Summary: Received the battery from the company in a timely manner and it worked very well after charging it. I've only had it for a few months, but have had no problems with it. The other one lasted several years and a lot of that was in a cold weather environment used to take vids and pictures of us ice climbing, winter mountaineering, etc, with no problems at all.
Summary: My original Casio battery died after about 13 months. I'd say that's pretty convenient timing on Casio's part, since my warranty was for 1 year. I tried both of the methods for "jump-starting" it I read about here: repeatedly putting the battery on the charger just until the red light turns on, then removing it, as well as using the 9 volt battery. I couldn't get either of those methods to work, so I just bought a new from Amazon.
Summary: The only reason I give it 2 stars is because it actually worked for a while. Initially when I bought my camera, the casio li-ion NP-20 battery that came with it worked for just 13 months. Considering that my warranty in Belgium was just 12 months, I had to go to a service center that could not explain what was wrong with my camera and why did it stop working even though it was fully charged before it dropped dead.
Summary: I have 2 Casio cameras that I love for their quality and small size. The worst photo is the one you didn't take because you don't have a camera with you. The batteries for both of these models are getting harder to find because there are newer camera models out now and because (I'm afraid) there are fewer people who need them. But as usual, J&R always has what I need and I count on them to be the source for these hard-to-find items.
Summary: Instead of trying to strap a car battery to your camera try using the charger to "reboot" the battery. If your charger is blinking and not charging, see what gianna says: "By Gianna "Gianna" (UT) - See all my reviews 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.
