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

This A2519 battery is a replacement for the factory-fitted battery that comes as standard in a MacBook Pro 14" A2442 year 2021 model. It comes with all the necessary fitting tools, which is extremely helpful. Basic paper instructions are included too, but they're no substitute for watching a tutorial video that shows the entire battery-replacement process happening in real time, with important do's and don'ts mentioned along the way. I recommend watching the appropriate tutorial video online before you embark on replacing any laptop battery. I also recommend wearing an anti-static wristband whenever you're working inside any computer, even if you're only replacing a laptop battery. These wristbands are cheap, they last indefinitely, and they prevent the wearer from frying any computer components with static electricity from his or her skin.My ASMARK A2519 battery is freshly fitted and working well. Most laptop batteries do perform well when they're brand new. The real test of their quality is how well they maintain their efficiency over the course of several hundred charging and discharging cycles. For now, this one is performing perfectly. If its efficiency drops noticeably over the next year or so, I'll amend this review accordingly.The ASMARK battery comes with a 24-month warranty, which says much about the manufacturer's faith in the product. The battery also has multiple built-in protections and has several safety certifications. In short, it's a quality replacement battery.My only criticism is that the battery arrived securely boxed but the box was not sealed. All new batteries should be boxed AND sealed, so that there's no possibility of them being touched or tampered with between leaving the factory and reaching their buyer. That's something this manufacturer should resolve for the future.

This replacement battery comes with all the tools required to replace it into your existing macbook.The engineering here is great, everything looks as good or better than the OEM units and once installed it looks like it is a premium unit.In use it acts just as you would expect, taking a full charge took a couple of hours and discharge is comparable to a new OEM unit, making this an ideal replacement for those that are suffering from quick discharge rates on their macbook.When you take into account the cost of having this done at a service centre, the cost is giving you a great saving and makes this a good value purchase.You should be confident that you can undertake this before purchasing, or know someone that can do it for you as if you buy this and make a mistake installing it, it can become quite costly, so please be aware that this isn't for the first timers of opening a device. Saying that, there are videos online that give advise on how to connect and disconnect them, which is the most problematic part, as it can be easy to damage the connectors if forced wrongly.5 stars for being a good performing unit at a good price.

I had high hopes for this replacement battery, but unfortunately it appears to be faulty. I’ve experienced three sudden drops in charge capacity when the battery level was below 25%, which is extremely frustrating.Even more concerning is the overheating issue. The MacBook is designed to slow down charging after 50% to manage heat, but this battery continues charging at 70W without throttling, causing it to overheat noticeably.Would not recommend based on this experience.

I have fitted many Mac laptop batteries, so I have an advantage where someone that is replacing a battery the first time is going to have issues. After you have managed to open the case by removing the screws and pulling the case off as it is also hooked, the old battery is screwed in as well. It was all quite easy to do but there is a risk of damage even if you are careful. This is a quality battery that performs like the original. The supplied tools fit the hex screws well to open the case. You must be careful not to strip the screw head and keep the screwdriver at an angle to the case as the screws are in at an angle.
