Nikon 990 & Nikon 3100 Battery Door Repair Kit

The battery doors on the Nikon 990 & 3100 cameras are notorious for broken latches. We purchased four Nikon 990 cameras for the StonePics photo project and have taken nearly half a million photos with them. Unfortunately Nikon did a poor job designing the battery door latch using plastic where metal was needed. Eventually all four of our cameras developed broken battery door latches. Rather than paying a Nikon service center $100 per camera for the same defective design, we have designed (US Patent Pending) and manufactured a solid work-around for the problem.

A stainless steel metal plate keeps the battery door securely closed and is held in place by screwing it into the tripod mount hole on the bottom of the camera.

We offer two sizes depending on your camera model:

  • large - for Nikon 990 and some other cameras with a battery door sized for four AA-batteries;
  • small - for Nikon 3100 and some other cameras with a battery door sized for two AA-batteries.
