Sorry I'm a bit late in replying to your earlier question... I recharged that particular battery once a day mostly and on some occasions twice. The other two I ordered that day, one went to a friend who charged it every other day or so, and the other was a back up for my original and was used whenever the other was charging. I'm pretty sure that the battery would have lasted longer if it hadn't been as abused as it was. It was the only one to suffer from falling down a set of concrete parking garage stairs and a dozen or so falls from a table onto tile floor. Dang thing took a beating and had scratches and dings galore before it finally gave up.
