“Wanted to let you know the Nexcell battery worked like a charm. My Prius is better than I've ever experienced. It seems like I can't drain it to 0%, even if I tried. - PriusChat.com

Finally got to California and tested pack over Siskiyou pass... It's a totally different car at the highest elevation of I-5 when it's down at 2-3 bars. Still lots of power! So much different than a worn out NiMH that runs out of power and the engine needs the accelerator nearly floored with no speed or power to keep going. I was so impressed my first thought is you should brand it as such. Call it the "Hill Climber Lithium Power for Prius" Rush hour in Portland in EV mode was almost as awesomely impressive as well - YouTube
