Batteries... Group 48 seems to be disappearing

[lcoleman]

Group 48, 49, and 94R should be interchangeable. Since there is always some variance between brands, it's best to test-fit or make sure they accept returns.

I just bought a battery 3 weeks ago from Advance Auto. Did some research in Consumer Reports, and AutoCraft batteries are pretty good. I haven't had any issues with it so far... It is part number 48H6, costs $132. I ordered it online (for the 15% discount), and a store nearby had one in stock.

48H6 - AutoCraft Gold Battery, Group Size 48, 730 CCA (3yr Repl Warr)

It was a pain in the ass to find, because most of the auto part chain store's websites can't find a battery for an E30. The dumbest thing is that you can't just search there for the friggin size you want! I considered upgrading to a size 49, but I'm not too smart on auto electrics and I didn't have the time to research & learn. I just stuck with stock size.

I have one of the everstart maxx from Walmart, it's been pretty OK. I had to warranty it in the winter because it didn't work so well below freezing but the replacement process was painless and the new battery has been fine. It was about $120 with core charge and everything.

My local Wal-mart stocks them. 100 dorra, 3 year warranty

Costco no longer stocks an e30 battery. I brought a Kirkland with an 84 mo warranty back for replacement and wound up going elsewhere. What they offered me for a warranty refund was about the same as the core charge on the new one so I passed or I would have been sitting there without a battery and no net $$ :)

Some Costcos in Orange County still have them. YMMV.

Get a wal-mart everstart maxx battery they sell both Group 48 and 49 (I recommend 49). All batteries are basically made by three makers exide, johnson controls and east penn. The everstart battery is made by johnson controls which is a quality battery, east penn also makes a great battery, I would stay away from exide.

Look here on how to vent properly:

I changed mine at Pepboys (Bosch) Group 48...after all the rebate costs me $82 plus tax...

I highly reccomend the MTP91 Interstate I put into my E30.

Costco Kirkland brand by Johnson controls....3 year full replacement 100 mo prorate. No testing...no questions asked return policy. U just have to remove and install it yourself.

the napa branded batteries are rated highly (or were) by consumer reports

[browntown]

depending on the brand, group 48 interchanges with 91 and group 49 interchanges with 93.

Group 49/93 is the longer one that fits nicely in the factory trunk tray.

we like interstate batteries, had good results with them.

x2. I've sworn by Interstate for a very long time. I use them exclusively in my own cars, and any shop I've worked at, I've swapped the stocking brand to Interstate. I put 15 years of experience/use on the brand.

price of batteries have gone nutz IMO

Yeah they were trying to exchange for a group 47. Said nope. Will look at a 49.
