Query: Doesn't maintain charge

While I haven't had the bad luck of less than ten shots per charge, I do find that I am charging after 20, give or take a few depending of the use of red-eye reduction, etc... I do wish I had researched the battery issue a bit more before purchasing these. I know the first set I had, which were lithium, lasted a LOT longer and I was surprised at the life of them.My advice, read a few of the reviews before you buy. And don't expect these to be long life batteries.
