C Max 1.8 Petrol - Calcium Batteries - Chris M

The battery on my CMax appears to have died - it's 8 years old, so not too bad. It's of the calcium variety, so from previous advice on here, I intend replacing like for like. The Bosch website lists the S4 (Silver) as the direct replacement, but it doesn't mention 'calcium'. None of their batteries do. Does anyone know whether they are indeed calcium?

On checking the Euro Car Parts website (I have a branch nearby and they are open tomorrow) they too list the S4 among others, but again, no mention of a calcium alternative.

Hmm, the product PDF for that has a timeline of Bosch battery development, leading up to the present, including under the 1980's: "Introduction of Lead / Calcium technology".

I reckon that's a "yes".

A visit to Euro Car Parts this morning and the chap said that nearly all batteries are now calcium. Very happy with the price of £54 for a Bosch Silver 4 year guarantee.
