I replaced batteries in two cars last year, both of which were 10 years old. One was a Motorcraft battery, the other was a Duralast battery from Autozone.

I replaced one of them with a Walmart battery and the other with a Duralast.

I keep all of my vehicles on battery tenders at all times. I believe that is the real secret to getting batteries to last 10 years or longer these days.

I've installed quick disconnects on the battery posts that have male and female bullet connectors. Makes it a little easier and quicker when I want to drive the vehicles which is frequently

On Ol Roy I connect the battery tender to the positive lug of the starter and the ground strap. This way I don't have to go under the floorboard to deal with it
