Battery Replacement for MacBook Pro A2442(2021) 14-inch A2519 Battery

I was asked to help to fix a 3 years old 14-inch MacBook Pro (2021 model, with Apple M1 processor), which recently started to show "Service Recommended" warning in the battery status. Apple charges waaaaaaay too much for battery replacement, and sometimes you are really better off just buying a new notebook :). So, I decided to do it myself to save some money and refurbish this MacBook with a brand-new battery. I chose this battery replacement kit because it includes everything you need to do it yourself, with very clear and detailed instructions. The whole process is a bit complicated because Apple never makes it easy for their users to repair their tech. The battery is glued, and you have to disconnect everything and remove the PCB, but once an old, bloated battery was finally removed, putting back this new one was a breeze. It fits right in, has an already pre-applied glue layer and sticks well (wipe out your Mac body inside at the place of the battery with alcohol prior to this) and then put everything back together in reverse order. This 3rd party battery looks just like the OEM one, all connectors fit in nicely, I had absolutely zero issues. As I said, it comes with all the tools you need to replace the battery and even detailed instructions on how to do it, but I strongly recommend watching a few YouTube tutorials first before attempting this repair. I actually needed a few other tools to pry out the old battery, but you still can get it done with what's in the kit. Pro-tip - get a heat gun or a heating pad and gently heat up the area where the old battery is glued, this makes removal much easier. End-to-end, this is a complete kit with an excellent battery, and everything needed to get your Mac back in tip-top shape! And I have saved quite a bit of money doing it myself instead of going to a genius bar. I can't comment about its lifetime, the manufacturer claims it has Japanese cells and all sorts of safety features (overcharge, circuit-overload, short-circuit, temperature protection, and more!), and can be recharged 500+ times, so I'll know in a year or so and will update this review accordingly. So far, my Mac has booted up, and I'm quite happy with the new non-OEM battery, the battery warning message is gone and runtime on a fully charged battery is the same as with the O EM one. No complaints!Bottom line:Yes, definitely get this ASMARK MacBook battery replacement kit if your Mac is telling you to replace the battery and save yourself some good money instead of giving it away to Apple! And the whole process is fun and educational, you'll learn something new. Just be gentle and careful around all cables and connectors inside your Mac.Pros:1. Drop-in 100% compatible replacement.2. Quality seems to be top-notch.3. The kit includes everything you need.4. Fits in place of the OEM battery perfectly.5. Uses Japanese battery cells!6. Has all kinds of safety features.7.

Following the instructions of a youtube video, replacing my battery was easy to accomplish. This kit comes with all the tools you need to replace the battery with ease. This replacement was much needed after owning my mac for years and the battery being depleted. It's just a fact that your Mac will eventually outlive the battery it originally came with making replacing the battery an inevitable part of owning the laptop. Thankfully, I got this replacement and am pleased with the performance of the battery so far.
