What is the correct battery size for my 3b s2 coupe?

[caddykid88]

I need to replace the battery on coupe as it is not holding charge. the existing one only just fits under the strut brace at a squeeze. there are no stickers on the battery casing to identify its ah type etc. can anyone tell me which one i need to get?

i bought a bosch s3 battery last week and that just fits in...was a 70ah unit

Is there a minimum to how small the battery can be? I only use mine in the summer anyway, and there's chances of getting rid of some lbs with a smaller battery.

Get the biggest & best that will still fit... IMO

seconded...with as much cold crank capacity as possible

The Bosch Silver batteries S4 or S5 are very good - Halfords stock them or you can find them slightly cheaper on the web
