NinjaBatt Battery A1278 A1322 for Apple MacBook Pro 13" [2009 2010 2011 2012 Years] - Long Lasting [63.5Wh/10.95v]

I've used this battery for over a month now and couldn't be more pleased. I've gotten as many as six hours combined internet and general work, word processing and spreadsheets, out of this battery. Obviously your mileage may vary, but this battery performs far better than inexpensive eBay batteries. Yes, it's around twice the price of the cheapies, but way less expensive than Apple OEM batteries. It comes with everything you need to install it. (I'll follow up on this review next year to see how it's performing then)

After only 9 months and 144 cycles the battery has fallen to 70.1% health, or 4044 mAh of capacity. Attempts to contact NinjaBatt by their "contact us" website form were not answered, and when I called the telephone number, I was greeted with a standard greeting, then their system hung up on me. Four times.Update: I did eventually manage to contact them by telephone, and the rep agreed to send me a replacement battery. The rep seemed to recognize who I was right away, because apparently they had taken note of my many attempts to contact them by a variety of other channels before we spoke.

I used this battery as a replacement for an Apple original battery on an old 2011 13 inch Apple Macbook Pro that was no longer able to hold its charge. Along with replacing the battery I also upgraded the Macbook Pro's spinning media drive (HDD) with a solid state SSD drive from Crucial. Both installation were straightforward. Installing the SSD meant I had to reinstall the operating system. Since making the upgrade and over the last month I have had been using the battery I have noticed a dramatic drop in battery performance. The original working Apple battery could hold a charge for at 5 - 6 hours of use. The Ninjabatt was able to hold it for three hours when I first got it. And after a month's use it is down to just 90 minutes. The laptop is used to for simple web based applications - Gmail, we browsing. I will need to find another battery for my Mac. Not sure if it was defective battery or not - I only purchased the single battery. Since its been five weeks from purchase I can no longer return it. Will need to look for another.

Updated Review (August 2020): The battery worked fine for a few months, then suddenly would not hold a charge (i.e. 0%). Tried a brand-new charger, but same results. Computer runs while charger is connected, but immediately dies when unplugged; battery remains at 0% at all times.Original Review (April 2020): The battery case's dimensions were exactly the same as the original Apple battery. Ran it completely down overnight (virus scans, etc., to tax the system), then did a full charge the next day. Ran 8-10 hours per day under heavy use while working from home.

Great replacement battery! My old Macbook Pro (2010) came back to life!It came well packaged, and included 2 screw drivers needed. It was fairly easy and quick to replace the battery. I wore disposable gloves on and made sure the table surface was clean, to avoid any moisture and dust. After replacement, plugged the laptop to the power outlet, and it worked immediately. The new battery already had about 85%. No date or time change were needed.

I ordered this battery. It was super easy to install, and I have installed a number of batteries on other machines before. Except it would not charge and the computer would not recognize that it even had a battery anymore. So, NinjaBatt told me to have Amazon replace the battery. Meaning I have to return the previous one, wait for the next one to come, and then install the next one.I did install the second one. I emailed customer service asking if I did anything wrong. They gave me the same instructions that don’t make sense or work with the issue I had explained to them I was having. Then they offered me another battery. A THIRD. There’s NO WAY that I got two defective batteries in a row if this is a reputable company. They won’t work through any issues, just want Amazon to replace it. I would not ever recommend this company or this battery. Now my computer hasn’t been functional without being plugged in for a week and I also have the hassle of returning two batteries.

Although this battery costs a few more bucks than others, it is worth it. After installing, I suggest using the laptop until the battery is below 10%, then give it a full charge. Repeat once more. Then you will have a great battery that charges up to what it is advertised to do. This is an easy battery to install. Be delicate when pulling the battery connector loose. And I think you will be very happy. Don't expect any fast reply from the manufacturer if you have question's. They are either very slow or simply ignoring tech support requests. Nothing annoys me more than poor tech support. If the pandemic doesn't allow enough staff to support the product, stop selling it until you are willing to put in the effort to answer email requests. If you are staffed well enough to sell and ship the product then you are able to answer email questions. GREAT BATTERY though!

Can't really say too much about the battery as it's so new, but the look and feel was much higher quality than the RayBom (or whatever it's called) that I bought not much more than a year ago. It expanded and looked ready to explode. The original battery never did that, it just stopped holding power. This battery was easy to install and came with the needed screw drivers, which I'm keeping this time. Do wish it had come with screws as the screw I had for the battery seems to have disappeared, probably after I replaced the keypad.

La duración de la batería en mi MacBook Pro 13' mid-2012 usando Windows ha sido bastante decepcionante. La batería original, que tenía 9 años de uso, se hinchó y presionaba el trackpad volviéndolo inutilizable, razón por la cual la cambié por esta de NinjaBatt. Pues bien, la batería original, incluso en ese deplorable estado, me daba 1h50m de uso ligero, frente a las 4h de uso que me daba cuando estaba nueva. La batería nueva de NinjaBatt me da únicamente 2h50m de uso, muchísimo menos que la original cuando estaba nueva. Además, incluso después de un par de ciclos, la indicación de porcentaje de batería restante es poco fiable. Normalmente cuando el indicador llega sobre el 25%, cae abruptamente a sobre el 7%, así que no te puedes fiar en condiciones de carga baja. Esto nunca me ha pasado con una batería original y da bastante mala sensación.Ahora bien, Apple ya no instala ni distribuye baterías originales para este modelo, así que las alternativas las desconozco, pero sí sé que en tiendas te cobran 120€ por cambiarte la batería, y esta me ha costado 60€ y se instala fácilmente en 10 minutos. He decidido no devolverla y quedármela, pero si lees esta review, no hagas mucho caso de la demasiado buena valoración que tiene en Amazon, es una batería normalita. Si la compras con esas expectativas, puede seguir siendo una buena compra. Veremos si aguanta bien los próximos meses. Si algo falla, actualizaré mi opinión.Actualización tras un mes y medio de uso: la batería ha decidido dejar de cargar, se ha descargado del todo, y solo tras estar jugando con ella conectando y desconectando el cable de corriente varias veces, ha decidido aleatoriamente volver a ponerse a cargar. Mala pinta, bajo de 4 estrellas a 2 estrellas.Actualización tras tres meses de uso: El vendedor manda spam amenazante continuamente por email exigiendo que cambies valoraciones negativas de Amazon. Por tanto, bajo de 2 estrellas a 1 estrella.

Mi sembra doveroso fare una bella recensione per questa batteria dal nome buffo ma dalle ottime caratteristiche.Il mio MacBook pro early 2011 a distanza di 9 anni è ancora oggi un ottimo laptop.Cambiare la batteria è davvero un gioco da ragazzi. Mentre la sostituite vi suggerisco di smontare e pulire la ventola.La mia era quasi completamente intasata e questo causava un eccessivo surriscaldamento della CPU. Il famoso sito iFixIt spiega passo passo come fare.Mentre avevo il Mac aperto ho anche smontato tutta la scheda madre ed ho sostituito la pasta termica che sta sopra la CPU. La procedura non è proprio semplicissima ma con un po' di manualità ci si riesce. La pasta termica dopo 9 anni è tutta secca e non assolve piu' al suo scopo, pertanto la sua sostituizione è altamente consigliata.Se ancora non lo avete fatto sostituite l'HD con un SSD e portate la ram a 8gb.Dopo aver montato la batteria è molto importante calibrare il sistema di power management. Per farlo bisogna eseguire queste seemplici passi.1. A computer spento caricare la batteria al 100% fino a che la luce non diventa verde2. Scollegare il carica batteria, accendere il computer, disattivare le funzioni di risparmi energia con alimentazione a batteria e far scaricare completamente il mac.3. A questo punto ricaricatelo completamente ed usatelo come fatelo normalmente.

Update Oct 2021.It has stopped working. I had the egoway before which also didn't work properly. I think all these replacement batteries are simply not up to a good standard. This worked ok for a while but started losing charge after a few month and now charges fully but depletes in half an hour. Mac has flagged up 'battery weakness'.If you need one for a few months it will get you by. But simply, most of these replacement batteries for Mac's are rubbish .I have a MacBook Pro mid 2011 (i5 2.3GHz) and I purchased a replacement battery as mine did the internal imploding/expanding thing and Im lucky the Mac survived it!!Searched extensively on line and decided to buy a replacement battery which was actually Amazons 'choice' but not an Apple product (they do not make batteries for this Mac anymore I think). The battery had amazing reviews and said 7hrs blah blah blah. Ordered, installed and it was around 2/3 hrs after a full charge, on half dimness and just using the net. Any video/streaming and it depleted super fast! In the end, I tried to write to customer service of the company that made it (they were based in China) but got no reply. Contacted Amazon customer service who kindly gave me a refund, even though I was out of the 30 day return. Have to give them Kudos for that as they were pretty good.I bought this as a replacement battery before I even got my refund as the reviews seemed good - even though there are not so many reviews for it. When it arrived, it was a different thing altogether. Really well packaged and lots of instructions. Even telling you not to calibrate it by deleting the first charge to zero but to 20%. Within the first charge it was noticeably different from my other purchase. I put the timer on (like I did with the other battery) and on first charge it lasted over 4 hrs to 20%. A MASSIVE difference to my last purchase.Basically, anyone reading this review and after a battery for an old MacBook who's battery has give up the ghost. Get this. It might not be as amazing as the old Mac batteries but its pretty damn close. Its also a quality product and came very well packaged. I highly recommend it and hope as time goes on the charge holds even better.Straight up great replacement for an old Macbook battery

Comme mon MacBook Pro est plus souvent utilisé relié au secteur et rarement sur batterie, c'est le "syndrome" du dysfonctionnement du clic du trackpad qui m'a fait comprendre qu'il était plus que temps de changer la batterie d'origine (batterie gonflée et risque d'incendie possible).En effet si vous constatez que le clic de votre trackpad ne fonctionne plus, il y a de fortes chances que ce soit lié à un problème de batterie qui en gonflant finit par bloquer ce dernier.J'ai donc sélectionné et commandé cette batterie.Lors de la procédure de changement, j'ai pu comparer les deux batteries et effectivement la batterie d'origine était vraiment bien "gonflée", il était plus que temps de changer !L'installation de la nouvelle batterie s'est très bien déroulée sans aucun problème particulier, d'autant plus que les tournevis adéquats sont livrés avec et semblent de bonne qualité (je les ai ajoutés à mon kit iFixit pour certaines vis plus en "profondeur", notamment pour le démontage d'un Mac Mini) !Après remontage, la batterie est fonctionnelle sans aucune manipulation supplémentaire, et le clic du trackpad est revenu.Aujourd'hui, cela fait presque un mois que j'ai installé cette batterie, elle se charge bien à 100 % et aucun problème particulier, d'autant plus que mon MacBook Pro reste allumé 7/7j et 24/24h.

Some facts I have got here.* It comes with an 80% battery for the age of 142days, which is pretty good.* 80% battery lasted for about 4 hours with just minimum playing youtube videos in the browser.* Full charged capacity 5977mAh > designed capacity 5700mAh* First overnight charge went well
