Thread: Mixing battery types

Not to start an argument but Agm charge faster than Calcium, calcium charge faster than antimonial batteries which are rare these days. Agm have lower internal resistance . Only fitbthe type of battery recommended for your car. Agm charging sustems are set to a lower voltage ie ;14.4 max where as a Calcium will charge up to 15, depending on the car up to 15.5.
Putting an Agm into a car designed for a Calcium is a recipe for disaster.
How do I know? 30 years of selling batteries

Battery was changed to an AGM EXIDE SSAGM-88EU.

Cost more as you would expect but rightly or wrongly I feel happier.
