Batteries in cars die. Even well cared for ones. The Bosch AGM battery I installed six years ago in my 2005 Aston Martin DB9 Coupe was failing and leading to weak starts. As this is a condition many owners can suffer from (leaving their cars stored) I thought a video on how to diagnose if the battery was actually bad, or just in need of a proper charge. Following the official Aston Martin Battery Care guide I show you how you can easily test it on your own, and if it does need replaced I offer up a new alternative battery to consider.
