Vehicle Battery Charge

Various systems, such as the clock, security systems and Infotainment
centre system continue to drain battery power even with the ignition
OFF.
A new fully charged battery has the ability to start this vehicle, if left
unused, for up to 45 days without a battery conditioner being used.
In cold climates this time may be reduced.
Aston Martin recommend that if this vehicle is to be left unused
for 10 days or more a battery conditioner should be used if mains
power is available.
Battery charge can be drained excessively in a number of ways:
• If the vehicle is unused for long periods of time.
• If the vehicle is used regularly but only for short journeys, e.g. less
than 48 km (30 mile) a journey.
• If electrical systems are in use without the vehicle engine running.
• If the vehicle key is left in the ignition control for long periods of
time without the engine operating.
Excessive battery drain would ultimately mean that the battery would
not be able to start the engine.
Battery Conditioner
(Option)
Warning: Do not attempt to start the vehicle with a battery
conditioner connected to the mains supply.
Warning: Do not smoke near the vehicle battery. Prevent
flames and sparks. Explosive gasses are given off by batteries
during charging.
A battery conditioner is designed for conditioning of partially
or fully charged batteries. It will not effectively charge a
discharged battery.
For indoor use only. Disconnect mains supply before
connecting or disconnecting the battery charger to the vehicle.
The Aston Martin battery conditioner is suitable for use on all
types of 12 volt lead acid batteries.
