Which car battery charger do I need?
If you know what sort of charging you want to do, there are just a couple of things to think about when picking a battery charger:
Engine size: How big is your engine? A bigger engine needs a bigger battery, which in turn needs a more powerful charger! Check that your charger is suitable for the size of your engine.
Battery type: What kind of battery have you got? Lead acid batteries work with all kinds of battery chargers as long as they're suitable, but if you have a gel or calcium battery, or an AGM/EFB battery that’s normally found in cars with start-stop functions, then you’re going to need a smart charger.
Features: What kind of features are you looking for? Do you want a digital display that’s easy to read? Perhaps a winter mode? Specific charging cycles? Have a think about your requirements and that will help to narrow down your options.
