Hi all

I plan on replacing both batteries on my BMW as I have no idea how old they are and they struggle to start the car if it's been parked for a few weeks. It has two identical batteries, one on either side of the boot (apparently it's done like this for weight distribution... personally I'm not convinced). I replaced my Omega battery about a year ago on TC and was surprised how cheap it was, around £40 for a monstrous thing which is actually too big for my car, I had to remove a piece of plastic trim and do some shuffling to get it fitted, that's what the VX dealer said was the right one for the MV6! The BMW ones are definitely smaller than that, they're still reasonably large though so I'm guessing the next size down.

Does anyone know the specs of the batteries available on TC, in terms of Ah, CCA and physical size if possible, and also the corresponding prices?

Incidentally I need a new battery for my SV650 before selling it, and it's probably going to cost me more than the Omega one did, despite being about a tenth of the size!

Cheers.

3.0v6 vx battery 72amp part 93176583 rrp £53, TC is £37 9 all prices exclusive of vat)

the one for the 3.2 is 85amp  and i think about a fiver dearer..

Cheers mate, maybe I have an 85 amp in mine then (although the guy definitely was told it's a 3.0). Are there any smaller sizes, and do you have any idea of the dimensions? I'll get the measurements and hopfully capacity of the batteries in the BMW tonight if I remember.

No dimensions im afraid sorry (got prices for all in tc book) other sizes arer 55/66/72 and 85 amps prices from £25 to £44.

These are listed under the omega section so there will be other sizes for other vauxhalls - probably smaller.

Vx do standard battery sizes to fit almost all cars......so sure you can get them.

So are batteries of a particular capacity normally the same physical size? I want to be sure it'll fit, as the Omega one was definitely too big but I managed to shoehorn it in with a little effort -- this is unlikely to be possible on the BMW due to the batteries having a dedicated compartment on each side of the boot. I'll have a look for an Ah rating when I get home.

No - there is a standard industry code for the battery size, e.g. 065 etc, but in my experience even a battery bought off the Bosch catalogue did not fit my wife's Previa, so it is still only an estimate...

The battery for my TDM 850 was 'only' £60! Apparently it's the same as a R1 and the bike was built around the bugger.

Thats no surprise given that Previas are Jap motors and japs have a realy obscure set of battery sizes....

They do - the original Toyota one was far too expensive, I eventually found a Korean one at a battery place down in Gillingham... and pays £80 for the pleasure of having a battery with only 2 years warranty as opposed to the industry standard of 3 years. It fit perfectly however…

Both the Bosch (from Costco) and Unipart (from a Brown Brothers outlet) batteries were the right ones according to the manufacturers catalogue, but in fact where around half an inch longer so did not fir in the ‘cradle’… they were half the price of the Korean one and would have worked fine if I left it slightly tilting and done away with the top strap holding it place, but this is not how I maintain my cars…

You would thing that Bosch or Unipart could bother to check the actual length on the battery? At any rate, I recommend that you take-off the old battery and bring it with you, then physically match it against the one you buy off the Vx Go catalogue…

[Paul M]

Taking off the old battery is a good idea, and although the car will still run with one battery (they are wired in parallel) I don't fancy the idea of it, especially since the disconnected positive terminal will be live! Under normal circumstances I could take the Omega but that's currently off the road due to a spark plug that decided to part company with the head (see my thread in General Help). So not sure how i'd get to the dealer with the battery, other than removing it in the car park which might be an option.

Just had a look and it's 74 Ah, 680 CCA each side. That's a lot of battery power, you'd think it's a hybrid

sounds like it - its between the ampere of the 3.0 one and the 3.2 one....

I've always gone for the juciest battery i can fit in the hole.

Must say the one and only time i had to replace my battery on the TDM i got it at a silly cheap price.....god i enjoyed (abused) that bike.lol
