Check the battery before you fit it to the car.

Make sure it has been off charge for at least 6 hours before you do this.

Fully charged you should see something like 12.6 volts or over.

You will see a dramatic change in two days of use if there is no charge going in to it.

When it's close to 12.2 volts you will have trouble starting the engine.
Thanks for that. A further question now if you don't mind. Presuming the althernator is at fault and the battery charging light illuminates. Roughly how many miles will I get before seeing the battery fail, and what will the battery voltage fall to?

Thanks again Jon
