Kastar 2-Pack EN-EL20 Replacement Battery

Good batteries that got exactly like OEM. You can recharge themsny times before they start to lose capacity. They seem stable. Eventually like all rechargeable batteries they will swell a little and then their lifespan is pretty much done. These batteries have lasted several years. I completely got my money out of them. Will buy again. Good batteries, long life.

I found these batteries to charge fully. They fit and work well with my Nikon. Would recommend these over the oem batteries due to the cost.

Be prepared to take a roll of duct tape on your outing along with your spare batteries. As another reviewer stated, these batteries are thicker than the originals, and the person used some small piece of plastic to get it out, but i wasn't keen on sticking anything down the battery compartment so i used duct tape to get the sucker out. The tape worked fine for me, just yank it like a loose tooth.. but not as hard as pulling a lawn mower cord .. Won't give rating for battery life as i haven't used them long, plenty of folks say the last long enough though.

These batteries work wonderfully and hold a charge for a long time! I was greatly satisfied with the strength and quality. They also come in a very nice heavy plastic cover to insure they are kept safe when not in use!

Works well

I have been using Kastar batteries for my Nikon and Panasonic cameras. They are affordable and work great for the price. I used them for my Nikon Coolpix P1000 camera.

Great battery. Fits my Nikon Coolpix P950 perfectly. Charge lasts at least as long as the original Nikon battery if not longer.

Works really well as a backup battery, and the battery life seems fine, although I haven't paid close attention or measured it. The only complaint so far is that it doesn't give me any warning that its being depleted or low. It just suddenly dies. That would bother me if it were my primary battery, but as a backup its fine.
