    OEM battery, last a long time!

    Verified BuyerReviewed by - September 13, 2020

    [This review was collected as part of a promotion.] Coming from the A7II, I was extremely happy to find out the A7III used a new upgraded battery. So buying this OEM battery as a second has been extremely satisfying. The battery lasts a long time and a massive improvement over the previous versions. You'll be set for all day.

    Don't Cheap Out on Your Power Source

    Verified BuyerReviewed by - January 23, 2026

    [This review was collected as part of a promotion.] Your Review: Stop looking at the third-party "equivalents." They aren't equivalent. I’ve used the cheap knock-offs; they'll show 20% remaining one second and go completely dead the next, or worse, they'll swell and get stuck in your battery compartment. The Sony NP-FZ100 is the industry standard for a reason. Here is why it’s the only option that makes sense: Reliability: The power discharge is linear. When the camera says you have 5% left, you actually have 5% left. No sudden shutdowns in the middle of a shot. Stamina: In real-world use on an A7IV or A7R V, I’m getting well over 600 shots. If you’re shooting video, the heat management is significantly better than the "Wasabi" or "Neewer" alternatives.

    Sony Battery

    Verified BuyerReviewed by - April 8, 2022

    [This review was collected as part of a promotion.] I bought this as a second battery for Sony mirrorless camera. I shoot all day and view pictures and would still have enough juice in it until I get back home to charge it.

    Verified BuyerReviewed by - May 14, 2024

    [This review was collected as part of a promotion.] The battery price is little extra than other brands but worth it and arrived on time. Works great with Sony a7iv and last long as same as an original battery.

    Worth it!

    Verified BuyerReviewed by - February 11, 2023

    [This review was collected as part of a promotion.] You can save money with third-party batteries, but why take the chance....especially when you consider how much you spend on a Sony mirrorless camera body. With genuine Sony batteries, I never worry if my battery will not perform well or that it will possibly damage my camera. Plus I don't have to worry about error messages popping up which I understand can occur when using third-party batteries. The peace of mind for me makes it worth the cost. I bought this as a second battery for my Sony battery grip for all-day shooting at airshows. I prefer buying from Best Buy, knowing it's a genuine Sony product and not a counterfeit.

    OEM over any third party, don’t risk it!

    Verified BuyerReviewed by - September 21, 2025

    [This review was collected as part of a promotion.] OEM battery from Sony, and it’s absolutely worth every penny. In my experience, sticking to genuine Sony batteries means you avoid all the headaches that come with third-party options—no sudden power drop-offs at crucial moments. Sure, it might cost a little more, but the reliability and peace of mind are completely worth it. I’m genuinely so satisfied with how this battery performs, and I’d recommend it to any fellow photographer or videographer.

    Quality over Quantity

    Verified BuyerReviewed by - February 13, 2026

    [This review was collected as part of a promotion.] I have a Sony @C7ii camera, having extra batteries is not enough and especially when they are OEM. Always buy OEM products. Not saying that third parties don't work but they can be faulty (just be careful but they do work) and that will definitely damage you camera that you invested. If you have much the extra money to buy OEM then don't think it twice go ahead and buy it.
