Vehicle Battery Charge

Various systems, for example, 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
(Refer to 'Battery Conditioner', page 11.29).
In cold climates this time may be reduced.
Aston Martin recommend that if this vehicle is to be left unused
for ten (10) days or more a battery conditioner (mains power
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 30 mile (48 km) 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 running
Excessive battery drain would ultimately mean that the battery would
not be able to start the engine.
