I charged my camera with a different charger - Kodak EasyShare One Digital Camera

Different charge? Was it the same output as the original charger. If it was not it could have damage the camera.

I use one universal charger (GP) for 4 different Photo Camera's and one video camera. All batteries are charged correct. On my charger I need to set the contact points correct for the different batteries, but after I put one on the chatter it becomes charged in a few hours. (I don't need to look for voltage nor for where the plus and minus go.
My advice? Google for universal battery charger for camera's and buy one. I think the charger will serve your next camera too.

I had a similar problem with the P10 not charging via USB, I purchased mine second hand so it came with no charger just a USB cable. I assumed it would charge by the USB cable but it did not, the red light flashes but doesn't charge. Luckily I have an external battery charger for a different camera i got some years ago that takes a similar battery , the P10 battery didn't fit properly so I had to place it at a 45 degree angle into the charger making sure the outer contacts were lined up properly and taped it into place. After an hour it was fully charged and the camera is working fine. The charger is a 4.2 volt charger. New external chargers can be picked up on ebay cheaply

The A3100 comes with a separate battery charger. The camera does not charge with a USB cord.

The specs on this camera say that it has an external charger. Sometimes the usb cord will also charge the camera, but not all the time (depends on manufacturer). You will have to contact Polaroid, most likely, unless you can find a generic charger at Best Buy, etc.
Here is some information about the internal charger of the camera from redpowers.com:
The Lifespan of the Polaroid T737 Battery The life of a rechargeable battery for Polaroid T737 Digital Camera operating under normal conditions is generally between 500 to 800 charge-discharge cycles.
This translates into one and a half to three years of battery life for the average user. As the T737 battery begins to die, the user will notice a decline in the running time of the battery. When a battery that originally operated the device for two hours is only supplying the user with an hour's worth of use, it's time for a new Polaroid T737 replacement battery.
Is it Possible to Upgrade the Digital Camera Battery to a Newer Chemistry? NiCad, NiMH and Li-Ion are all fundamentally different from one another and cannot be substituted unless the Digital Camera has been pre-configured from the factory to accept more than one type of rechargeable battery technology. The difference between them stems from the fact that each type requires a different charging pattern to be properly recharged. Therefore, the Polaroid T737 Digital Camera internal charger must be properly configured to handle a given type of rechargeable battery.

They didn't explain how to configure, but it should be in the software menu of the camera.

I found batteries for this camera on google, but couldn't find a charger. Looks like if you have the right type of battery, the internal charger (through the usb port) will work.
Good luck, thanks for using FixYa, and hope this helps.

so it means the battery might be old and not holding charge. or else some defect in battery charger may let your battery not charged at all. SO try using some other same type battery to your camera and try charging with some other different charger. Find out which one is having problem and replace them
Thanks

What do you mean by it does not want to charge. The battries are bad. You must always charge batteries with the charger which came with it. If you chrged your batteries with a different charger than came with your camera, your batteries are damaged.

Try with new batteries. Good luck

Ther may also be a fault with the camera body. Seek advise for a Nikon repair centre.

If your camera appears to be in working order, your charger or the power outlet may have an issue.

With all connections intact,

1) Please try to connect the charger to a different power outlet and try again.

2) If the charger doesn't appear to show any indications of charging, try with a different charger.

3) If the charger works fine, there may be something wrong with the battery - or the camera. In such a case, please consult an authorised service center for a resolution.

Thanks!

Check your batteries. Your batteries may not be fully charged. One reason may be that you are charging batteries on a different AC Voltage supply, than what the charger is meant for; eg, charger expects 240 volts and you are charging with 110 volts.
