WARNINGS:
To help avoid personal injury, do not use open flame, smoke, or cause an electric
spark when checking the battery, as gas generated by the battery is flammable
and can explode. Always shield your eyes and avoid leaning over the battery.
Do not ingest battery acid or fumes. If battery acid is ingested, drink large
quantities of water or milk followed by milk of magnesia, beaten egg or vegetable
oil. Call for medical assistance immediately.
Do not let battery acid come into contact with skin, eyes, hair, fabric or painted
surfaces. A solution of warm soapy water and baking soda may help neutralise
acid.
Used batteries contain sulphuric acid, lead and other potentially hazardous
materials. Dispose of unwanted batteries in authorised waste disposal facilities.
DO NOT discard unwanted batteries in household waste.
Quiescent Battery Drain
Any power drain from a battery after the ignition is switched off is referred
to as 'quiescent battery drain'. Your DB AR1, in common with many modern,
high technology motor cars, contains electronic circuits and sub-systems
which must be left activated at all times. For example, the clock, security
systems and in-car entertainment system continue to drain battery power
even with the ignition switched off. This quiescent drain will discharge a fully
charged new battery in approximately 30 days unless recharged by normal
engine running or an independent battery charger.
It is therefore vital that, when leaving your car unused for extended
periods, you use the battery disconnect switch to minimise quiescent
drain and that you use the battery conditioner to maintain battery
charge level.

The Battery Disconnect Switch
The battery disconnect switch is located in the R/H side wall trim panel of
the boot. When actuated, power to all control modules is disconnected and
only ‘keep alive memory’ power is maintained. Thus the quiescent power
drain on the battery is greatly reduced.
To maintain the battery charge level, press the battery disconnect switch and
use the battery conditioner to charge the battery whenever the vehicle is to
be out of use for some days.
If the battery disconnect function is used in conjunction with the battery
conditioner, the vehicle may be stored for many months without additional
battery maintenance.
Caution: The vehicle security systems will be totally disabled when the battery
disconnect switch is used. The vehicle will be secured only by the mechanical door
locks. Ensure that the vehicle is stored in a secure location.
Caution: Close and lock the doors before disconnecting the battery. The door window
seals will be damaged if the door is closed or opened when the battery is disconnected.
