[nfbwatlk] braille note battery question

[Lauren Merryfield]

Hi,
My braille note's battery went clear down and I've had it recharging for over a day and the level is only at 23%.  I don't know why it is so slow at recharging.  How do I know if it needs a new battery or not and where to get one, if I do need one.  
Thanks
Lauren
I think laughter may be a form of courage. As humans we sometimes
stand tall and look into the sun and laugh, and I think we are never
more brave than when we do that.
