I can only say that QC (or lack of) is an issue I've encountered as well. I've received several batteries which were DOA. The company I bought them from gave me a make-good offer ... sent them back at my expense for exchange, and they're throw some freebies in the bag to cover my postage. Doesn't cover the inconvenience though. There's definitely room for improvement.
But, as to your original question: I don't see how it could be done, sorry to say. If it craps out within the warranty period, get an exchange. If it lives a normal expectancy ... who's to complain? You just buy another one. Batteries and atomizers are consumables. They don't last forever, and you should take that into account. Always have spares on hand, because there's no way to tell when something is going to go belly up.
I thought someone who owns an eGo PT would've chimed in by now. But, again, it is essentially a battery, and they don't last forever.
