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.
