Range Rover L322 Battery System Description and Operation
CHARGING AND STARTING
86-1-8
DESCRIPTION AND OPERATION
The battery incorporates an integral, temperature compensated hydrometer to provide a visual indication of the
relative density and level of the electrolyte. The indicator shows different colours to show battery condition as follows:
l
GREEN – shows that the battery is charged and in a serviceable condition
l
DARK (turning to black) – shows that the battery is in a low state of charge and requires recharging
l
CLEAR or YELLOW – the battery is no longer serviceable and must be replaced.
If the battery shows CLEAR or YELLOW the battery has an internal fault. Do not attempt to charge or jump start the
vehicle with the battery in this condition.
When removing the battery, ensure that the alarm is disarmed and that the ignition is switched off. Always disconnect
the negative terminal first and then the positive terminal. When refitting the battery, always fit the positive terminal first
followed by the negative terminal.
If the battery requires recharging, always use an approved constant current charger, designed for lead-calcium
batteries. DO NOT use a fast charger, permanent damage to the battery may occur.
During production of the vehicle a transportation cut-off switch is connected in series between the battery negative
terminal and the battery ground cable, to minimise battery drain during vehicle storage and delivery. The
transportation cut-off switch provides a convenient method of disconnecting power from all of the electrical systems
on the vehicle, but allows power to be easily restored to start and drive the vehicle during loading and unloading.
Operating the transportation cut-off switch generates fault codes in some system diagnostics. The fault codes are
cleared, and the transportation cut-off switch is removed, during the Pre Delivery Inspection (PDI), prior to handover
of the vehicle to the customer.
