NinjaBatt Battery A1494 for Apple MacBook Pro Retina 15" [Mid & Late 2013 2014 Years] A1398 ME293 ME294 - High Capacity [11.26V/95Wh]

Quality for installation and use is great so far. Hardest part is removing the old battery. Always take care with doing so.But once that’s done installation took less than 15 mins.

I would not buy this product again. After 17 months and only 70 charge cycles the battery is reporting that it needs changing soon. Having contacted Ninja who merely suggested that it was out of the 12 month warranty and my usage must be excessive to cause this, 2-3 hours per day checking emails and internet browsing/shopping is not what I call high usage.

My MacBook Pro (2014) had been showing no signs of battery failure but the tell-tale that the battery is failing showed up - the trackpad wouldn't click properly.Sure enough when I released the base screws the panel popped up - and as you can see the battery was doing a great balloon impression.Removing the battery on these is always a horrible task. The new one is tricky to align before dropping it in as the sticky pads are very effective; you get one go! I transferred the rubber strips over; the battery reported 85% charge when installed and charged well, runtime seems good so far.The screwdrivers worked well enough and there's nothing to suggest the battery will be any lower quality than the original - I would only buy brand new from Amazon, and not warehouse or marketplace sellers.Good value for a revived Mac but if in doubt ask a professional to install it. Even as a professional I hate doing these almost as much as I hate opening iMacs.

So I was quoted £200 from my IT guy to install a new battery in my ageing Mac Pro, as I was hoping for a new Mac in the near future, I opted for the cheap fix.Firstly take a look on YouTube there are a few videos covering this install. The main issue is getting the old glued in battery out. I found acetone( nail varnish remover) plus a nylon bricklayers line to cut though the glue, worked for me.Popping the new one in was easy, seems to work well, not sure how long it will last, seems to take a charge well.Generally pleased with the overall result.

As described fitted perfectly, worked perfectly.

Easy to install once apple's insanely strong glue holding the original battery in was softened and the bond broken (isopropyl alcohol worked a treat when dribbled under the battery).Unfortunately the new battery did not function as expected and never reached 100% charge, leaving the battery charging all the time (amber indicater on the magsafe charging plug) despite following the instructions to the letter.The seller never bothered to reply to my message which I felt was rather poor customer service. In the end I returned the battery.Thankfully, because it was prime eligible and sent by Amazon, they handled the refund so I was not left out of pocket.

I followed instructions On how to replace the battery on YouTube. I used glue remover spray and sprayed under the original batteries to loosen up the glue. Then, using a thread I worked my way under each battery segment starting from the right side to the left. The whole task took me about 30 mins. I followed the manufacturer’s instructions I discharged and recharged the battery three full cycles, from 100% down to 20%, to obtain maximum capacity. My laptop has now enough charge to play a 5h video in full high resolution and still has some juice left. I find it fair for the price of this battery. It’s like a new laptop again.

I bought one of these to replace the battery in my macbook and i was having trouble where when the computer was under heavy load, and the power usage would go up, it would shut off. This didn't happen with the original battery or when on the power adapter. To resolve this issue, i bought another one. This didn't resolve the issue at all. If anything, the second battery was worse.Something else worth mentioning is that both of the batteries were manufactured in 2015, meaning they had been sat on a shelf for 7 years unused.If you are getting this battery because it is £20 cheaper than the iFixit one, i promise you, spending extra is worth it.

This battery works great - all the supplies to do it come with the unit. The macbook model before this year - the battery pops out so easily. If you need this style of battery get ready to work hard to swap this one out... So much glue you have to rip through! Watch videos on yt on how to not mess it up because it seems like you are breaking stuff while you rip the old battery off the glue.I left the seal on this battery (didn't expose the glue) and just screwed it in place. This is in case I need to replace it in the future - I'm not going to deal with glue again. Good luck! Stop buying mac products.

Arrivata nei tempi indicati e imballata perfettamente.Installazione OK su MacBook Pro Mid 2014 - Mod. A1398 EMC 2876 relativamente semplice a causa della difficoltà nello smontaggio della batteria precedente.Al momento funziona perfettamente. la durata mi sembra regolare, pari all'originale. Ovvio varia in funzione del carico cui sottopongo il PC.

Wat verwacht je van een batterij? Hij geeft stroom en laadt weer op.Dat Apple het moeilijk maakt om een batterij te wisselen kun je nieuwe batterij niet aanrekenen. Past perfect, twee handige passende schroevendraaiers voor 1 maal gebruik erbij, so far so good. Nu kijken hoe lang hij meegaat, de originele heeft het 9 jaar volgehouden voor hij opzwellen.

Einbau in einen alten MacBookPro 15 Zoll Mitte 2014 ging problemlos, Akku wurde sofort erkannt und geladen, Laptop dadurch wieder benutzbar. Es ist eine einfache Möglichkeit das Leben eines MacBookPro zu verlängern. Kurze Warnung! Der Akku ist fest im Gehäuse verklebt, um den alten Akku zu entfernen sollte dieser vorher völlig entladen sein. Die verfügbaren Videos zum Aus- und Einbau bitte vorheransehen. Manipulation an diesen (auch scheinbar ganz entladenen) Akkus kann zu Bränden führen.

I noticed that my 2013 Macbook Pro was starting to rock some when sitting on a flat, hard surface, seemed weird so after a little internet searching, I realized the batteries were starting to swell and distort the casing. My track pad, at least the ability to click it with my thumb, was also not working well. I ordered this replacement battery and received it quickly. There are other similar options out there, but they had additional added things, at additional cost, that I didn't feel I needed. I didn't install it right away, I waited another week or so, but I noticed that my cooling fan seemed to run more often than not, and the case was getting a little more deformed. I made sure I had a current backup performed, then shut all apps down, unplugged, and let the laptop since with the screen active until the batteries completely ran down and it shut itself off. The NijaBatt came with two small torx screwdrivers that matched the 10 case screws on the bottom cover of the laptop, and the two internal screws that hold down the battery connector. These screwdrivers worked fine, BUT they are not very good quality. Make sure you use the right one for each size screw; the case ones used the smaller size, the connector screws used the larger. That said, they look pretty similar in size to the naked eye, so test that they fit right carefully before attempting to remove the screws. You DO NOT want to strip out a screw head. The screws were not in that tight, but make certain you press the screwdriver in firmly as you gently twist them out. There's numerous Youtube videos showing others going through this process. Once the back cover is off, if your laptop is as old as mine, it's probably kinda dusty and gross inside. I used our house vacuum cleaner's hose with a small soft brush attachment to gently move over the internal components and remove most of the dust. NOTE: I DON'T KNOW IF THIS COULD CAUSE A STATIC SPARK, MAYBE, but it did not do so in my case, so no harm done. Perhaps using canned air is a better option...? Anyway, the next step is to unclip the multi pin connector that hooks the battery to the computer board. Only the top flat portion of this connector comes loose, not the entire thing hooked to the board. Mine was pretty tight and took some gentle prying with a non-metallic thingy. Don't try to pry up the whole little rectangular connector box because the bottom 2/3 is soldered in. SO far pretty easy. The hard part comes now. The battery is made of 6 linked sections. They are adhered on the underside to the aluminum case with some very strong sticky tape strips. WHY they need to be SO hard to remove is a mystery; there's not really anywhere for them to slide away into. I suspect it's just another Mac thing they do to discourage user interaction under the hood. According to my Youtube reference, isopropyl alcohol, applied around and between the battery sections will soften the adhesive. Well it did, but not quickly and you still need to pry up on the edges with a stick plastic thingy (some kits come with those) or old credit card, small plastic kitchen utensil. You do this prying slowly, letting the alcohol work in. I cut the outer battery sections loose (wire snips) after I got them up first BUT again, maybe not a great reco since the snips are metal and if your batteries still have some charge, you might make a nasty spark here. Be forewarned. AFter the batteries were finally out, I then use more alcohol to get rid of the left over tape strip residue; using a flat razor to lift the edges a bit then just pulling slowly with fingernails. OK, hardest part done. Try to soak up as much leftover alcohol as you can with little paper towel bits or Qtips. The rest will evaporate soon enough. With you new battery, set it in place WITHOUT removing the plastic adhesive covers. Don't fasten the screws yet, just check for a proper fir and make sure the two screw holes will line up nicely. The take it back out, remove the clear adhesive cover on the bottom and gently put it back in place, trying not to push down on it (and engage the adhesive) until you know the screw holes line up. Press the multi connector back in place, and install the 2 screws. press down on batteries gently to make sure they stick. NOTE the wires going from the battery to the connector have a little U-shaped curve to them. You may need to flex these a bit to make them sit as the old ones did. On my new battery, these wires, seen in the photo underneath the serial number sticker, stuck up a little higher than the originals, but I didn't want to force them down too much and risk damaging them, it did not affect closure of the case. Then remove the top side plastic cover on the batteries; I think this just is used to hold them steady together until installed. I checked that the laptop would them boot up OK, which it did, before shutting down again and closing it all up. The new battery charged up great and has been working flawlessly for about a week now. I do not use it on just battery power that often, so I cannot say just what kind of battery life it provides. The problem of a constant fan running has completely disappeared though and the case is no longer distorted. Dispose of the old batteries in accordance with local regs (public service announcement). As you can see, my old ones were bloated and in eminent danger of doing some serious damage to the laptop and surroundings, I should have done this repair even sooner.
