Replacing Battery in my 2002 A$ Quattro

**jcorytull** · 04-10-2008 08:11 AM

Replacing the battery in my 2002 A4 Quattro 3.0 seems a little more difficult than batteries I've replaced in the past. Anyone got some experience to share on that?

I finally found the bolt securing the battery in place, but it looks like its going to be a real pain just to get the battery out. I really don't want to take it to the dealership to have them change the battery, but I also don't want to get in over my head.

Help please!!!

Slide a ball head hex key down there and slowly back that bolt out. Then just pull the battery straight out. Not difficult.

thanks skeeball.

what about that vent hose coming out of the side of the battery? do i just pull that out?

yes. you can pull it right off. its just a breather hose.

i got a duralast, fits pefect and way lighter than the oem battery. 5 year warranty. it will come with a rubber hose that connects to the breather hose.

I read good things here on optima red tops but can't speak from personal experience.

optima is defin. the best one you can get. the duralast was only $60.

optima batteries are great if you need a ton of cranking amps and deep cycle ability.... I think you'd only need something that expensive and capable if you were doing big stereo, or using a DC->AC inverter.

I went through three yellow tops in my last car over five years with a 3+kW competition grade stereo. Any lesser battery would have been replaced on a monthly basis. The batteries were replaced under waranty(and some trickery!). Unless you're pushing a few thousand watts, you have no need for an expensive and extremely heavy optima unless the waranty, sealed gel-cell tech and reliability outweighs a 50lb, $180 dollar optima.

I recently bought an autozone replacement for the OEM battery. It starts the car!

Hey Scary Gary, thanks for the tip. Was the replacement you got at Autozone a Duralast?

My OEM battery exploded one day a few years back! my dad started the car and boom, crappy smell smoke and when the dealer pulled out the battery, it had blown out the side! costed us $250 for a new one installed at the dealer, having no warranty sux up the ass!
