My second controller that came with Wii play battery has just died after only a week. This one came with the Panasonic batteries. I think I have used it for about 15+ hours, maybe more. The indicator shows full charge for the whole week till yesterday it started giving low battery warning. Today, it kept turning off. However, the controller that came with the console seems to be still running strong at full charge according to the indicator. This one came with the Maxwells batteries. I believe I use both controller almost equal amount of time. How long does your original Panasonic batteries last compared with the Maxwells?
