If you’ve ever
suffered the let-down of a flat car battery, you'll know what a drain it is. If
it does go flat for no obvious reason it may be time to replace your battery.

1.
A flat battery is one
of the top reasons for calling out the RAC. Causes are varied but fall into two
broad categories – either something electrical (such as the lights) were left
on, or the battery has become unserviceable and needs replacing.
2.
Modern vehicles are
equipped with a number of on-board computers that control and monitor various
systems. These often place a constant small drain on batteries even when the
vehicle is parked up. It can mean that when the vehicle is left standing for a
long period, when left in an airport car park for example, the battery can
slowly discharge.
3.
The battery is a vital
component of all cars. A good battery can last for over five years with proper
care. However, battery failure can occur in as little as three years, depending
on the usage, maintenance and seasonal temperatures.
4.
Premature battery
failures can be caused by defective charging systems that cause the battery to
be over, or under-charged; or other electrical faults.
5.
Ensure you get the
correct battery for your vehicle’s specification. Depending on the level of
equipment fitted, the battery specification can vary. It may help to make a
note of the numbers on the existing battery. However, be aware that if it’s not
the original battery, it might not even be the correct battery type for the car
– so check the owners’ manual or call an expert if in any doubt.
6.
Your vehicle’s
on-board computers may require particular procedures to be carried out when the
battery has been replaced. Check your owners’ manual or consult an expert if you're
not sure.
7.
More and more vehicles
now come with “Stop-Start” technology. This significantly helps drive down fuel
consumption, saving you money on fuel and lowering the impact of driving on the
environment. “Stop-Start” technology places greater demands on car batteries,
so you should expect to pay a little more for these more sophisticated
batteries.
8.
Don't forget battery
disposal. This must be done in an environmentally responsible way. If you get
the RAC to replace your battery, you won't have to worry about this – it will
be done for you.
Call in the experts if
you're in any doubt. All RAC patrols are experienced and fully trained, and
have the necessary equipment and know-how to diagnose your vehicle. If needed,
