overnight,
and
DO NOT leave the mains charger on for extended periods of time
as reduced battery life can
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.
