Does revving in neutral charge battery faster?

The battery will charge faster if you rev the engine faster. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator.

Does revving help battery charge?

Can you redline a CVT transmission?

It won't go to redline and shift gear. Likewise, it will constantly stay at max power RPM because that's the fastest way it can accelerate. This is what causes the CVTs to be so efficient. They can constantly use the engine as efficiently as they can.

What happens if you accelerate in neutral?

Is Accelerating In Neutral Bad? As a first step, the engine runs at its lowest RPM when in neutral gear. As a result, the engine gets less cooling, which can result in bearing failure due to heat and friction, which can result in engine failure.
