Knew a dude that was asked several grands for replacing his hybrid Yaris batteries. He couldn't afford it, so he drove everywhere with the old battery. Because of the extra weight, he ended up consuming more fuel than the purely ICE Yaris.

That shouldn’t work. In a Toyota hybrid it’s the electric motor that effectively starts driving, and is also responsible for starting the ICE. So the car doesn’t really work with the drive battery not working.
