Review title: Don't hold a charge as well as I thought
Product review: I was a little dismayed that the advertisement for these batteries doesn't state that you HAVE to have the special "15 minute charger" to go with the "15 minute batteries". The regular charger takes them overnight to charge, just like every other rechargeable battery, and even then they don't hold a charge for very long. With normal use they last maybe a week. Granted, we have been using the flash a lot so maybe that's why.
