Anyway to hasten up Model S battery failure?

I've got a Model S that has around 9 months of warranty left on motor and battery. I've done around 300,000km and the battery is definitely not as good as it was! It claims rated range of 494km (typical 390km). Is there any way to get the battery to fail in the next 9 months? Would be good to do as the car suffered insane depreciation and a new battery with free charging for another 300,000km would suit me nicely. It's the AWD 90 model.

Sorry if people consider this unethical, I'm pretty sure Tesla can live with it and the money they got for this car originally helped propel their company forward.

Thanks!
