- Extend the life and charge capacity of your Mac laptop battery by calibrating the power management system.
Read the 7-step guide here:
www.newertech....
While NewerTech Batteries Are Shipped Up To 30% Pre-Charged...
It's absolutely essential to calibrate the power management system after installing any new battery from NewerTech or any other top brand. The power calibration process syncs the computer’s power management system with the battery which allows:
- Your new battery to achieve its fullest charge capacity.
- Your new battery to reach its full lifespan.
- The system to accurately display the battery level.
I also turned my screensaver off and set the screen and keyboard light brightness to high to drain the battery faster.
It's not a very diffcult process, but it's rather very lengthy.
Good video. I suggest for future you reduce or completely eliminate the background music, its annoying and unnecessary.
There are a few things for battery repairing
Don't attempt to do this unless you are sure what you are doing - the acid can burn your skin
Test the voltage first - there may be a kaput cell which will waste your time.
Check your battery fluid.
Try to completely recharge the battery.
(I discovered about these and more using rapid renew roadmap site )
I like the music it reminds me of my fathers iMovie videos he made of our family. He fell off a cliff will miss him
@@zlatanmustacevic9261 You have no idea what you are talking about and should not be allowed onto internets. Literally nothing you wrote is true.
Li-ion laptop batteries do not have liquid acid, or any liquid at all for that matter. Testing voltage will not give you any information about the internal cells, nor are they user-serviceable in Li-ion laptop batteries.
Again, there is no fluid to check.
Got mine replaced, recharged it after it died (when it turned on it said 50%) then I charged it to 100 so I used it til it died (I don’t count that cycle) so then what I did was I charged it up again, switched the settings. Now I use it til it dies and then wait the 5 hours again, charge up and THEN SMC. Should read the correct settings afterwards. Nice big 8600 MaH battery cell.
RESET the SMC, as well. This is a very important step that this video is missing. After doing all of what this video says to do your battery is NOT fully calibrated. I guess technically the battery is, but the MacBook still has to adapt to the new battery. So reset the SMC!!!
What is SMC?
Do you reset it after doing all these steps?
SMC is the System Management Controller that governs a lot of the hardware and electronic components of our Macs. The process to reset SMC differs across different types & generations of Macs, so if you are interested, search Apple Support or Google for your Mac model and the phrase "SMC reset" for guides & instructions.
I've read that the reset should only be done in certain situations.
@@Black-Circle apple are idiots and i hat them all BUT i think they wont be that bitchy. Maby you bought a battary with a smaler capacity
I think this worked for me. The "service battery" warning went away. :)
Update, the battery service alert is back. Gonna just buy a new one.
Update again, the battery that came with the Mac was inflamed badly. The cells were almost ready to burst. Go change your Mac batteries lol.
Another update. The original battery was bad, real bad. Most of the battery cells were inflamed and swollen. Lol. Take urs to an expert !
What bugs me, is reinstalling the OS, also makes it go away lol .. I eventually replaced the battery as the Power and "current" charge in System report didn't match when fully charged.
FYI.. Thats also a good indication as you cannot rely on "service battery" warning..I quickly got used to that,.
@@picvic7 this time, what battery did you buy, and is the "service recommended" warning still there?
My battery is new but it stills says “service battery” will this fix it
did you fix the Service recommended warning?
Hi there, thanks for the informative video. I did the battery calibration as per shown on the video, my battery goes from "Normal" to "Service Battery" even though it was working fine 76% capacity and 657 cycle count according to System Information. Could you please inform me on how to resolve this now? Thanks
This is for NEW batteries you just installed.
Your MacBook could use a new battery
@@sghantous I just replaced it with iFixIt one...
my friend, batteries are inexpensive now. about 40-50 dollars for brand new battery. You got incredible use out of your last battery (almost 700 cycles).
I would buy a new battery and install it myself. Be well.
Thank you. The explanation is very clear, spotless, concise and easy to understand for me.
it's a cmputerized voice, it should be easy to understand :)
The newer tech batteries are very very good, with long long life. Just got mine in mail from OWC :)
If you just got it how can you say it has a long life lol
Does this work for any off brand battery? The battery replacement I got had different instructions
Can I just leave the MacBook discharging in sleep mode? albeit a much longer discharge. I feel uncomfortable leaving it with the screen on for so many hours.
it is ok to have the screen on for five hours. it is only damaged if it it is left for a long time. Apple knows this and that is why they ask you to do the calibration. It is safe.
I just put in a new battery on my MacBook Pro but the battery never fully charges. The highest battery percentage thus far is 96%. Even after hours of being plugged in, the percentage does not change. What can be the issue?
MacSales. com I did not buy the battery from macsales but I figured the troubleshooting processes would be the same
MacSales. com I've done both and will now let my mac charge. If nothing changes I will definitely get in contact with the seller and work something out. Thank you for your helpful information
So, what is this "SMC" step that we are supposed to reset (that Evil Master) talks about in the comments below? And, like he said, is it the last process we do?
You do it at the end. Sometime the battery status bar and the real battery capacity will not show the same numbers (in other case when the computer is plugged in it's not showing that it is recharging and when it's unplug it shows that the battery is still charging).
1. Turn the computer off
2. Hold Shift + Option + Command + Power for 10 seconds then let go of all the buttons &;
3. Press the Power button to start the system.
Your SMC should be reset now!
Good luck!
@@antonine.rodrigue8769 Thank you for clearing that up for me.
For me it was Shift+Control+Option+Power…
See which is correct key sequence to reset the SMC for your exact model here…

When I charge the battery for the last time, do I need to leave the power adapter in for 2 hours again or just unplug? Thanks for the vid! :)
Thank you
You should really set up a screensaver if you gonna let the screen on for many hours.
Don't ever do it macbook pro 2019 - After I did once I have a charging issue...Once the macbook is unplugged and plugged it back after sometimes the battery charging status tells "NO". SMC reset is the only option I found to solve the issue but I have to do this all the every time I turned my mac on. Anyone having the same issue?
I have that as well. Did you find a solution?
Why is it necessary to change the energy saver mode for the power adapter mode as well when draining it?
So that the laplop won't switch to sleep mode when leaving it on while it drains its battery
@@Anonymous-cn6zl laplop 😆😂
I replaced my laptop battery a couple of weeks ago. It charges to 100%, but now my laptop switches off when the battery drops to about 30%. Does this process address that issue, or should is this a different problem with a different solution?
I have the exact same problem, but my new battery came with specific instructions to let the power drop to 10% before charging. I expect it's completely screwed now.
I have the same problem at about 20%. The fix is to reset the SMC. It fixed my issue for a while, but returns occasionally. My next fix is to replace the battery.
what do you mean with "switches off" ????
I bought this battery & a WD SSD & now my MacBook Pro 2012 is slower than ever with the fan running like crazy! Please help I’ve tried Everything.

Found this. Hope it helps, if you haven't solved your issue yet.
Should this procedure also used after replacing a damaged battery in a Macbook Pro Retina Mid 2012? The new battery came with ca. 57% charge and now I am supposed to turn the macbook off and then charge it till magsage is green +2h and the rest of your instructions? I thought I first need to discharge/drain the new battery by using the macbook and then charge it to 100% +2h!?
Yeah that's the instructions mine came with. Now it's fucked.
Just bought a NewerTech NuPower battery for my mid 2012 non retina MBP I followed all the steps but I forgot to leave the laptop charging for an additional 2 hours after it fully charged. But I did follow all the other steps. Should I be worried about that?
@@poweredbyowc thank you seams as it worked fine... when I was draining the battery from a full charge it got stuck at 91 percent. but when I checked it in the settings a few hours later it was like at 35 percent.. so it eventually died but when i fully charged the battery again it seem to drain fine... so I guess I am all set.
Hello.. I just swapped my old battery for a new one in my 2010 MacBook Pro 15”.. it did not come with a partial charge. MacBook isn’t charging at all. Where do I begin? Theirs no Amber light, only a green light and Mac stays on only when plugged in. Please help.
I'm really late to the party, but I had the same problem and I solved it by performing a hardware test holding D (or alt-D) while starting your computer and not releasing the key(s) until the hardware test screen appears. Performing a hardware test forced the computer to "see" the battery somehow.
My battery has not been calibrated, but i have charged it to 100% and shut down my macbook. After i turn the power on, it shows battery charged 100% but the power source is still the power adapter, not the battery. Where should I start the calibration? (i just replaced it with a new battery before i charged it to 100%)
Below is the link to the instructions on the battery calibration. If there are further questions or concerns, we do recommend reach out to our support team at support@owc.com

Will it get rid of battery recommended on Mac laptop
The notification will persist if the battery does indeed require replacement.
So I had this question for many years now, and i hope i can get an accurate answer.
1. Is it okay to leave the MacBook charging after it is fully charged/charge overnight?
2. Is it okay to use it while charging, especially when it is Fully charged?
MacSales. com And same for usage while fully charged plus charging right?
ruclips.net/video/d34p7ULZbzU/видео.html
Is there a way to completely discharge the battery without waiting for 5 hours?
Letting the system sit for 5 hours ensures that all systems are drained of power. Many users find it helpful to plan this step for overnight.
1:29 I do that too.. Good thinking :)
2:04 What is the actual reason for waiting this long?
Na Na- The reason for waiting up to 5hrs is to ensure that the battery is fully drained and discharged.
@@poweredbyowc but it runs down ill it powers off completely.. that's discharging it, leaving a "small" amount of power left... You saying it can take "5 hours" for tat "small" bit to discharge ??
In comparison, when a battery gets to 80% charged, its resorts to "slow/trickle charging", THAT never takes 5 hours, in my experience to complete.. So the reverse is kinda flawed in my view as well.. To that end, i never leave it off for 5 hours, and never had problems with my battery at all... even during a calibration...
I'll state my life on it
@@Tech-geeky can i not wait for 5 hours?
when it was discharging i shut the laptop for a bit because i forgot i was waiting for it to die but when i remembered i opened it to let it drain. is that okay? does it still calibrate?
Yep, that's perfectly fine!
Nice
I accidentally used the macbook while it was charging to 100% for the first time, will that ruin the capacity?
Not at all!
Hey I tried that but it still goes from 100 to 95 to 70 then25 to 7. Any fixes?
If you have already done the Calibration 3-5 times already and still having the same issue please reach out to us and as long as you still within the warranty period we would be more than happy to replace it as that is not normal behavior for our battery.
Hello, I have bought brand new Macbook Air and when I checked out its power cycle count instantly , it was 3. Is this normal value? Thank you
MacSales. com No I did not
MacSales. com I do not think it is display model I unboxed it myself...I heard it is ok to be 0 ,1,2 or 3 even if it is new MacBook..is that true..the ones you unboxed were always 0?
What should I do if the MacBook shuts down to 3%?
If it shuts down at 3%, that is okay. Some Macs may shut down at 3%, 5%, some will shutdown at 1% depending on the settings and how it's being used. Just continue on with the rest of the procedure to calibrate the battery and you will be rocking and rolling in no time! :)
Oh I did not know about this and I have been using my new battery. Is it ok to do this later?
We would recommend you do it as soon as possible and then we would recommend after the first time do it once a week to provide the best battery life.
@@poweredbyowc is that for anyone or just me because I did not do it.
This is a great question! Looking into this further we miss spoke. While you can perform this every week it isn't necessary. For best battery life you can perform the calibration every 60-90 days. Please let us know if you have any further question on calibration.
@@poweredbyowc thank you. You really helped me
Is it okay to not wait 5 hours??
While calibrating our batteries we found 5 hours to be the most successful, so that is what we recommend when calibrating the power management system.
I love mac, but recalibrating the batteries is a giant pain in the ass. They need to make it more of a one click process.
No cap 🧢
Do we still need this power calibration ?
Yes, when installing a new battery it is still recommended to perform a calibration.
i just instaled my battery and didn't calíbrate, this makes the computer display an incorrect % im now using it and showing the % correcto thanks to this video
Can i use it while ITS charging Back?
Great question! The short answer is yes you can! For more info, please check this article out: blog.macsales.com/27698-calibrate-and-exercise-your-battery-for-better-health-run-times/
Why we need to wait 5 hours ?
Narrator: "Leave the system shut down for 5 hours to ensure the battery is completely drained"

Outdated. There is no "Energy Saver" preferences in macOS today.
I do apologize about that however with a good few of our users using Legacy OS's we do still have this put up to assist our customers with said OS's. If you ever have any other questions or concerns please let us know at support@owc.com!
@@poweredbyowc The question would be ofcourse how to do this on newer macOS? It doesn't let you drain the battery or give you the choice to stop them hindering you to do it.
Hey Ruffex,
So we are just slightly confused. We don't know about anything about Apple's new MacOS that are stopping the MacBooks from draining. Us here in the office we use 2019 and newer MacBooks and have no issues with draining the batteries when our MacBooks are used. Can you explained what you are referring to with your question?
@@poweredbyowc Screen goes blank at 4-5% and it takes ages to get to 1%
Again I would recommend calling and talking with us directly as we may be better able to assist and determine what you are seeing, what is going on, and when having a live conversation, we have more tools readily available to help assist you.
My computer says it needs me to service the battery, how do I do that? Does it mean I need a new battery?
thanks
“This time you can use the Laptop while the batteries are charging?!?!” Except You said you could use it the first time!! Which is it?!? WTF?!
J T On the first one you can only use it AFTER it is charged to Green light but not during the Amber light (while it’s still charging to full capacity) on the second and last time you can use it even when it is charging during the Amber light phase. Hope I made this clear for you!
Whatever happened to politeness? Do you speak to everyone that way?
I followed this and totally screwed up my new Battery install
It was fine until i followed these steps
Not it says "Not Charging" when i have the AC Adaptor plugged in and full charge is showing as 90%
Bahahahaha, what have you done!
Try reseting the SMC on your macbook!
1. Turn computer off
2. Press Shift + Option + Command + Power and hold them for 10 seconds
3. Let go of all the keys and press back on the Power to start your macbook
Your SMC should then be reset!
