Batteries eventually go bad and need to be replaced. It’s easy to know when a battery in an Aston goes bad because a weak battery will cause a bunch of electrical gremlins. In most cars, replacing the battery is a quick job. Not so much in an Aston.

This DIY guide shows you how to replace the battery in a V8 Vantage. If you want to get a lightweight battery, I offer a kit that drops nearly 30 lbs of weight!


Somewhat easier than changing the battery in a V8 Vantage, the DB9’s battery still takes some know-how to replace. It’s easy to know when a battery in an Aston goes bad because a weak battery will cause a bunch of electrical gremlins. In most cars, replacing the battery is a quick job. Not so much in an Aston.

All modern Aston Martins have a Tire Pressure Monitoring System. If you get a warning light due to the sensor batteries being dead and don’t want to replace the sensors, you can eliminate the fault light using Redpants’ TPMS Fault Defeat (this does not fix the problem, it only prevents the warning light).


A thorn in the side of many a convertible Aston owner, the convertible roof module (CRM) causes all sorts of problems when it goes bad. It’s easy to replace, but you’ll need to have a dealership reflash the car with an AMDS in order for the new one to work.
