Nikon Coolpix battery will not charge

Are you using the Nikon charger or a substitute ?

Battery is broken, replace the Nikon Coolpix 3100 Digital Camera Battery Bar: http://www.2deals.net/Digital-Camera-Battery/Nikon/Nikon-Coolpix-3100.html

try leaving the camera on to drain the battery down, then try charging it again.. or could be a bad battery

Read page 16 of the manual. Do not use any other charger with this camera. Are you sure you have the battery inserted correctly? When trying to charge, does the green light blink? If so, when it stops blinking and turns off, the battery should be fully charged. Do not attempt to turn the camera on while the charger is trying to charge the battery.

Charger flashing red indicates the battery is still not full and is in the process of recharging.
Red light steady indicates your battery is fully charged and ready to operate with your Coolpix 5000.
When red light is off it indicates there is no battery inserted or the charger is not pluged in.

The S220 uses the EN-EL10 battery. The camera does NOT incorporate any charging circuitry, so connecting it to a computer actually drains the battery. In order to charge the battery, you need the MH-63 battery charger or a third-party equivalent.

If you need a charger, you can order one from your local Nikon dealer or from http://www.nikonmall.com

The flashing red light is warning you that the shutter speed will be too long for handholding the camera. Put the camera on a tripod or other stable surface, and/or use the flash.
