I would die for a few extra hours. I'm usually lucky to get 10.
with all the things i have done to extend my battery i can get over 12 hrs with the stock, i get almost no signal at work due to the heavy amounts of concrete, brick and metal making up the building. today the first day running chevyno1 1.25 ULV i usually leave after being there for 10 hrs and the battery is at about 5%, today i left after 11 hrs and it was 20%.
when im somewhere with good signal, i can get around 14-16hrs on the stock. im hoping the extended will give me at least 24 hrs.
