Hello , I am after a prius plus 7 seater 2012 used car ; My question is Is it possible remove the hybrid battery form the car and not use its hybrid ability at all for the rest of its life time and use only its petrol engine.
hybrid battery turns the engine over. that being said, a major modification like a corolla drivetrain swap or something might work
No you can't disable the hybrid battery. It starts the engine, t is the "alternator", it makes the transaxle work and much more.
