what is the oem or better battery to get for the e46 m3??? i see the csl had the bosch 096 s4... there are s3, s4 and s5's, whatever the difference is?
I've just bought a Bosch S4 for my weekend car. ECP have an eBay selling account which was cheaper than the regular website. £40 rather than £63 for a 063 battery.
CSL has a 55Ah battery from a Mini. I keep mine on a trickle-charger a lot of the time, and have reconditioned it every now and then, so get away with it
My suggestion is to go to your local BMW dealer and buy a new battery. Good quality at a reasonable price. Provided you don't neglect your car it should do 8 years or more without difficulty.
Don't be fooled by cheaper rubbish with a "3-year warranty".
cheers all, the 15 code works, couldnt see ph offer, and discounted c£100, of which i can find it for c£80. it looks like i have the s5 battery, which the ctek has managed to revive!
