Wasabi PowerNP-FW50 Camera Battery (2-Pack) for Sony ZV-E10, Alpha a5100, a6000, a6300, a6400, a6500, Alpha a7, a7 II, a7R, a7R II, a7S, a7S II, Cyber-Shot DSC-RX10 II, RX10 III, RX10 IV and More

These work perfectly with my Sony a6000.

Wasabi batteries for my Sony a6000 works very well for about $15.00 compadres to Sony for $58.00 or Watson for $25.00. Wasabi hold charge very well and are still working after more than a year of use.

UPDATEDI was upset with the batteries failed initially and rated the product 1 star. As I was looking for replacement batteries, I decided to look at Wasabi's warranty as to 6 months or 12 months. I was surprised that it was 36 months. I contacted Wasabi per their warranty instructions. In less than 48 hours, I received a note apologizing for the inconvenience and informing me that the replacements were shipped. I received the replacement batteries in 2 days. I am very impressed by Wasabi standing behind their products, and, the excellent, prompt, and no hassle warranty service. I would give them a 5 star for their customer service and standing behind their products. But since the first set of battery failed. They will get a 4 star rating and I will not hesitate to buy Wasabi batteries again.THIS WAS MY INITIAL REVIEWI have these batteries for just one year. At the end of owning it for about 10 months, one of them has lost its maximum capacity to about 50-60% as it was indicated in my camera. At the end of one year, it stopped charging using the charger came with the package. This battery was one of the 5 batteries I have and used and kept fully charged regularly. I have batteries that have been used for the past 8 years and still going strong. The Wasabi was a disappointment!!!

Purchased 4 (2 sets of 2). Used at two brief events over a few months. All were charged twice. Inserted for a third outing to test, and one of the 4 became swollen and stuck inside of my camera, requiring a pry with pliers to remove it. Then immediately after that, 2 of the batteries no long hold a charge and do not function. I am fearful to put the fourth remaining battery in my camera. Now I have two chargers, and batteries that are useless. Hoping I can figure out how to seek support from the manufacturer.

I have reliably used Wasabi batteries in Nikon and Sony cameras for about 10 years. I purchased two NP-FW50 for Sony A6000 in early 2023. After just a few months, neither of these new batteries would hold a charge. I contacted Wasabi by email per their website and received two replacement batteries in less than one week. They'll keep me as a customer.

They work well so far!

These batteries are good for backup, but the reported percentage of charge is inconsistent. Sometimes the charge can range from 20% to 60% based on temperature and usage within a couple minutes. So It's best to make sure all of them are fully charged, before doing a photoshoot or going on a trip.

in the past I ordered 4 Wasabi batteries 2 for each of my cameras. The have good battery life and longevity. This last order, I didn't even think to check the batteries and two months later when I went to use them, they would not hold a charge. I contacted Wasabi directly and they immediately sent me 2 new batteries. They are charged and ready to go.I will continue to use Wasabi batteries. The battery and the customer service is excellent.
