The most current Wasabi EN-EL15 - tan with an embedded USB 'C' charging port (replacing Nikon a,b and c versions) is the best EN-EL15 battery I have used, including Nikon's own, based on performance, reliability and value vs cost.
I've shot Nikon since 1965 (I'm old). Digital since the early 2000's. My first Nikon digital camera was a D100. I've been using Wasabi batteries more than ten years.
The most current version, as mentioned, tan color with a USB 'C' charging port, is my EN-EL15 battery of choice, based on three factors:
a) I've used several brands of third-party batteries over the years, in a variety of Nikon bodies. The Wasabi 'tan' is the only one I've used with the same or very similar capacity as the Nikon-brand battery. I've cut open other 3d party brands and the cells inside are stamped with LOWER amp-hour ratings than the label on the outside - a cost-saving (and deceptive) sales tactic. In my experience, the Wasabi is very close to the capacity of the Nikon-brand battery (90-100%) at around HALF the selling price.
b) The Wasabi 'tan' EN-EL15 is, as far as I have determined, recognized by and fully compatible with any Nikon body using the EN-EL15 (a,b or c), DSLR or mirrorless. This overcomes Nikon's attempt to restrict Nikon shooters to Nikon-brand batteries (sold at significantly higher prices). This is especially significant with Z-series (mirrorless) bodies, which by necessity, replace the optical viewfinder of older Digital SLRs (DSLRs) via powering the image sensor and an electronic viewfinder. This necessarily means way less battery life - as little as a quarter that of Nikon DSLRs. Spare batteries become mandatory instead of just a good idea whether you're amateur or pro. With similar capacity at half the cost, and full compatibility, the Wasabi 'tan' provides enough batteries to cover a kid's sporting event, a wedding or a full day / night of vacation pictures without breaking the bank.
c) The Wasabi 'tan' battery has a built-in USB 'C' charging port. To my knowledge, no other EN-EL15 - including Nikon's own - can be charged from any AC or vehicle charger with a USB 'C' terminus (USB 'A' to 'C,' 'C' to 'C' or hardwired 'C' male connector), If you have a charger providing USB 'C' output, you can charge / recharge the Wasabi 'tan' from a wall or vehicle charger while continuing to shoot with another battery in-camera.
The Wasabi 'tan' battery does, of course, charge in any Nikon body providing that ability (many newer "Z" models). But you aren't limited to that or a Nikon-type batter charger. Use your phone, tablet, car or any other charger providing a USB 'C' connection, which is the defacto and EU standard moving forward.
No other batter I'm aware of, including Nikon's own, provides Nikon users whose cameras use the EN-EL15 form factor, these benefits.
NOTE: I have no connection with Wasabi Power other than a satisfied customer. No remuneration, including free / discounted product or any other benefit has been provided to me.
This review is provided because after lots of research and testing I have found no other battery with the capacity and compatibility of the Wasabi 'tan' EN-EL15.
HIGHLY RECOMMENDED.
