Hey everyone. I recently picked up a Sony A7IV and I am absolutely loving the image quality, but the battery life isn't quite as long as I hoped, especially when I'm shooting 4K video. I have a two-week hiking trip coming up in the Rockies, and I know I'm going to need at least four or five batteries to get through the days where I won't have access to a wall outlet.
When I looked up the official Sony NP-FZ100 batteries, I almost choked at the price. Buying four spares would cost me nearly as much as a decent lens! I've seen brands like Wasabi Power, Neewer, and SmallRig on Amazon for a fraction of the cost, often coming in kits with a dual charger. It’s super tempting to just grab a bunch of those and call it a day.
However, I've heard some horror stories about third-party batteries. Some people say they can swell up and get stuck in the chamber, or worse, cause the camera to overheat or throw an operation not guaranteed warning message on the screen. Since I just dropped a couple of thousand dollars on this body, the last thing I want to do is fry the internals or have a battery leak inside the compartment just to save fifty bucks.
I have a few specific worries:
- Do these off-brand batteries actually hold the charge they claim to, or do they drop off significantly after a few months?
- Has anyone experienced the dreaded swelling issue with brands like Neewer or Wasabi?
- Does using them void the official Sony warranty if something goes wrong?
I really want to be economical here, but not at the expense of my gear's safety. For those of you who have been using Sony Alpha cameras for a while, have you had good luck with any specific third-party brands, or should I just bite the bullet and stick to the expensive Sony originals?

Honestly, I've been shooting Sony mirrorless for about six years now and I've tried every brand under the sun. The fear of frying your camera is mostly overblown, but the annoyance factor is real. With the A7IV, you will almost certainly get that annoying popup saying the battery might not be genuine, and sometimes you lose the percentage display on the screen, which is super frustrating when you're out hiking and need to know how much juice is left. If you're worried about the ultra-cheap Amazon brands, I'd suggest looking at the Watson NP-FZ100 Lithium-Ion Battery Pack (2250mAh). They're sold by reputable photography shops and I've found their capacity stays consistent much longer than the generic ones. If you really want to save, the Wasabi Power Battery for Sony NP-FZ100 (2-Pack) is basically the classic budget choice. I've used them for years and only had one swell after about three years of heavy use. Just keep an eye on them... if they start to feel even slightly tight when you slide them into the slot, toss them immediately. That's the first sign of trouble. As for the warranty, Sony technically wont cover damage caused by a third-party accessory, but it's rare for these to actually fry anything. Still, for a big trip like the Rockies, I'd keep at least two Sony NP-FZ100 Rechargeable Lithium-Ion Battery as your primary ones for the peace of mind and use the others as emergency backups. Better safe than sorry when you're miles from civilization and want your camera to actually work.

I've been using SmallRig NP-FZ100 USB-C Rechargeable Camera Battery for months. They're super convenient with the direct USB port and I havent seen any warning messages on my A7IV yet.

Are you gonna be in direct sun much while hiking? I had a cheap battery swell and get stuck once... Im nervous. Have you thought about using a power bank via USB instead?

I totally agree with the points about physical safety. If a cell expands while you're miles from a trailhead, you are basically stuck with an expensive paperweight. When I'm in the backcountry, I prioritize reliability over saving a few bucks every time. Are you planning on doing long 4K recordings or just short clips? Also, how cold do you expect it to get at night?
