Used Green Extreme NP-FW50 Lithium-Ion Rechargeable Battery Pack (1030mAh, 7.4volts)

2025-05-19T15:06:04

The charger seems fine, so far. Bought extra charger plates for Sony NP-BX1 batteries for my HX99 and I like that I can charge one of each if necessary. The problem is the batteries. Bought them for my Sony RX10IV. The batteries are just slightly too large. I can put them in but it's a friction fit, and it's hard to get them out. Will be buying Sony batteries and keeping these for emergencies.

Battery started to swell in size after having it for only a few months (and having charged it maybe 20-30 times). Now I can't use it in my ZVe10, as it's very difficult to take out of the battery cavity (for some reason, my a6400 is a little easier with this battery, but something is still not right, as it shouldn't be difficult at all - and the Sony batteries do not have this problem. Charging plate also failed (separate review) after same amount of time.

Exactly what I needed. And nothing particularly special about it. It charges quickly, has a bright display to gauge charging status. But this review is less about the product and more about Adorama customer service. I received the wrong battery type and without missing a beat, customer service sent me another one quickly and helpfully communicated along the way. Very grateful. Thank you adorama.

Great product. I used it to video a high school football game from a crows nest and the battery kept its charge and then some. Worth the value!

Batteries are great charger not so much. It?s hard to get a connection to the battery. But for the the price I?m happy. Batteries last about 80% compared to original Sony.

I bought this because my 4-5 year old batteries are showing their age: batteries drain faster and are weak in even moderately cold temperatures. This battery, despite being new, doesn't perform any better-I won't buy another.

I got this as opposed to other off-brands because of the advertised "boost" feature which supposedly revives batteries that won't even begin to charge. Didn't work for me, though maybe there was something else wrong with that particular battery. Anyway, happy otherwise. Interchangeable plates are a plus. Batteries themselves seem to provide as much juice as Sony. And it's nice that it includes a power plug as opposed to just a USB cable.

They arrived about 47% charged, the charger had a window that showed how much charge was on the battery. I thought that was a very nice idea,As it can be used to check a battery before an outing to see how much power is left.

These batteries last nearly as long as the Sony batteries for half the price. Unfortunately, mine swelled in size and was not only able to fit into the battery slot any longer. It was still in the warranty period though and Adorama replaced it quickly without any hesitation. Great customer service!

These batteries lasted five months. They will not charge. Get the regular Sony batteries. Spend the extra money as you will replace these anyway.

Well designed and thought-out. Works great. Nice to have a solid battery system for my Sony a7Rii.

Although I have had the battery about 3 years - I only used it maybe 5 times. It never held a charge. I would charge it and put it in the case and then need it about 2 months later and it is dead. Finally went to charge it again yesterday (after it died in the bag), and it will not charge. The Green Extreme charger flat-out refuses to charge it and the Sony charger will get it up to about 80% and then the battery just keeps resetting - never accepting a full charge. It is going in the garbage. I guess I will stick with the Sony OEM batteries.

Took a chance on a brand I have never used before. So far the batteries are as good as the more expensive ones.
