Anyone know the OEM battery spec or can point me in the right direction, looking at lightweight alternatives and want to know which to get!
Also, anyone know the weight of the standard one?

OEM mini battery is 55Ah 480cca
185h x 175w x 240l
7.28" x 6.89" x 9.45"
B61.21.8.377.139

I actually just changed mine yesterday, went for OEM and have the old one lying in the garage. If I remember, I'll weigh it later on this afternoon for ya. It's a heavy yoke, but when I looked at my mates 80Ah one in his M3, she's tiny compared to that bad boy.

Just got myself a OEM, too.
Looking forward to get a lightweight from BMW, like Porsche developed.
Just a little expensive!! 2'k

Re, the Porsche one, you can already buy them:

I had in my list this battery -> http://braillebattery.com/
This for example is 6 kilos lighter and 31AH... http://www.braillebattery.com/index.php/batteries/b3121c/

Good work. Braile one that might be the ticket is 7.7KG or 1.8KG lighter than similar red top for not much more, thanks.

found this old m3forum post nathan
First off Exide makes the batteries for BMW (they are the OEM supplier). Schucks/O Reilly/Checker/Kragen/Murray's Auto (all the same company just a different name depending on where you live) sells the OEM exide battery.
http://shop.oreillyauto.com/ProductD...e=5005&PTSet=A (http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=EXI&MfrPartNumber=94R96P&PartType=5005&PTSet=A)
Take off the Autolite sticker and add the BMW sticker and presto you have an OEM BMW battery at $155 vs your dealer price.
There are also cheaper options. The Autozone 49-dl fits and is equivalent to the OEM at $90. Their computer says it does not fit but many have put one in without fitment issues.
http://www.autozone.com/R,53334/init...ductDetail.htm (http://www.autozone.com/R,53334/initialAction,partProductDetail/store,3375/partType,00175/shopping/partProductDetail.htm)
If you want to go light weight then there is the Mini battery which is the same battery that comes in the CSL. The 47-dl is the mini battery at Autozone for $90. It is only 29.5 lbs so you are going to save 19 lbs over OEM M3 (about 48.5 lbs) going with this option. The OEM Mini/CSL batt is 34.5 lbs and costs twice as much. If you have a large amount of aftermarket electrical gizmos on your car or like to listen to your stereo or run your headlights when the car is turned off then I would stay away. If your car is stock as far as electronics then you can run this without any problems. They are rated for slightly less cranking amps and reserve.
http://www.autozone.com/R,23190/init...ductDetail.htm (http://www.autozone.com/R,23190/initialAction,partProductDetail/store,3375/partType,00175/shopping/partProductDetail.htm)
There is also the Optima red top #35. It fits with the use of a custom spacer under the hold down bracket. A hockey puck is the most common spacer used. They weigh in at 32 lbs but have the same CCA ratings as the full size battery. The only drawbacks are they are expensive at about $190 and if they run low on juice they quickly become pieces of junk. So if you run your battery down on occasion you need to look elsewhere.
The Optima Yellow top is more reliable and is 36.4 lbs but costs about $220.
Then there is the Odyssey, Hawker, and Braille batteries. These are super lightweight dry cell batteries and are expensive. They will work in a car that has no electronic options on it. They are mostly for track use. If you are a super weight shaving modder then they are the way to go and you can get a 15lb battery to work. As a daily driver I would not recommend them though.

would these batteries work for a road car Nathan?
i am presuming stock CSL battery is about 15.7kg so 8kg heavier than the B2317 Braille. Thats not bad value $170 bearing in mind it costs £1200 to save 13Kg with the exhaust and £1000 to save 8kg with rims

No idea matey - my car has still got a 330 battery in it after I got fed up with the OEM CSL one going flat so personally wouldn't use one on a road car, could always swap it before track days though ;)
From 330 battery to the 2317 has got to be at least 10kg saved for me?
UK price is £144+vat
http://www.braillebattery.co.uk/index.php/batteries/b2317/
To work out what is required I'm simply looking at what varley recommend for the red top and the 30 is for up to 3.5L engines and the above is just below the varley in terms of AH and similar cranking voltage, just trying to work out if it will be ok with the extra load needed for night racing?

They are similar batteries but with less AHs.
This would mean that you cannot leave the car running with radio and lights etc for longer.
I personally don't do this...
Also since the last visit to the dealer that they destroyed my battery (they left the ignition on during the night...).
I will go for this one -> http://www.braillebattery.co.uk/index.php/batteries/b3121c/ (the non-carbon one b3121 is the same thing and a bit cheaper).
31AH is a compromise compared to the 55AH of the original battery but it's not so extreme like the 21AH.

When you say "car running with radio and lights etc" do you mean idling or with the engine off?
I've got underdrive pulleys on all ancillaries including the alternator so it provides less current at idle than standard anyway, want to make sure I'm not going to go to far and end up with a car that refuses to start after refuelling!

When the engine is working, the alternator is providing electrical power (in combination with the battery).

How much does that weigh?
Porsche plans to market a new lithium-ion starter battery for three different 2010 model year cars. The battery weighs under six kilograms, roughly ten kilos lighter than a normal lead battery.
Users of the 18Ah battery should notice no difference in performance when compared to the 60Ah Lead battery. The reason for this is that lead battery users normally get the benefit of just 30% of the battery at any given time, versus the 100% available power of the Li-ion version.
Purchasers of the 911 GT3, 911 GT 3 RS, and the Boxster Spyder will be able to get the lightweight battery as an option. German pricing for the battery is an astonishingly high €1,904, including VAT.
As if that is not bad enough, previous purchasers of those three models can retrofit the battery for €2,499, beginning in February. :banghead::banghead:

Ordered the 2317 in the end, nearly went for the 2015 but bottled it and decided that for the sake of 0.9kg I'd rather have the higher capacity one.

New regs mean we can run about 90kg lighter with the same power so a bit of weight saving is good but can always turn the engine back up :)

Just wondering if anyone's tried the braile L//w battery on here. If so, how did you find it and which model to go for.
Have looked at these for a while, but slightly worried about causing electrical damage due to low wattage.

I ran the Braille 8317R 7.7kg for all 2010 without issue. However my car does get conditioned every few days and it isn't subject to daily winter short runs

As stated I bought the 8317 too, mind you I've only driven the car twice since (Silverstone and Snet) and the battery is isolated whilst the car is standing. Car does get started and moved around a fair bit though.

tbh as funny as you guys are, its a pretty cheap way of saving over 8kg, for only £130 (when i bought mine)
So thats £16 per kg.
if only the rest of the weight loss was so cheap and easy!

I have one of these http://www.braillebattery.co.uk/index.php/batteries/b2015c/
I also bought the light-weight mounting kit which has been siliconed to the
battery bay floor (didn't want to drill holes in the car).
Aside from the battery saving weight, you can also remove that heavy galvanized strap!
Will take some pictures at the weekend if anyone interested. :thumbs:

You haven't come to your senses to clear out that boot have you Rich!?
I also run the Braille 8317 & made an aluminum battery clamp to house it and as Shim states it a v.cheap way of saving over the OEM CSL (bmw mini) @ 15.6kg. Think the saving over the Z4M battery is 12+Kg. It wont hold its charge as long as its fatter alternative so if the car isnt being driven make sure to trickle charge it.
