Re: Problem with the battery

I just had this happen to mine too. I think this is a design problem with the camera/battery combination. My camera has a lithium polymer battery (most do now). Lithium polymer (lipo for short) batteries should never be allowed to discharge below about 2.75 volts. Letting the battery discharge below that level will actually permanently damage the cell.

In order to keep that from happening, the device that uses the lipo should have protection circuitry that prevents the battery from falling below that level. I think this is where the Casio camera may have an issue. I found that if I left the battery in the camera for about a month, I was not able to charge it! Lipo battery chargers are more sophisticated than typical charges because lipos need to be charged in a specific way. The first thing a lipo charger does is to check the voltage of the battery you insert into it. If it is below a critical minimum voltage, it will not even charge the battery (Casio charger blinks red continuously).

There are a couple tricks you can do to get the battery to charge, but that's not the important thing here. I think Casio needs to address this issue with our cameras. It would be nice if we could just update the firmware in the camera, but I'm not sure we can do that. I intend to contact Casio to see if they know anything. Based on how many posts like this I have read, I bet they do.

Good luck to use all.

Hi there,

When the battery is in the charger it flashes red & won't charge, have no idea what problem is! Have casio exilim lithium ion NP-20 battery & a casio exilim 7.2 megapixels camera. Can't turn camera...

I called casio and they told me that when you have a red flashing light on the charger it means the lithium battery is no longer any good. They offered to send me one free of charge. It's been several weeks and I have yet to receive it.

Battery not charging

I gave my wife also one of the Casio Exilim cameras. She doesn't take a lot of pictures. But so far the battery has not failed us. There might be a chance that your battery has died on you. I suggest you go to Casio and ask them to test the battery. I'm guessing it is the battery that has conked out. If it isn't then you need to have Casio check on your camera.

Not turning on.

this mostly happens due to the motor failure or loose-connection of the wire of motor of lens. or some thing must be stuck inside the shutter or motor..

It can't be switched on

What you all need to do is contact Tech Support and tell them you're having trouble with your battery. Casio will send one to you free of charge that has been tested and should work.
