Battery?

[karbonkid]

I have admitted the battery has given up. After constant recharging its not holding its charge any longer. Without a doubt its down to my short journeys, but is possibly due one.
It never holds and I always make a thing of manually turning off the interior lights when the doors are open for a short period of time when cleaning, wheel change or general.

I've heard that these were taken from the Mini, are there any better batteries over the OEM CSL ones, ie Performance, Life & lighter?

[shimmy]

yes better but heavier :bigcry:

just buy the replacement and CTEK batery conditioner :thumbs:

li-ion ones are miles lighter - around £1.5-£2k though!

Here here,:whistle:

I know that you can buy a CTEK conditioner over the counter at BMW, its exactly the same apart from a lovely BMW sticker on it. Turn the charger over and it has CTEK stamped on it, I believe BMW charge £50 ish pounds. :thumbs:

Mine is just sitting in the garage on trickle at the moment, saved me spending £100 for exactly the same problem.

If you need the part number let me know.

or Costco do a CTEK

Cheers all. I may just get an new bat when the car has come out of winter storage, but at the moment Im still driving it till I can find a winter runner. Does the car need to be constantly fed with power or can it be disconnected as Im not fussed about the current battery killing over?

My battery has started to hold less and less charge due to the car loafing in the garage a lot recently... :banghead:

Getting mighty fed up of disconnecting the battery to charge it every other weekend so have just ordered a CTEK Multi XS3600 to help resurrect it!

Linky: XS3600

make sure you fit the plug in adaptor to the battery straight away as it means you can refit the lining/tray above the battery and just plug it in - makes life alot easier

The OEM supplier for BMW batteries is Exide - but buying an Exide battery is exactly the same as buying a BMW battery, they are just rebranded and marked up.

A good alternative is the Mini cooper battery - which is exactly the same as the M3 CSL battery - you save about 19lb in weight from the OEM M3 Battery and it'll crank okay provided you don't run heavy audio equipment.

Just check that the CCA has enough juice to get your car going.

The standard E46 M3 battery Exide Classic CCA730 94R-60



It's actually used on a lot of other European cars (might pay to see which dealership has the cheapest price):

for e.g. Audi A4s, Chrysler 300, Dodge Challenger, Jag X-Type, Jeep Grand Cherokee, Commander, Land Rover LR2 and 3, Merc C300 and C350, Porsche Boxter, VW Gold, Jetta, Passat, Touareg

The Mini Cooper S Battery is Exide Classic CCA 600 - Part 47-60


Used in even more cars .. like Audi TTs, Jags, loads of Mercs, Loads of Saabs, Loads ov VWs and virtually the whole Volvo range LOL ....

But if you are really really weathy and have nothing else better to buy ... get this: I can't remember who makes this now, but I am sure I can find out with a bit of digging.

[shimmy]

ive gone for this!

7.7kgs

I've got the same one as Shimmy and can confirm after yesterday that it will crank the car over loads of times without going flat.

Tom - are you thinking of Voltfreaks for the li-ion battery?

No, not Voltphreaks ... although they do have some pretty cool and reasonably priced products I must say !!

I believe the Porsche Lithium-ion is made by Li-Tec of Germany

I went with the heavier one as the car is used for endurance racing and I'd rather carry a few extra kgs than it not start after refuelling!
