Can you run a fridge off a 12v battery?

Fridges should never run off the cranking battery that you use to start your vehicle. The only exception to this is while you are driving if you absolutely must. The reason behind this is simple – your cranking battery is imperative to start your vehicle, and if you run it flat you can be in serious trouble.
