How to Charge My Nikon COOLPIX S3100

by William Pullman

When you're taking pictures with the Nikon Coolpix S3100, you don't want to have to worry whether the battery is properly charged. The S3100's rechargeable lithium-ion battery is charged using the supplied mini-USB to USB cable and the AC adapter or a computer. Nikon designed the S3100 with a charge lamp that indicates when the camera is charging and when it is finished. The charge time when the battery is depleted is approximately two hours and ten minutes.

Step 1

Lift the prongs on the supplied AC adapter upward with your finger. Press on the side of the prongs to ensure they're fully extended.

Step 2

Plug the small end of the mini-USB to USB cable into the mini-USB port on the bottom of the camera, and then plug the USB end of the cable into the USB port on the AC adapter.

Step 3

Plug the AC adapter into a power outlet. The charge lamp, located to the right of the LCD screen, blinks green while the battery is charging.

Unplug the mini-USB to USB cable from the camera when the charge lamp turns off.


  • The Nikon CoolPix S3100 can charge using a computer connection in the event you don't have access to the AC adapter. To charge the battery using a computer, plug the mini-USB end of the cable into the port on the camera, and then plug the USB end of the cable into a USB port on the computer. As when using the AC adapter, the charge lamp blinks green when charging, and turns off when charging is complete.


  • If the charge lamp flickers green, check that the AC adapter is properly connected to the camera. Another cause of the charge lamp flickering is the ambient temperature of the area where the camera is charging. Only charge the battery indoors with an ambient temperature of 41 to 95 degrees Fahrenheit.
