It's a much cheaper alternative to the Sony brand battery. Works just as well. The only problem is my camera, DSC-WX5. It drains this battery quickly when using flash or video. So I am forced to carry 3 of these batteries when i go out.
does this work with the sony DSC-Wx80?
I haven't a clue I would suggest you ask Sony
How long does a full charge take?
I usually charge it for an hour and a half. And the charge will last all day.
