It tells them if there's a massive drain on the battery somewhere. Easy to do, remove earth clamp from battery, put multimeter leads between clamp and battery and set to 10 Amps (or 20 if your multimeter goes that high) and with everything in the car turned off and all doors/boot etc shut u see if there's a drain. 50ma max, ab more and u have a drain somewhere. Next step if u have a drain is to start pulling fuses one by one u till the amp draw on the multimeter drops and there u can see what circuit is causing the drain
