NinjaBatt Battery Replacement A1502 A1582 for Apple MacBook Pro Retina 13” A1493 [Early 2015, Mid 2014, Late 2013] - High Performance

Perfect replacement for my 2015 13" MacBook pro. These batteries don't last all day in the older Mac laptops because Intel CPU's are not as efficient, but this one will last about 6 hours of random surfing, typing, or other non intensive tasks, but if you are streaming on YouTube, Netflix, Paramount+, etc. the battery only lasts about 4 hours. For these machines, that was pretty good back in the day. Functions perfectly, and was easy to install once the old battery was removed. Instruction manual could be a little more detailed, it looks like it was translated from another language (possibly Mandarin Chinese or Japanese) but you likely won't need it if you are skilled enough to take out a MacBook battery and replace it. A huge factor for me to buy this one over the others is that there is a 1 year warranty on this battery whereas other batteries on Amazon do not have a warranty.

Update: I purchased May 2025. It is now March 2026. The battery life is still intact. Best DIY ever!! It works!! The installation went smoothly. I followed a video I found on YouTube and found it pretty easy to replace. My OG battery wasn’t charging and I couldn’t even use my laptop while plugged in or it would die on me. Apple wanted to charge me $300 for the battery replacement. I decided to purchase this battery due to the mostly good reviews I read. This was my first time changing a battery on a device. When I was done, the laptop wasn’t turning on and I thought it wasn’t going to work (disappointing!). However, I left it to charge for a little bit and within 20min or so the laptop turned on and battery was on 50%. It has been three days since I replaced it and I have not experienced any issues so far.

After looking at some YouTube videos I got this one. So happy that it worked and is holding a charge..

I recently purchased the NinjaBatt replacement battery for my Macbook Pro, and the entire experience has been nothing short of a nightmare. I ordered this battery as a replacement for my swollen Macbook Pro battery, hoping for a seamless upgrade. However, the NinjaBatt has turned out to be a complete disappointment. Firstly, the installation process was the only positive aspect, as the battery shape exactly matched the original OEM battery, fitting well into place. Unfortunately, any glimmer of hope was swiftly crushed when I realized the battery was completely discharged upon arrival. Despite a seemingly straightforward charging process, my Macbook could only charge this battery to a mere 39% after a staggering 5 hours of charging. Even more concerning, the battery's charge dissipated at an alarming rate after unplugging the power source, far quicker than my original 9-year-old OEM battery. On the second charging cycle, the battery's performance further deteriorated, and I could only achieve a laughable 27% charge. It's abundantly clear that this battery is not only defective but also boasts a significantly smaller capacity than the original OEM battery. This experience has left me questioning the legitimacy of NinjaBatt's products. Whether it's a blatant scam or a result of abysmal quality control, I am utterly disappointed and frustrated. I strongly advise against wasting your money on this product. Save yourself the trouble and opt for a more reliable battery from a reputable source. I am beyond frustrated with this purchase, and to add insult to injury, attempting to return this defective battery is an absolute nightmare. The battery is glued to the case, making the return process an arduous and messy ordeal. Save yourself the headache and steer clear of this subpar product and its infuriating return process.

Updated review: NinjaBatt sent me a new battery after searching and finally being able to contact them. They were nice about it and just sent a new one out. It arrived actually really fast, only a couple days I think. New battery is installed and working good. It arrived with 40% charge. I'll follow the included instruction to run it down to 10% then charge to 100% and repeat this process five times to make sure it has full capacity. This is on my wife's laptop, so I'll also move all the files and folders she has on the desktop to the documents folder to save resources from the computer. Thanks NinjaBatt for standing behind your warranty and making the process easier. I moved the 1-star review to 4-star because of this, but I can't go to 5-star because the first battery did fail, and my expectations are lower now. Old review: I bought this with high expectations for an aftermarket battery. Installation went easy and battery held a charge right away. It didn't seem to be a high quality battery as the total charge held was similar to the old original Apple battery that I was replacing. Well, after 7 months, the battery now won't even take a charge. It won't charge past 1% and it says it has 23 cycles under it and needs replacement. What do you expect with a Chinese product. Trash.

Der Akku tat, was er soll, er ersetzte den in meinem alten MacBook Pro Late 2013. Der Einbau war wesentlich einfacher als befürchtet oder bei den Nachfolgemodellen (dort würde ich es nicht mehr selber machen). Wichtiger Tipp beim Einbau: Erdungs-Armband (Draht zur Heizung o.ä. zur Erdung) verwenden.

Excelente batería. Mi Macbook Air del 2017 que iba fatal y ya lo iba a tirar y a comprar uno nuevo volvió a la vida. Va tan rápido como el primer día. Esta batería aparte de devolverle toda su funcionalidad al ordenador, dura muchísimo. Cuesta un poco más que otras pero no me arrepiento de la compra. Llevo un mes usándola y estoy muy satisfecho. Luego la instalación ha sido muy fácil.

De momento funciona bien. El Mac la detecta como batería original. El sensor de temperatura funciona correctamente. No viene tan equipada, no trae cintas doble cara para pegar la faja del trackpad ni el regulador de carga pero si trae las herramientas necesarias y guantes.

La rapidez de su entrega de lo demas Todavía no puedo decir sólo que hasta ahora muy bien

It's too soon to tell, but it seems to be working well thus far. Battery arrived at 42% charged, discharged to 20% slowly, then dropped fast. Am charging it for the first time now. The first shipment was horrible, incorrect box, wrong literature, no screw drivers - an absolute disaster. But they were quick to ask I return it for full refund. So I took a chance and re-ordered another one. Arrived the next day, all as described and properly boxed. I am in the process of returning the first one now. While I can't explain why the first shipment was so bad, they have fixed the issue quickly. Time will tell how good the battery is, as I can't tell the date of manufacture, but it seems ok for now. If I do not do an update then all is well.
