Lost my original charger so bought this one.Turns out you have to put the battery in upside down to line up the little metal +/- chargers.Not only that, but the battery won't make contact with the charging elements without shoving several thick pieces of paper or cardboard into the front where there is a little ridge to hold it in. Doing this it finally worked but it's a hack to get it to work.Definitely wouldn't buy again.
