It uses both at the same time.
Nothing deceptive about it.
Batteries last longer than you think. There's a taxi driver using a Toyota Prius and drove more than 200k miles on it and still has the orginal batteries.....it hasn't failed on him.
It is not mileage, it is AGE that has affect on batteries. If you can get 500K miles within 5 years then yes it will happen, but if you only drove 50k miles in 5 years and you will end up need replace batteries.
No batteries last forever.
I just wish batteries last longer than 5 years....10 years would be more reasonable for the general market.
Yeah, I agreed but the batteries is something that I really don't like is that it has chemicals, not easy to dispose of. One thing I can say for sure that today batteries are more durable and powerful yet it does not live forever whether use it or not.
