Choosing the right battery for your MG
For MG, EFB or AGM on start-stop models; the electric range uses a conventional 12V battery that is easy to overlook because the car is otherwise electric. Most of the current range has a start-stop system, which means AGM or EFB is the floor, not an upgrade — a standard flooded battery in a start-stop car is cycled far beyond what it was built for and typically fails inside a year.
