SMALLRIG EN-EL25 EN-EL25A USB-C Battery for Nikon 1250mAh 1.75H Fast Charge

Great drop in replacement. Not sure there's any additional battery life, but its a drop in replacement for cheaper than the OEM part. The charging with a USB-C cable should be a nice feature, since you can't charge through a Nikon Z30/60/FC's USB-C if the battery is totally dead it'll be good for field use. Only downside is that charging the battery with the Nikon charger, it never shows as full. Not a big deal, honestly.

I was a bit hesitant to purchase these given the number of poor reviews that mention having them fail after just a few uses. I bought two, figuring I'd take a chance. I've charged each one at least three times and used them anywhere from 25 to 90%. So far I've had only good results. It's a lot nicer charging with a simple and ubiquitous USB-C cable than keeping track of the OEM charger, which I invariably forget to bring with me when I travel. And I'm also getting at least 50% more shots per charge than the OEM batteries. Somewhere in the range of 400+ shots with 33% battery left vs 300-325 and draining the OEM. Fingers crossed they continue to perform well.

Bought in 2024, used on a trip. Charged it no more than 3x overall. Sat in the camera for 2 years until I needed it. Went to recharge it, but only the red light comes on, even after trying multiple chargers, cables, and leaving it to charge overnight. It never even gets warm, so I know something is very wrong. Never exposed to a shock or liquid or anything - it just died inside the camera body. So glad I checked far enough in advance to replace it. Ordering a different brand this time. 2-3x of usage isn’t worth the $ or the hassle.

works as expected, but have not been able to precisely compare working capacity or longevity to OEM. I can say that charging directly with a USB-C cable and power pack is super convenient and worth a slight loss of capacity, if any.

Works as the original; plus you can recharge it with the USB cable while you recharge the other battery in the camera charger

After 30-40 discharge it doesn't keep charging. Get original spare battery

Makes charging so much easier!

This battery is very good. I like that I can charge it with an USB-C cable.

Remplace parfaitement la batterie originale avec un petit plus non négligeable … la capacité de charger avec un câble usb c

La uso como batería adicional para mi Nikon Z30 desde hace varios meses y me ha funcionado muy bien. Su rendimiento es muy similar al de la batería original; en sesiones continuas de fotografía de poco más de 3 horas ha respondido sin problemas. La primera carga tardó aproximadamente 6 horas, pero las posteriores han sido de alrededor de hora y media. Me gusta especialmente que se pueda cargar directamente por USB-C, sin necesidad de un cargador externo. Hasta ahora, muy buena experiencia. La volvería a comprar.

Rating: 5 out of 5 stars I shoot with a Nikon Z50 and the original EN-EL25 battery is fine, but the charging situation has always been a mild irritation. Nikon's own charger is a bulky brick that takes up a disproportionate amount of space in a bag, and charging via the camera body's micro-USB port is painfully slow. The SmallRig solves both of these problems at once and I am not sure why I waited as long as I did to buy one. The USB-C charging port built directly into the battery is the entire point of this product and it works exactly as described. I charged this from the same GaN charger I use for my laptop and phone, and it was full in under two hours. I have also charged it from a power bank mid-shoot, which is a genuinely liberating capability when you are out for the day and do not want to carry the charger. The Nikon charger now lives in a drawer. Capacity is 1250mAh against the original's 1120mAh, so a marginal improvement on paper and in practice. One reviewer tested this against the original in 4K recording and found the SmallRig ran about 10 per cent longer, which tracks. I cannot feel any meaningful difference in day-to-day shooting, but it certainly does not fall short of the original. The camera reads the battery without any warning or compatibility message, which is not guaranteed with third-party alternatives and was a genuine concern before purchasing. One minor issue worth flagging, confirmed by at least two reviewers including myself: the green LED indicating a full charge does not always illuminate reliably. The indicator goes red during charging, which is fine, but does not consistently switch to green when done. I now charge from a power bank that cuts off automatically when current draw stops, which works neatly around this. One reviewer also notes a fit issue with the Zfc specifically, so Zfc owners should check other sources before committing. On the Z50 there is no such problem. At the discounted price, this is an easy recommendation for any Z50 or Z30 owner.

The battery fits perfectly, connects and supplies electricity correctly. It works well, but I have not yet tested its duration, I hope it is very close to the original.

Per il momento anche se non ancora testata sembra un ottima batteria con ricarica USB c , per la durata aggiornerò poi , la prima cosa ottima è la piena compatibilità con la mia z50ii il che non è affatto scontato con tante batterie non originali!!
