I was worried about changing the battery on my MacBook Air, being that mine is 5 years old. After watching a YouTube video that suggested NinjaBat, I ordered one on Amazon. Just follow the video and it tells you step by step. It also comes with complete instructions. You get the battery and the special screwdrivers needed to change it out. Make sure to keep the screws in the proper place, a few are different sizes and they are very small. So easy! My laptop works great now. No need to buy a new one. I’m very happy with this product.

Old MacBook Pro from mid-2012 whose original battery died. While I've had issues with third-party batteries in the past, this one is working perfectly. It was a thoughtful touch that they included two screwdrivers, especially the Tri-Wing one needed for battery removal. I primarily use this MacBook via SSH, and noticed the system was running slowly without a battery. This is because Mac's power management system deliberately reduces performance when running solely on AC power to protect components from power fluctuations. Since I don't carry the laptop anywhere and it stays plugged in at the corner of my desk, I'm not concerned about battery life - I just needed it to restore full performance. I wrote a script to measure the battery discharge rate, plot is attached. It drained in about 11 hours, drain rate 8.6% /hour

I'm a Macintosh computer consultant, and I've often replaced MacBook Pro and Air batteries for clients. You can't easily find genuine Apple batteries, and when you can, they're outrageously expensive. I've bought many different third-party brands of replacements, and the one that's been most consistently reliable is the Ninja brand. I'm at the point now where it's the brand I look for first when I'm buying.

The MacBook Pro started immediately after installation. That's always a nervous moment. I am using CoconutBattery to check the specifics. It is a Simplo battery, which is one of Apple's genuine suppliers. Full charge capacity is 6600 mAh, the same as my original battery. Battery temperature is fine at 79.4 F. It is indeed a new battery at 0 cycle count. On startup the battery was at 60% capacity. I am beginning the calibration process. The only issue is manufacture date. This battery is more than 8 years old, manufactured on March 30, 2015. That variable seems to be pot luck. I recently ordered a replacement battery for an older MacBook Pro. That was also a Simplo, manufactured in mid 2021. Installation went fine, using a couple of YouTube videos. I recommend the OWC version because it uses the fewest number of steps. Other videos remove items that are not in the way. Also, solvent is not necessary to loosen the old battery. I used a small flathead screwdriver to patiently cut through the paste. There is an opening at right to get started. Once that cell is lifted out of the way it's easy to access the next one. Make sure to totally drain the old battery before beginning. These are dangerous batteries if breeched. I allowed the MacBook Pro to go blank then I restarted more than 10 subsequent times to get closer to absolute zero. Hold down the power button for roughly 10 seconds then release. The Mac will begin the startup procedure. It will steadily cut itself off quicker each time. You're good when the Apple logo no longer appears. I took the extra step of removing the heat sink and replacing the thermal paste, using a video from Luke Miani. However, he errs in spreading the paste on the smaller silver chip at right. That one is not supposed to be covered. I used Arctic MX4 paste instead of the one he recommended.

The battery was exactly as advertised. It fits perfectly and has the rated capacity. We’ve gone from 20 min on an old (original!) 2014 battery to a minimum of 6-7 hours of use from 100% down to 10%. This may grow with several additional cycles from 100 to 10%. The price is very reasonable and it was a nice touch to include the 2 screwdrivers required to do the job. This was a very easy replacement to do. Well done, NinjaBatt!

Very disappointed in battery life. I just use my computer for casual browsing, emails and light use of Word. After following installation and "break in" per instructions I am only getting 2-3 hours of unplugged use. I contacted supplier's customer service who took 3 days to get back to me but indicated 3-5 hours is typical expectation but offered no suggestions or offer of replacement.

Just like it was listed. Works fine so far. Simple to install. Fit as expected.

Replaced an 10 year old in an MacBook Air. Installed in minutes with the provided torx screwdrivers. Follow the instructions for initial start-up and charging cycles. Installed two weeks ago battery performance is as good as new.

Initial review Aug2022 - I was ready to retire my old 2015 macbook but took the plunge and decided to revive it. It was the best choice! After installing this and a new SSD it's working great and ready for a few more rounds. I take good care of my tech but I've never had a laptop last this long and still so fit for work. The old battery was swollen and in need of urgent replacement and this one fit perfectly. Taking the old battery out was hard work (YouTube can help with that) but installing this one was a breeze. The instructions were very clear and straightforward. It works perfectly and lasts much longer than the old one. Couldn't be happier! Update Apr2023 - battery worked well but lost most capacity after 6 months.

I put this into a Macbook Pro 13" 2017 (A1708) for my daughter. The original Apple battery was reported to need servicing. It is always a chore to remove the old battery as it is well stuck on the chassis. The battery does *NOT* come with a ribbon cable for the battery daughter board to the main logic board so do take care in keeping the original cable. Installation went well. Battery only had 5% charge so needed to run a full charge cycle. Coconut battery app reported the battery to be manufactured in April 2022. This is not too bad as I have had batteries from other companies sitting on a shelf for years. I can't say how this will perform as only time will tell. Some replacements I managed to eek out years while others only under a year.

One of the screwdrivers doesn't fit, and I haven't been able to change the battery yet. Please help!

Facile da montare (ci sono bizzeffe di tutorial su youtube) e, al momento (dopo quasi un anno), regge bene la carica

Batterie installée avec les instructions fournies et l'aide de YouTube dans un A1502. Les outils sont fournis. 103% health! A voir la durée dans le temps mais mes expériences précédentes ont toujours ete positives.
