Pentax D-LI88 Li-ion Rechargeable Battery for Camera Pentax Optio WS80 / W90 / P70 / P80 / H90 (Electronics)
great to have 2 batteries for my camera because it is not easy to walk with charger .... especially ride or a concert !!! j 'have one in my camera and the other as a backup in case ... because if you take the video, the battery will discharge faster.
