Kodak easyshare dx6490 charger indicator light is on but battery wont charge

mine did the same thing, only it hadn't been dropped. Turns out, the battery went bad. The repairman said that the life of those batteries is only about 3 years average. He also said the average lifespan of the camera itself, with frequent usage, was only 3 years! I am still hoping to get the auto focus fixed on mine though. I sure did love that camera.

Hi: This is a long shot, but I had a similar. It would start up, but lense would not extend. Secret was that it wanted the date re-loaded. They have a small internal battery to keep the clock going when you remove the main battery to change it. Many people never do this, just set it on the dock and recharge it. But IF you remove the main battery, and IF the camera is...elderly...the small battery has died and the clock has stopped and the camera has to know what time it is to run. Once you tell the camera what day it is (look in the viewfinder- it's asking for it) she'll fire right up.
I hope this works. These cameras are great. I cna change batteries in about 5 seconds now- practice. If you're fast enough, it won't lose its memory. Joe

There was an issue with the 4000 series and the NiCd batteries I remember that had to do with the contacts in the camera.  The charging circuit is in the camera so you have to make sure that the battery contacts are clean, both on the battery and in the camera.

My Z760 does the same thing. When that happens I run the battery completely down by taking pictures until it shuts down. Then when I put it on the dock it charges properly. Don't leave your camera on the dock all the time and don't try to always keep the battery fully charged--instead it will develop memory and think it needs to be fully charged to run and will give you a low battery signal earlier than it should. Wait until you actually get a low battery signal before charging and it should help, but mine will still give me the red light sometimes. Then I run the battery out like I said before. I hope this information helps. :-)

You can test charger with a voltmeter or test light. If it has no power, that it is battery pack, You can test battery same way.

amazon.com or newegg.com would carry them. Even ebay
