BESTON EN-EL15 EN-EL15a EN EL15b Camera Battery Pack and USB Dual Charger Compatible with Nikon D750 D7200 D7000 D7100 D7500 D750 D800 D810 D850 D500 D610 Camera Battery (2-Pack)

so far, i am hedging my bets, and saying they are Almost as good as the Nikon OEM battery.Actual useage so far, they seem to be AS good. but, only having them for a couple months, i hate to swear they are just as good.charger works fine, isnt too hot, charges the Nikon OEM battery with no issue.definite cost savings, and a must if you travel, hike, wander around and end up using the built in flash more than you intended, which will use up your battery some fair amount quicker.I got these shortly after i bought my D7500, simply for that reason, better to Always have an extra batt on hand, and not need it, than need it, and not have it.missed shots are forever in some cases ! !

These batteries work but the charger that came with it does not work. I thought to begin with that both batteries were faulty but after a charge from the Nikon charger they were good to go. Battery life is ok,not as long as the Nikon battery.

These batteries and charger are great. Save time and money. Bought one for a nikon d7500 and my nikon d520

This charges battery and the batteries last longer than my OEM charger. The digital statuses are a great touch.

As a busy real estate photographer this has been extremely helpful charging on the go.

You wouldn’t be able to tell it it’s t a native battery

Don't waste your money on these batteries. Cannot get them to charge to more than 25% of capacity.

Got it on Amazon 'overstock' section for <$20. Charge it up, plug in my old D610, the battery is not even full. Took 60 pictures, half the charge was gone. Battery started blinking red after taking 200 pictures. Try the other battery, same thing.Reversed back to my old old original Nikon battery, did exact same test as above, still full charge.You be the judge.
