How to Clean Battery Acid on a Nikon Speedlight Flash

Save

When an electronic device is placed in storage or not used for a long while, the batteries can corrode and begin to leak acid. Once dry, the acid is white in appearance and powdery to the touch. Left to harden, the acid can stick to the metal contacts inside the battery chamber and prevent the flow of electricity. If your Nikon Speedlight flash unit is suffering from battery corrosion, use household materials for quick cleanup.

Things You'll Need

  • Tweezers (optional)
  • White vinegar
  • Microfiber cloth
  • Eraser
  • Replacement batteries
  • Slide open the battery chamber cover on the left side of the Nikon Speedlight.

  • Pull out the two corroded batteries. If the batteries are stuck inside the chamber, use tweezers to chip away some of the dried acid and grasp the cells more firmly.

  • Moisten a microfiber cloth with white vinegar. Push the cloth inside the chamber and rub away the dried battery acid. Also clean away dried acid from the underside of the chamber cover. Apply more vinegar to the cloth as needed.

  • Wipe the inside of the chamber dry with a fresh microfiber cloth. If any acid has leaked onto the outside of the unit, wipe it off with the moist cloth.

  • Rub the metal contacts inside the chamber with an eraser to remove any rust or remaining corrosion. Also rub the contacts on the underside of the chamber cover.

  • Insert fresh batteries into the Speedlight's chamber and slide the cover closed. Most units use two 3V CR123A/DL123A batteries for power.
