There are lots of battery threads but I am trying to get to the point with this one. Would someone who has had a cheap battery for a few weeks comment with suggestions? I know it won't be as good as an expensive one but I am just looking for a backup battery for traveling/flying. It doesn't have to be amazing but I am looking for someone who has had a good experience with one of the many cheap batteries out there. And it seems like after the first week, the honeymoon is off. some ebay prices shipped: 2x 1300 mAh plus charger $10 - Item # 170522089513 2600 mAh plus cover $11.50 - Item # 250669240800 2x 2600 mAh plus cover and charger $22 - Item # 220629106669 Bad experiences welcome also!
