Battery : Normal or Calcium?

[Dave K]

I need a new battery for my E320 CDi (W210). It's been turning over much slower than normal in the cold weather. I rang around for prices and was aksed if it had a normal battery or a calcium battery. I've been and had a look at it and the battery looks normal to me. Am I correct to assume they can be interchanged and it would be OK to fit a calcium battery in place of a normal battery?

Many thanks.

Yes Dave, they are the same in appearance.

The calcium ones are higher capacity 'like for like' and recommended for eg diesel or lots of start stop motoring.

I got a 4yr guarantee calcium from Halfords a few weeks ago and am very very please.

Choice? Calcium is best.

BTW - check out Costco battrey prices if you know of them - bosch silver star I believe . . .
