My Ride: 2003 325i
Just replaced my battery.
Tools in trunk were enough.

2003 325i

Car didn't start, only click. Gave it a jump with cables and it turned right on, leading me to believe it was the battery.

Autozone had the 94RN for $140..

Walmart had the MAXX 94RN for $77, 3 years free replacement. The MAXX 94RN fits perfect.
Exact same dimensions as the BMW battery (61-21-8-381-749), including the folding handles on the top and the vent hole in the same location, so no need to remove the white block, use any vent hose adapter, or put anything under the hold-down plate. It is 765 CCA with 3 yr/8 yr warranty. Is what another forum had also and it's correct.


Took 10 min to take out and put in. Took 1 hr driving to get different prices.

THIS FORUM ROCKS!

^ thanks for posting. I had to get a random battery from Napa when mine died, as it gave me no warning. I had to raid a nearby dumpster for cardboard to stuff it in the hole to keep it from moving around.

I'd like to find a battery that fits. I read the OEM replacement is garbage.

do you have to some type of reprogramming after replacing the battery? IDK why i am thinking this, I must have read something somewhere but can't seem to remember where...

edit: i am probably confusing a post about about car battery vs. the key fob battery or something...

so the 49DL is sedans and coupes, right?

no reprogramming needed. you may have to reset your clock and radio stations however. and you'll also lose your current trip odometer reading, the OBC mpg, and average mph readings i think.

i can only speak for sedan, but the 49DL works for me.

to keep all the memories I used the jumpe cables and I hook up the battery from another car in the power terminal by the engine compartment ( located in the left side when you face the engine ), Duralast 49dl worked well for my 330ci, the only thing was that I had to build up the top side by placing a plastic spacer to bolt the battery down.

Old thread but here's an update for Canadians...

Walmart has the PERFECT repacement. Energizer 108-94R.

Fits in perfectly , stock battery clamp secures the battery , and the vent holes are in the exact same spots. You have to pry the fitting off the OEM battery and it press fits into the new battery no problem. On the opposite side of the OEM battery there is a little plastic plug that seals the hole on the new battery.

$117.00 vs $262.00 at the dealer and comes with 3 yr full replacement warranty.

^ does this battery also fit for a facelift coupe which I have?
I rarely drive my car and I've had it run down to dead a few times before buying a trickle charger. My OEM is 6 years old and after a full charge dies after a week when not being plugged in.
Time for a change?

Just picked up this battery and installed it, I saw it a year ago but my battery was still good so i waited, I was going to post it guess you've already done that lol..

I cant see the coupe battery being any different than the sedan, if your battery is already dead just get a ride there with the dead battery, you'll need to exchange it anyway and check for yourself, too easy not to do...

My Ride: 2001 325i
Does anyone know if the Everlast 94RN at Wallyworld is a match for a 2001 325i? I need to replace my battery, and am hoping the pricing is still decent on these. I checked Autozone for the Duralast 49DL, as many have suggested but they jacked the price up to $112 (plus sales tax). Anyone priced the Everlast 94RL recently?

I just replaced the battery in my 2002 325i. The Duralast 49 DL was a perfect fit and it cost $93.99 plus tax. Used the tools in the trunk lid.

My Ride: 2003 330xi
I replaced the battery in my 2003 BMW 330xi with the Walmart EverStart MAXX-94R. It was a perfect match for the size of the OEM battery.

Here is a photo of the replacement battery:

Here is a photo of the OEM BMW battery (61-21-8-381-749):

I just replaced the battery in my 2005 330ci Coupe with an Advance Auto Part Autocraft Gold 94RH7 battery and it was a perfect fit. I got the battery fro $155 - $50 (coupon code)... so $105. The battery looks to be the exact same size as the OEM battery.

I am also in Canada (Toronto), yep, replaced my battery yesterday with the one specified above @Walmart - Energizer 108-94R, they had a few in stock, $117.00 Canadian. There was a $10 core replacement charge, refunded with return. Fits perfectly and comes with 3 yr replacement and a card for emergency roadside boosts if required. Note the plug for the 2nd vent hole is actually a small pull-out piece of plastic on the red plastic cover that comes with the battery.

Thanks

Thanks to this forum and this thread I was just able to replace my car battery on my own. If you knew me well you'd understand just how big a deal this is, as I'm not mechanically inclined at all. Much thanks to you all!

Went down to Autozone this morning and bought a 49-DL for $99.99. It fit perfectly! Its slightly shorter than the original, but its still pretty snug and doesn't slide or tilt around back there. Make sure you connect the vent tube as I mentioned in the previous post. You wont notice it on the stock battery since it is completely sealed. I was worried about losing the radio code but the only affects I noticed were the trip odometer was reset and the time showed --:--. NBD.

My wife left the lights on all day on one of our colder days of the season, so this thread proved useful!
The current/dead BMW battery was listed at 80 amp hours / 640 CCA. 12.25" long, 6.75" wide, 7.5" tall.
Advance Auto (no AutoZone near us) had the Autocraft Gold 49H8 (94RH7 not in stock) for $130.99, but you can frequently find a coupon online for 20% off. 760 CCA.
Walmart had the EverStart MAXX-49 for $82.00. 850 CCA, distributed by Johnson Controls. It's ~1" longer than the BMW battery, but there was plenty of room for it and no modifications are needed to use the factory-supplied hold-down or positive cable cover. The vent is on the outboard top center of the battery, but the supplied rubber fitting attached easily and accepted the light gray vent hose in the car.

I ended up paying way too much and bought the dealer replacement battery which didn't fit as well as the original....

The new battery didn't have a vent pipe like the old battery...
I don't see any openings where I can top up, is that still required in the newer batteries???

3. Make sure to top off the battery w/ distilled h2o every year.

Look closely - you might see a small round plug to pull out for adding the vent fitting.
Most batteries are now "maintenance-free" but it's still a good idea to annually check the fluid level and make sure the plates are covered with distilled water when low. You will have to pry the covers off.

Just wanted to say thanks to all the posters in this thread, but especially to koolkat, as I had an Advance Auto Parts a mile from my house (I'm in Vienna off 123), and used a $50 off $150 code (Code = VISA) to get this battery for the same price. Advance tested my battery (It was at like 145 CCA), and installed it for free (the guy installing it didn't hook up the vent hose. I pointed this out, while watching over his shoulder, and he hooked it up). Price at the local mechanic was $230, I'm sure would have been at least $300 at the dealer.

The 94RH7 fit without any modification, which was worth it to me in terms of time (I was in and out in 30 minutes). Only downside was my little time-setter stalk thingie broke when resetting the time afterwards...

ETA: One more thing I forgot to mention, I just realized there are two vent holes on the battery: one for the vent hose, and one has a plug. I forgot to grab the plug out of the old core, so that hole was just open, which probably defeats the purpose of venting. I just put a piece of foil-backed tape over it for now, but will run back by Advance in a bit to try to grab the plug from my old core...
