Surgeon: "We are almost done, hand me those Energizer Batteries and I will put those in and close her up."
Nurse: "We are out of Energizer Batteries, so I picked up this 25 pack at Big 5 for half the price, see they have a cute little turtle on them."
Surgeon: "Okay, well I guess they will have to do.... a turtle? I wonder what that's suppose to mean."
.....and that is how it went. My battery life is about one hour, then I need two hours to recharge. I sure hope it gets better soon.
