Duralast 49-DL still preferred battery?
Did a search here and elsewhere and found that the Duralast 49-DL is the "drop in" replacement for the E46 unless you have a convertable in which case the battery compartment is smaller.
Is this still the case for my 2004 M3 (non-convertable)? In other words any downside to this battery that has been discovered? I've got a dead battery and need to get one. The dealer OEM is $202 and this is only $101.
Yes it's a great battery for the E46, price has gone up in the last few years though.
OK, I got one and installed it.
I have seen posts that this battery does not fit/ results in the cover being unable to fit.
The 49DL posts are years old, so maybe this is an update.
The 49DL will fit but-
1. you have to remove the old plastic post that clips the bottom of the OEM battery to the battery holder. It just flips out so no big deal. The OEM battery is smaller than the battery holder so this piece of plastic prevents lateral movement, it pops out and you need to pop it out because the 49DL is longer and will not sit with the plastic piece in place.
2. Next, you have to install the tube and extension clip to the 49DL to connect the evac tube to the existing evac tube. The fittings do fit but there is a right angle connection so make sure it is not crimped when you install the tension mount. The way to do it is to install the extention and tubing to the existing tubing in the car leaving it free. Make the connection to the battery last after the battery is put is in.
3. OK, so you have removed the plastic post and put in your tube extension, so put in the new battery, the 49DL. It just fits in the mount.
4. Connect the tubing to the evacuation nozzle. Its a right angle so be careful.
5. Put in the original brackets.
6. Here is where the problem occurs. The 49DL is lower than the original battery so the push down clamp will not hold it. If the push down clamp is pushed all the way in the battery still moves. You have to lay something on top of the battery (maybe 1/2" or so?) in order to clamp the battery down using the original clamp. I used 3 layers of speaker gasket tape and it was not enough. Finally laid a section of floor molding on top of that and it did the trick. Searching on the internet reveals that a hockey puck will work.
7. The battery posts are the same dimensions (I think) as the originals so you don't need to rework the clamps. At least I didn't. Just connect the + first and - second (at least that is what the directions say to do).
8. You need to remove the red + cover from the 49DL and install the BMW cover. Guess what? The cover pops out and there are 2 holes that will allow the original OEM BMW cover to pop right in. Not perfect but close enough.
9. The trunk battery cover will fit over all of this no problem but its hard to know if your tubing was pressed (and no longer works) because you cannot see what happened. Be careful and good luck.
So there you have it, a 49DL does indeed fit but involves a small amount of tweaking to get right.
I have seen posts on the internet that the + and - terminals are swapped- they are not. They are in the right spot. Posts that the plastic cover will not fit are also not correct. The only drawbacks are the right angle evacuation tube that is a tight fit and the low height which needs a shim.
Price was $89 + $12 ($12 refunded when you return old battery) as of June 2009 from AutoZone. The dealer quote was $202 for an OEM battery.
I realize this is a little late, but the AutoZone 94R-DLG is a direct drop in. Even has vent ports on the end of the battery rather than at the center, so the vent tube fits just like OEM. It costs more, tho - $140.
Just got the Bosch (for a Mini Cooper S) from Pep Boys. The CSL uses the Mini Cooper S battery. No need to modify and its lighter.
best deal in town however auto zone is discontinuing the battery.
I called most of the stores and no luck.
too bad they have a good product and they are not
going to carry it.
It's a shame, good battery. I wonder if there's another Duralast that'll fit back there that performs just as well.
Edit: Bosch Group 49 battery, can be found at Pep Boys. 850CCA, 1000 CA. Identical to Duralast, and sometimes on sale for $63 as well.
I don't see how it can be gotten cheaper, although I think I missed a Bosch battery rebate that expired recently for $20.00.
I have had a couple times where I was working on something, and had the dome light on or some wires disconnected for a few minutes,, and the car would not start.. other times it just fires up and no problems..
I will have the battery checked either today or tomorrow, on a load tester at a store.
I have a charger at home if I need it and carry jumper cables. But, I should not have to worry, plus I live in a warm part of the country and the weather here is not hard on batteries, so,, it's probably has a bad cell. And it was probably marginal. Also, this car is not hardly ever driven (maybe I don't give it enough driving time to charge it well enough, but I don't really think that could be the problem), because the old card we are going to junk, is still being used until we get the final date set to junk it. This gives me time to make sure it is all good to go.
Well, since it is a used car, and is really nice, it wasn't perfect, had to install a couple new tires. Put new rear brakes on. I can't expect it to be perfect, although I wish I could have gotten perfect used car.
If the battery test shows any battery problems I will probably go with Bosch. The Walmart battery has good reviews but after 3 years, they seem to drop off... I believe it should go at least minimum of 5 years without even looking at it, we maybe look to just look for any corrosion... Sears search says they don't have any battery for my car (We have had lots of problems with Sears orders over the last couple of years, not sure what the heck happened with that store). Autozone, not as good a deal as Bosch even with a coupon search.
I am not pushing any one store, but they all treat me well. With 3 cars in our family, and all old, I had my share of buying and installing parts. They all have no hassle warranties.
I do want to ask about the 2001 BMW 430i charging system:
Doesn't the BMW computer tell me if the charging system has any problems? I mean idiot lights. I never get messages after starting telling me anything is bad.
btw, the Bosch Premium Performance Battery (*that I might buy), and was under the impression a group 48 belongs in it. But, it that is what is recommended at the store. Not even going into who is the real maker and who slaps their brand label on. It does say 3 years emergency jump start assistance, but I can't find any website with info on that.
