which battery maintrainer to buy for my 2008 v8 vantage?
 

my battery died last night and it was a pain and hell to get it all up to working order!

about to order this. Should i get something else? also im assuming i would plug this into the trunk cig lighter (hopefully i have one in there)

ctek makes the AM units..which are pretty basic. They make others that are slightly larger but amazing.

I use BatteryMinder Model 2012. I have 3 of them. Reasonably priced. I've never experienced a problem with them.

I use a Battery tender by Deltran on all my cars. You can use the power outlet in the trunk(boot). They perform just as good or better that the factory charger and cost a lot less. Should be able to find several on eBay.

How old is your battery?

I bought mine off Ebay over 11 years ago and it is the Aston Martin branded one. Works great.
