What’s the difference between the Sanyo Eneloop Rechargeable Batteries and regular rechargeable batteries, you ask? They retain their charge longer. Bet you didn’t know that when you charge a rechargeable battery, and you don’t use it, the charge drains?
I’ve had it happen one too many times. Of course, after charging regular non-Eneloop rechargeable batteries and storing it for the next time I need to use it, and then needing to use it, they held no charge. But of course, I said, these batteries were probably never charged. Which of course was not true, I just forgot that I did charge them!
This is especially handy if you need to store extra batteries for your digital camera or flash in your photo bag, and knowing that it will reliably hold a charge when you need it.
