Apple picker Sooner or later it will happen to every owner of an apple laptop. The ever-shortening battery life inevitably leads to the crossed-out battery icon in the top bar. If you're only running on an external power supply, alas, how someone will trip over your cord. MagSafe does prevent damage to the connector, but all the hard work is gone at that moment and the health of the disk structure is not good either.
Changing the battery is a must in this situation. If it weren't for Apple's restrictions, it would be a trivial matter of a few minutes - it took a few days to replace the battery on a 2010 1321-inch MacBook Pro. The first thing is to find out the type and model of the battery. After unscrewing the aluminum bottom cover, the marking AXNUMX can be confirmed.
What battery?
More expensive, original and cheaper, non-original batteries with a slightly shorter lifespan are sold. On amazon.de, which sends to us quite promptly, you can get the original for 119 euros (3 crowns), the non-original for 100 euros (59 crowns). Our two spare parts dealers, MacZone or MacWell, will sell you this battery as long as you have the ID number, there are others who don't care. Uncle Google will tell you.
Unibody MacBook Pro after opening the aluminum bottom cover. The battery is held on the side near the edge by three aluminum clamps, on the other side by three triangular screws. The connector can only be pulled out after lifting the battery.Screwdriver
You bring the battery, loosen the screws holding the back cover with a watchmaker's Phillips screwdriver (like Narex 8891-00). You want to continue with the other three screws that hold the battery. But hey, you're face to face with Apple's deliberate compensation for the friendliness of its software.
Plastic strap to lift the battery and Apple's swag: Triangle, star...
These screws have a triangular groove and you cannot loosen them with anything other than a special screwdriver. Finally, after a few days of searching, I was successful at GM Electronics. The triangular screwdriver Pro'sKit 9400-TR1 for CZK 45 is exactly the right one.
Exchange
Then it went from time to time. Three screws gone, lift the battery by the plastic strap, push the connector into the space below it and the battery is out.
The raised battery makes room for the connector to slide out
Remove the three protective films from the new flashlight from iPower, insert the edge under the three aluminum pawls, hold the battery by the pay band, insert the connector of the new flashlight under it, place it, screw it in, and voila!
Red light shows: MacBook Pro is charging
Pressing the button on the side of the machine: We already have the first dash.
The power supply is recharging, the flashlight flashes the first LED. By the time I finished writing this article, I had 100 percent.
I really don't understand why Apple makes these screws on purpose. Triangles, six-pointed stars, pentagons, these all hold exactly the same as a classic cross, don't they?
I'm probably due for a replacement soon. I have an MBP early 2011 and after 81 cycles the battery level is 31% :/ I would rather recommend a dealer with "higher quality" non-origo batteries. I'm thinking of giving them a chance as the Apple battery lasted less than the battery in the Dell I had before the Macbook. And paying 2-2.5 times more... is it worth it?
What did you do with it? :D I also have an early 2011, 15″, 2,2 GHz, the battery has more than 500 cycles (of course, not all of them are full 10% > 100%) and it still holds up quite well – when surfing the net, documents, etc. easily 3-4 clock. True, I only use the laptop at home and I have never let it discharge to 0%. But I would definitely not go for anything other than the original battery.
It's a mystery. The laptop is mainly used at home connected to the network. I maintained the battery once every two months (according to apple instructions) and used it without an adapter about every three weeks... I must have received the wrong part. However, the most interesting part was that I had 76% until about 82 cycles and then it suddenly dropped to 31% and in the system profile it says that the battery needs to be replaced :/
I also have a why early 2011 and I'm a little different :-D
Number of cycles: 1146
Condition: Needs to be replaced soon
Have you calibrated the flashlight once in a while? If not, the life of the battery decreases much faster without calibration.
Where did you order the screwdriver, a link would be great, thanks

Thanks, I got it :)
Thanks :)

I have a macbook pro 13" (2009) and after returning from a long stay in the hospital, the flashlight says:
Number of cycles: 389
Status: Submit the battery for repair.
It's been almost 1/2 year, but the battery still works... on the mains and some of that without a mains (I didn't measure). Does anyone have a similar experience?
Well, without the network, it's not even close to the original value. That's why he writes it, I had an experience with it a few years ago too.
some time it was supposed to be an hour, two, three... I didn't measure it, so it's hard to say
clear! Macbook pro 2008 and it has been telling me the same thing for two years. The battery lasts about half an hour, but that bothers me less than giving a three for a new one. Take it easy :D
I was wondering how much it would cost. About 5000 in the Czech service and exchange, which is no longer worth it to me :-(
I have to brag :-D I have a macbook pro 15 2011 late :-) bought last year in October :-) so it will be a year since I have it and I have 6911 Mah from the factory 6900 :-D when I unpacked it I had 7000 mah but that's not the production capacity :-D 85 cycles :-) I regularly do one of those cycles once a month :-) but I still carry it somewhere and since I've been riding mavericks, my endurance has brutally increased :-) by almost 1,5 ,2-XNUMX hours :-):-D
I guess I'm still fine... MacBook Pro 15″, Mid 2010, battery 86,7%, 2,8 years old...
