Silver/Calcium Battery

Aug 10, 2007 3 Replies

Just had a battery warning light come on spasmodically on my 52 Reg Mondeo 1.8 LX. Went to my usual garage and he checked Alternator and was charging ok so we surmised it was battery problem. Original battery still fitted since 2002. Red dot showing in battery window so that decided the issue.



Did not have a battery in stock so I went to local Tyre/Battery/ Exhaust place who did have one. I specifically asked him for one for my Mondy.



Fitted normal battery. I now find that, according to the handbook, I should have had a Silver/Calcium one fitted.



Do I have a problem.



Possibly...

The maximum charging voltage for silver/calcium batteries is slightly higher than for older ones. This might result in overcharging.

You may well have. The Ford Smart Charging System (SCS) expects to 'see' a CaAg battery. A normal battery will probably be damaged, and may overheat!

Maybe your model/year isn't so fussy, but I'd make sure before the battery fails and the warranty isn't honoured because it's the wrong battery.

If your car specifies Silver/Calcium and they didn't fit one then I think you should get them to change it.
