FirstPowerEN-EL15 /EL15a/EL15b/EL15c Batteries 2-Pack and USB Dual Charger Compatible with Nikon Z6 Z7 D750 D850 D7000 D7100 D7200 D7500 D500 D600 D610 D780 D800 D800e D810 D810a Cameras

Over six months, I've been super pleased with this purchase and would absolutely buy this battery/charger set again.I first chose this brand for 3 reasons:1) Great experience with previous purchases of FirstPower batteries for cameras and vacuums.2) Firstpower warranty and customer service. Just do a search and you'll find that when there IS a problem, they respond and stand by their products, even beyond the warranty period.3) Great value. Not the absolute cheapest, but much cheaper than OEM batteries and chargers.4) Charger design: Compact, lightweight, charges 2 batteries at once, simple charging indicator lights, no bulky cord or transformer, and USB flexibility (I can power the charger from a USB multi-charger, very convenient when traveling).I bought two of these battery/charger sets for my two different Nikon camera bodies and just used them all on a month-long safari where I was swapping and charging batteries daily. Excellent performance. Thrilled with this purchase.

I bought this for the charger alone because I had misplaced my OEM charger, and needed one for traveling. I had no idea that the price included two batteries. That's just extra for me. The device connects to any standard USB C cable that you have. It also has a port for the smaller micro USB cable that is now almost obsolete. I didn't even use the cable that came in the box. That makes it so much easier to use it on the road or here at my desk where there is always an extra USB C cable.

So I purchased two Nikon zf last year when the cameras first hit the street. I put off buying a second set of batteries because only genuine batteries worked and they are expensive in my opinion and I haven't truly needed a second set.So far I have never actually drained a battery on a photo shoot so far. But I didn't come for the batteries, I wanted to save wear and tear on the usb-c connection and decided to go for an external charger.So many of these chargers come with batteries that I thought I would research if any third party batteries worked with the Zf now that some months have passed.Well this brand came up as something that works with the Zf. So someone figured how to get around this problem. I got the charger that I wanted with bonus batteries.The batteries that came with this charger took about 45 min to charge up. I put them in my Zf and they work fine.I just put my original Nikon batteries in and they are charging up.There is no charge percentage indicator. It's super basic. When you plug the unit in, both LEDs are green and turn red when you insert a battery, they turn green again when the charge is done.It comes with a little usb-c cable and that's it. I use my own cable.Its 7-25-2024 as I write this, any issues I will update. No news is good news.So here's how I will use these, genuine batteries only for the shoot, third party only used if original is depleted. Hey better safe than sorry.

The price of the 2 extra batteries and charger is unbeatable! This unit chargers must faster than the MH-25 quick Charger and includes 2 extra batteries for a cheaper price! They worked perfectly for my Nikon Zf camera.

UPDATE: Full Disclosure-testing done using Nikon D780 "Hybrid" DSLR using Nikon OEM EN-EL15a, EN-EL15b, EN-EL15c and First Power EN-EL15 3rd party batteries. FirstPower reached out after my first review and 100% standing by their products, they sent a complete new package to replace 1 defective battery out of the 2 pack + charger I originally ordered (see original review below). Mind you, I did not ask for a replacement as I was satisfied with my 1 good battery at this price point. KUDOS FIRSTPOWER! So curious, I decided to grab a handful the ten EN-EL15 series batteries accumulated since buying a Nikon D750 in 2015 to compare against the FirstPower, replacement batteries over a few days of shooting and video recording events. My original & oldest EN-EL15's may be toast as they were good for probably an average of 1000 +/- 100 shots (also depends on if using a zoom lens and zooming in and out). My more recently accumulated EN-EL15b's & c's were good for 1900-2230 shots using prime lenses, no flash. I only tested one of the brand new, FirstPower EN-EL15's fully charged using their provided charger and to my surprise, I was able to click off 2193 shots using a prime lens and no flash! That's much better than the 75% of OEM battery shot count in my unscientific review below. This means that in my use, a brand new, fully charged FirstPower EN-EL15 lasted longer than my older, Nikon, OEM EN-EL15 and 15a's, and lasted as long as my OEM EN-EL15b's and c's. FYI; the earlier Nikon EN-EL15's are 1900mAh and the EN-EL15c's are 2280mAh. The FirstPower EN-EL15 is listed at 2300mAh. If I remember, I'll post another update after I've cycled the FirstPower replacement EN-EL15's through a few charge cycles to see if they last as long as when brand new. So my overall impressions are that 1) FirstPower fully backs their product and 2) a brand new, fully charged FirstPower EN-EL15 replacement battery lasts as long as my Nikon EN-EL15b and EN-EL15c batteries that are not brand new! Definitely satisfied, especially at this price point!ORIGINAL REVIEW: ("Budget Batteries, Budget Performance"), One of the two EN-EL15 batteries works fine and seems to hold a charge and last about 75% as long as Nikon OEM batteries; however the other unit failed after initial charge and use. It would not charge back up using the battery charger included not my Nikon battery charger. At least I still use the dual battery charger to charge up multiple, 3rd party batteries at once. I'll keep charging Nikon OEM batteries using the Nikon OEM charger. As an event shooter, I go through a ton of batteries covering a single event so always have 4 to 6 on hand!

Good charger and I'm really happy with it. Charges two D7500 compatible EN-EL15 batteries via USB C decently and those batteries last a while.

Worked perfectly. Batteries fit my camera like the original.

They arrive with no charge is the only negative I can say. I really like the dual usb input. Micro type & "C" type USB input jacks for power. Green lights for charge complete makes it idiot proof. Very compact size.
