Runpower Replacement Battery for MacBook Pro 13 inch A1278(Mid 2009, Mid 2010, Early 2011, Late 2011, Mid 2012) A1322 [10.95V 6000mAh]

I have had to replace the battery in my MacBook pro a couple of times over the years. This was not a cheap replacement so I was expecting good performance (up time) from the battery however it was really disappointing I just assumed it was normal and put it down to a poor product all be it that it functioned. However after a couple of months the battery would no longer take a charge I contacted the seller and was offered a replacement free of charge. I installed the replacement last night and straight away the performance difference was obvious the laptop ran for several hours on first charge. I have since charged the battery from flat and it has taken over two hours to fully charge much better the original one I was sent. The seller was quick to apologise for the faulty battery and replace was sent out free of charge you can not ask for much more than that. Highly recommend. only reason its not five start is that the original battery was faulty.

I will admit to a degree of apprehension given that there is are lots of cheap clone battery packs available these days and many are either poor performers, dangerous or both. Swayed by not wanting to spend £130 on a genuine Apple pack inc. fitting (latter not needed as I have been working with laptops/notepads for decades) for an older model (still very capable but with available capacity falling below 3000mAh) I decided on this pack and in summary - so far so good.Likes - the pack seemed as well constructed as the original Apple pack (also made in China btw) and although that is no measure of cell or control electronics quality it is a good sign. Equally pleasing was the inclusion of two screwdrivers (one just the right size for the case screws and one less common tri-wing for the battery). The pack dimensions and mounting lug spacing were also good and the pack slipped easily into place. Just 15 minutes and all was fitted and the case closed up. 35% charge in the shipped pack was plenty to boot up the mid-2012 13" Macbook Pro.Dislikes - lack of any instructions. There is plenty of information on the 'net, of course, but this isn't the cheapest of clones and a sheet of basic information would have been good to save an hour trawling though the myriads of web sites to find an authoritative source and especially to remind and guide one that after fitting there is a calibration procedure to be carried out to get the best out of the battery pack.Conclusion - I am quite pleased. Easy fitting, no issues, and after the calibration procedure a very creditable 6172 mAh measured capacity. Of course, long term life cannot be assessed as yet but we shall see. I don't expect quite the number of charge cycles as a premium Apple quality pack but at this price point I am satisfied with that. Remember also - dispose of your old pack responsibly - I'm off to find out where to dispose of mine!

It worked well for about 4 months giving around 4hrs life, but started losing charge thereafter. It never gave anywhere near Apple's claimed life of 7hrs under normal use for OEM batteries, however neither did the original Apple battery. Now, just over a year and ~350 recharge cycles it's down to 4480mah capacity (75% of claimed max capacity). See attached screen grab from MacOS System Report. MacOS tells me to "Service Battery". This seems to be code-phrase for "Your battery is well on the way to being poked". It now lasts about an hour and a half from a full charge for light loads, but intensive CPU and network use will kill it in less than an hour. Disappointing but not immediately catastrophic. You get what you pay for. I'll try a different 3rd party vendor next time to keep poor old mid-2012 MBP limping along.

The battery arrived quickly and was easy to install. The inclusion of the correct screwdrivers made the process much easier. The first full charge with mixed usage gave just over 2.5 hours of battery life. When new my mac would go for over 3, bit considering the cost difference, if you can cope with slightly less battery life as a compromise for half the cost I would say it’s probably worth it. If you need the longer battery life, pay the extra and have first party parts.Can’t comment on longevity yet but as others have said the part does feel like it is made of good materials and does include a warranty.

I have a early 2011 Apple laptop bought in 2016 but the battery stopped charging two weeks ago. I have figured it out, that is very hard to get original new batteries into old laptops. After a bit of research I bought this replacing battery. It came almost fully uncharged (1%) so I wasn’t able to use it straight away, I turned of my laptop and replaced my original to this. I left my Laptop overnight to charge it fully before I turned it on. it looks exactly the same as the original battery. The Plastic feels durable, it doesn’t over heat in use. Fits perfectly in the battery cradle, no gaps, not loose just perfect as the original one.

Battery works a treat and laptop is running cooler and with as good a battery life (or better) than when it was new. No instructions but it is easy enough to find guides online. Only downside reducing this from a 5 to a 4 star review are the two screwdrivers that came supplied with it - if they were the right ones for the job they would have been a very useful addition but neither fits with the corresponding macbook pro. If you are buying this you'll need to make sure you have the right micro screwdrivers available

There is one instruction on the box stating the new battery shall not be fully charged. It would be good if additional information can be provided what is the best approach to extend the battery life.my computer turns off immediately whenever the battery hits ~42%. in other words, the battery works only at its 40% to 100% range. Not as good as the original one.

Fits like an envelope around a cheque, took 10mins no problems, made in China but so seems most of the stuff we buy.
