Every rechargeable battery deteriorates thoughout it's life of usage. may be it's time to buy a new one. Sometimes the terminals on the battery get in touch with metal things and short the circuits within.

jpierre's solution (in another thread) was right on the money. Touch the positive (+)end of the 9v battery to the positive (+) end of the camera battery.Leave them touching for a few seconds (10 seconds should be more thansufficient). Seems these lithium-ion batteries are subject to a'digital memory.' Subjecting it to a volt surge almost three timeshigher seems to clear it.

In short, it works like a charm.

My mom and stepdad had the same problem less than one week after I bought it for them. I called Casio Technical Support, and they were awesome! They just needed the cradle number and the serial number to send them a new battery. I was on the phone less than 5 minutes.

you now can buy chargers to replace lost ones, i work in a camera shop and sell a brand called Hanmel. they do a range of the most popular brands of camera chargers, just check the back of the hamnel packaging it to see if it it compatable with your battery

I found this while trying to solve my exact same problem.. It worked for me after about 7 times. Some other people on the site said it worked for them after 20 times. Good luck!

My NP 20 gave me the flashing red light of death and I got Casio to replace it. Then I had the same problem with my second NP 20 so I dug around for a way to fix it and I found the following advice on a site called FixYa. It worked instantly and I didn't risk ruining my battery.

I had the same problem as this.
what i did was...
i kept putting the battery on the charger then took it off as soon as the red light came on.
i did this about 6 times.
doing this puts a bit of charge in the battery each time before the charger starts to flash.
after the battery as got enough charge in it it can start to charge.
hope this helps.
