What size battery is on an E46 M3?

[Andrew Coates]

I am looking to buy a battery conditioner to keep my battery charged up while the car is laid up for the Winter.

I have looked at several and the one that looks the best option is the CTEK MULTI XS 3600.

It says that it can charge a 75ah battery and maintain a 120ah one.

Would this model be suitable for the M3 battery or will I need the next one up (CTEK MULTI XS 7000)which goes to 125ah charge and 225ah conditioner?

Any help would be appreciated.

Thanks
