Battery Bosch or Energizer

my only option for a "proper" battery was a red top at $150.00. The next best thing was a group 47 Energizer, 590 CCA, 3 year full replacement, 7 year warranty from Sams Club for $65.00. I just dropped a load on the clutch and I don't plan on keeping the car for more than another 3 years. I only use synthetic oil so it cranks easier in the winter anyway. SO I got the energizer.

When I worked at AutoZone we carried the OEM Bosch battery, and it was about the price of the Duralast Gold.

I bought a Bosch 48-700B from Pep Boys. The guy that helped me knew a lot about batteries and looked up the right one in the computer without any problem.

Bosch battery from Pep Boys here in Raleigh, NC was $89. A couple lights were on the dash after I replaced it, and I called the dealer. They said after driving about 50 miles or so, all the electronics reset themselves. With tax, it cost me $96 and about 15 minutes to change the battery.... The Bosch battery I bought was actually a couple lbs lighter than the factory A4 battery as well...

You can also pick up a Bosch battery that fits for around $120 at Pep Boys. I changed out the battery on my 02 about 6 months ago and other than waiting a day for the power windows to reset there was nothing else that needed resetting.
