The whole camera outfit is only a few dollars more.
2 Generics for $8 worked for me.
Also, batteries on my older Casio lasted forever, and was able to take more pics per charge.
Rating: - Bad product
On my 2nd Casio NP-20. This is a very poor product. Will charge for a while and then suddenly will not hold a charge. Casio makes a decent camera but their batteries are garbage.
Rating: - OK until they fail - (frequently)
I'm on my third "genuine" Casio battery in one year. The $5 generic batteries seem to work just as good. Contact Casio for warranty first- they'll send out a new battery and acknowledge that they frequently fail
Rating: - Good camera, bad charger
We have three of these cameras mostly because they are thin and easy to put in our pockets or my daughters small purses. They get alot of use and the only issue we've found is with the charger. We thought we were having battery problems, but the issue was really with the charger. My advise...make sure the charger red light is blinking before you walk away and think you're charging your battery.
