19800mAh Replacement Battery Used for iPhone Xs MAX - 0 Cycle Battery Compatible with Models A1921 A2101 A2102 A2104 with Full Repair Tool Kit

Everything went smooth and noticeable improvement over a high cycle battery. Thanks.

The battery life is not very good, the installation process is quite troublesome, and the functionality is not good. I don't like it.

The specs seem very good, however the materials must be somewhat inferior. The charge does not last as long as my original battery. The phone says 100% but who knows what charge the battery is actually holding? Not me. In my wife’s phone we got a very similar replacement battery and it only lasted 18 months then stopped charging. For the price and specs I took a chance with this one. Hopefully it’ll last for a few years.

This battery is ineffective. Charging doesn't work.

I grabbed this 9800 mAh dual-pack of replacement batteries for our PlayStation 5 controllers because, honestly, I was tired of mid-game battery warning beeps interrupting epic boss fights. These batteries have been an absolute game-changer—no exaggeration. First off, the swap is a breeze. I popped off the old battery cover, swapped them in, and I was back playing in less time than it takes to queue for a match. And that extra capacity? It’s noticeably longer-lasting—sometimes I go days of gaming without ever needing to recharge, even with Bluetooth and lots of haptic feedback. They charge just fine using the console’s USB-C cable, and I haven’t noticed any weird quirks or diminishing performance. It’s like my controllers woke up refreshed and ready for marathon sessions again. Plus, having a spare battery on hand means I can keep playing while the other one charges—no downtime, no panic. If you’re like me and hate getting booted out of a session by a dying battery light, this battery pack is an underrated lifesaver. It’s one of those small upgrades that ends up making your whole gaming experience smoother—and that’s a win in my book.

Why did you pick this product vs others?: These batteries worked well for my PlayStation controllers. I did use the tools that came with them and had no trouble getting them installed. It was nice to have the installation tools included. So far I have had no trouble with them and they seem to stay charged as long as my originals when they were new.

Easy installation battery Complete set good pricing

My ps5 controller battery needed recharging every couple hours. I didn't really look into changing battery until I saw this. My partner helped by changing it out for me, and he didn't think it was hard, but watched a video beforehand just to be sure. So far, playing about an hour each evening for several days and still no need to recharge. My controller worked satisfactorily for my purposes otherwise so it made more sense to change the battery than replace the controller entirely. Fixed my problem without adding any new problems (no overheating, etc) so 5 stars.
