To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.
