Canon shooters, these little battery covers are more useful than you might think. It's a 3-pack of protective covers for your LP-E6 or E6N batteries (they're the same size). Fits Canon EOS cameras like the 5D Mark II, 5D Mark III, 7D Mark II, 5DS R - basically any Canon that uses those batteries. They're brand new, unbranded/generic, but they do the job. When your battery isn't in the camera, these covers protect the contacts from dust, moisture, and short circuits. Just pop one on when you're storing batteries in your bag. Super simple but prevents potential problems. No MPN or UPC, but they're just basic plastic covers. If you have multiple LP-E6 batteries (and most serious Canon shooters do), having covers for all of them keeps everything organized and protected. Much cheaper than replacing a damaged battery because the contacts got corroded. Throw them in your camera bag and use them whenever you swap batteries. Little accessories like this show you take care of your gear. Whether you're a professional or enthusiastic amateur, protecting your batteries makes sense. Three covers means you can protect three batteries - perfect for a typical shooting setup!
