03 E39 M5 Battery (where to buy?)
My 2003 E39 M5 needs a new battery. I'm trying to find
a place that is close to home (downtown TO) that will sell
a replacement or OEM, for a "reasonable" amount. I looked
on, but they don't even list a

Can someone please recommend a good place to find a
battery locally ? I know I can get one in Niagara Falls for $165

Thanks in advance

Iirc, all batteries are put in designation categories.
Go to a local NApa or something and get them to look up a battery, they will tell you what the disgnation is which fits. There is nothing special about an M5 battery, you just need one that has the + and - on the right side (if it even matters) and it fits in the tray and provide the output which is necessary for the V8.

From my experience, my Range rover, my e34 M5 and current M5 use pretty much the same battery.

I bought a battery for my e34 from Eurostyle (it was used but only 1.5 years old for cheap) and when I needed to get one for my RR I got one from Napa for like 140 bucks or something where the dealer wanted 3-400$.

Actually, the battery for a E39 M5 is quite different than anything I've
seen before. First, it huge and designed to fit in a tight space in the trunk.
The battery is vented and has two handles on it. What I found was that
there were only two or three replacement batteries that would even fit
in the battery compartment properly. Other batteries may work, but they
don't fit without adding risers and spacers to position and hold the battery
in place.

BMW Toronto wanted $405 + HST or $458 CAD for the battery, they
did not offer any refund for the old battery core and this did not include
any cost for installation.

I ended up purchasing a battery from Advance AutoParts in Niagara. They
had an exact replacement battery (Made in Germany) for $162 USD. I
ordered it online for pickup at the store. During checkout, they had a
promotion going on for $30 off purchases over $150, so in the end the
battery cost me $132+tax or $143.00 USD. And they gave me $5.00 back
for the old battery core and offered free installation if I wanted.

The battery fit perfectly, and has a 3 yr full replacement warranty and
is prorated after that.


Here is a shot of the battery sizes. I got this off the E39 list. My battery
is exactly the same, only has a 6/2011 date.

...or you could buy an Odyssey battery. Not cheap, but one of the best batteries out there!

Bah I need one too.. Does Costco (Kirkland) carry anything that fits? (95R, 93R, 49?)

last time I checked the dealer price was actually pretty good. Have you tried them ?

I installed an eliminator battery in my 540i and i am very pleased. I beleive its the same size as the m5 comparing it to the pics you posted.

Ended up with an Exide Performance Group 49 battery, 10-7249-4. 850CCA, 160 RC. Pretty sure it's a traditional wet-cell (not AGM) battery, but has vents on both sides, so no extension required, you just need to plug the one on the -'ve side. Because it's a Group 49, it's slightly smaller than the 95R and just needed some spacers (rags, cloth, bubbles, etc.) to fit. Felt significantly lighter than the OEM mammoth (64lb) but didn't measure.

Sorry to bring up an old thread,

I bought the same Exide battery as you listed, but i was wondering what you used to plug the negative terminal side vent?

And on a side note, I'm reading on some other posts that people say you should be venting from both sides using a 'T' joint. Not sure how much truth there is to that yet.

ClayMan 01-02-2013 05:05 PM

I used a self-tapping screw to plug one of the vents. Good luck!

My battery just took a dive this AM :(

Canadian Tire stocks one for it too, around the same price: $150.00.

I have one I was going to post for sale. OEM BMW M5 battery, needs to be charged tho

Crosstown battery on Musgrave, best prices....

Just as a tip, please make sure your vent is hooked up right.

I had my vent come loose before and my trunk ended up reeking of sulfur for weeks. In most cases it'll be fine, but for the odd situation, the proper vent will save you headaches.

Oh, and I got my battery from Advanced Auto in Buffalo, just a few mins from the boarder on Niagara Falls Blvd.

Not to mention getting blown up. The gas that "vents" is explosive
