Battery OPTIMA or Duracell

Optima batteries are some of the best batteries you can buy. THey are gel cell batteries, not like a conventional dry cell like in your car now. They are also deep cycle batteries, sealed so they never leak, and have 2 sets of battery terminals. They are practically indestructible.

That's all I'll run in my aircooled cars. They're not exactly light, but you can mount them sideways and they'll never leak. Those 2 features alone are worth the price of admission. Rust sucks and so does battery acid.

spend the $100 on an optima its well worth it

Optima Yellow Top. You can play the stero (amp/sub) all day and the car still starts. I've done it

Optima Orange Top.

I would say if you have problems with lights dimming and stuff when you are using ur electrical accessories, then get an Optima battery, also if you have a sound system in your car I'd recommend an Optima

optima red top fits fine in my 87gti, cut some plastic stuff to fit underneath so it would hold a little tighter, there were a few mm of space between the lip on the battery and the metal lip that is supposed to secure it.

NC-GTI, I haven't been in a VW since my '82 Rabbit back in the mid 80's but a good friend who's owned a Corrado, Rabbit, Fox, Jetta and now a GTI has had too many battery failures and his recommendation of the Optima battery is just some good info I'm passing along.

FYI... My first red top didn't last very long because I don't drive my car much. The car would sit so long that it would drain the battery, and so I was constinantly recharging it which is apparently not good for the battery.
