Good quality. Batteries are good and charged to full

Everything arrived quickly and works great. Haven’t drained batteries yet to know how long they last but very happy with purchase. Bought to replace Nikon camera battery and charger.

The charger is compact compared the the original charger; giving you more room in the camera case. Another advantage is that it's a USB plug vs the 110V. Charging speed is twice as fast now that you can charge both batteries at the same time. All in all, well worth the value for the money.

Not factory batteries but work good. Greylrice for what you get

I like that the charger has led lights that show the charging progress.The batteries are fine.

Battery’s are an excellent replacement for my Nikon D50. They charged fast and hold a much longer charge than the original battery’s. Good price good product!

This is my second order. This charger is great for my Nikon DSLR camera. Easy to use and travel with. Works perfectly.

First, these batteries work fine in my Nikon D300. They are ever so slightly smaller than the official batteries, but I don't think it makes a material difference. The fact that it comes with two batteries, and a charger for this price is an incredible value in comparison to the original Nikon. The charger requires a USB Type A(via the included cable) or USB C power connection and there's no AC adapter included. You can use any AC adapter for other devices, phones as long as it supports at least 800ma.I ran three different tests on the batteries using the included charger, waiting until the light turned green. The first two tests were a static constant current load of 300ma for the duration of the test. The cutoff voltage for the test was 6v, or 3v per cell, which is the lowest I'm comfortable going. Datasheets for these type of cells say 2.5v-3.0v for the lowest safe discharge voltage. Because the rate of discharge can affect the total achieved capacity, I also ran a 0.2C test, which is a 460ma. A 0.2C test usually allows for the highest possible capacity. The results were the same for all three tests.As you can see in the included images, the batteries tested to 1669, 1682, 1680 mah. The 300ma tests both ran for about 5 hours, 35 minutes. The 460ma test ran for about 3:40.While for all practical purposes, you'll probably get plenty of battery life with these in your camera, these are clearly not 2300mah cells. They are also 12wh batteries, not 17wh as printed on the case.
