No.Isn't it the case that the more 'gizmos' you have, the quicker your battery will deplete?
The alternator in a car powers the items in the car and charges the 12V battery. Cars with more electrical gubbins in them have more powerful alternators.
The 12V battery is only used when the car is started, or when it's sitting there with the engine off and someone has left various items on. That's why there is a red battery warning light which illuminates when the car is switched on but the engine is not running.
The only ways to deplete the 12V battery are to leave items in the car switched on when the engine is off, or multiple cycles of starting, driving for a couple of minutes, stop.
It's the same for ICE, hybrids and full electric - the only difference with electric vehicles is that the 12V battery is charged from the traction battery when the car is switched on because they don't have an alternator or an engine to drive an alternator.
Quite. There was something wrong with the Prius or the 12V battery in it.To recap, he had three consecutive Picassos from new and never once had a flat battery,
