Just charging my flat car battery. It is a Repco ultra high performance (lead calcium technology) sealed battery. I am using a multi stage charger. Should I use the lead acid or calcium selector on the charger or does it make no difference?

Hi there,
It is recommended you use the Calcium setting to get the best charge into your battery.
