My battery is on the out and need a replacement. It currently has an Interstate MTP-93 Mega-tron plus. What is the recommended battery these days.
I do have an autozone and napa parts close to my house. Autozone popped up a Duralast Gold Battery part # H8-DLG. It is interesting the description says for 3.3L turbo even though I put in 87 911 Carrera
The car sits a lot of the time and is typically on a trickle-charger in the winter.

 

The screw holding the bracket for the battery looks round? Not even sure if I have an ext socket if it will loosen the screw. Not sure if round because of years of putting in/out batteries. Also, the top of the screw looks like it would fit an allen socket? Not much room. Any suggestions on the best tools to get out.

 

 

New what ? Screw or battery ?
Which type did you get
I think you need type 48

 

Allan #6 screw, and an 8 inch wobbly extension.. I reused the existing screw and cleaned up some of the acid off the plate to hold the battery in place. When I put the screw back in I put tape to the head and the allan so it would not fall out (after it fell out once). Also, I got the Duralast Gold Battery part # H8-DLG battery. It had a 5 year warranty and the Platinum one only had a 3 year and it was $50 less.

It was a bitch to get to battery in and out.

 

Lol it is. I thought ours used a H6 but i could be wrong
Btw guess what that long Allen key with the rubber on the end in your tool kit is for 😋
