Early 2015 MBPr Battery ifixit.

Hi, i have a early 2015 MBPr in the i7/16/500GB config with the OEM Dynapack battery @ 363 cycles. I'm "only" getting about 5 hours on battery at half brightness. Coconut battery puts the health at 85.6% with a full charge @ 5632 mAh out of 6559 mAh with date of 10/26/2015. Would this ifixit battery provide an improvement? https://www.ifixit.com/Store/Mac/MacBook-Pro-13-Inch-Retina-Early-2015-Battery/IF123-054?o=5

I do not trust the ebay/amazon aftermarket batteries completely, but the ifixit one seems alright. Anyone have one installed in a MBP, and what was your improvement, and for how long?

Thanks.

 

I wouldn't worry about amazon batteries. I used 3 now in different machines and all worked as good as or better than the original battery they replaced. For example, my dell inspiron would get 6.5 - 7 hours when the system was new. I was really hard on the battery so after a year and a bit I was only getting 3-4 hrs on battery. I replaced my battery with an amazon equivalent and once installed I was getting 8-9 hrs on battery. So I gained an hr or two vs new OEM battery.

 

The no-name batteries you see on Amazon are likely produced in the same factories that make the Apple OEM ones. I wouldn't worry about it.

 

Agreed. All of mine worked perfect.

 

Your battery is 6 years old. It's true that the cycle count does not look very bad. Also the FCC (Full Charge Capacity) looks really good, about 5632mAh. Have in mind that this capacity (FCC) is the last known capacity tracked by the chip. I expect to have TI bq20z451 inside. In other words, if you keep the battery unused, the cells by their chemistry are loosing capacity, the chip is not aware of that. So, I would recommend you to perform a calibration cycle to be sure about the FCC value, to trust it or not. To perform a calibration cycle there are pro tools on the market but you can do it simple by charging the battery to SoC=100% (FC bit set) then discharge it to SoC=0% (FD bit set) then charge it back to SoC=100% (FC bit set). After such a cycle the firmware chip will update the FCC parameter and you will know the actual juice.

Personally, I would not recommend after market batteries. You can't compare the performance of Apple V7 firmware found in your bq20z451 chip + ATL cells LiPo high voltage with any after market battery.

 

Believe what you will. However, apple batteries are no different than aftermarket of good quality.

 

It would be better if you could prove what are you talking about. Just saying something for me means nothing.

Which gas gauge chip do these "aftermarket of good quality" batteries have ?
There are Apple batteries with ATL cells having more than 1200 cycles and still good FCC. Do these "aftermarket of good quality" batteries reach such number ?

 

Or, conversely, you can try to prove they are NOT. works both ways. Yes, the aftermarket batteries do just exactly as the original apple batteries do. Apple does not have some magical battery technology. They are produced in the exact same place as the aftermarket versions. They will just try to tell you otherwise.

 

I was expecting such an answer, probably no arguments, or even more, no idea what is inside of a laptop battery.
I am not an Apple fan, I am just repairing laptop batteries. Inside of Apple batteries, the most used chip is the Texas Instruments BQ20z451. This gas gauge is not new, quite old, it is actually the second TI generation of gas gauge chip using Z impedance tracking algorithm. But Apple changed the firmware, they are using V5 firmware starting from 2012 to V10 firmware since 2019. Their firmware is really good, in combination with the ATL LiPo HeV 4.35v cells, such batteries can last 1200 cycles or even more losing only 30-40% of DesignCapacity.

I had in my hands lots of non-genuine Apple batteries, they have Chinese poor non documented gas gauge chips with poor cells. You don't need to look at the Apple brand, just open a random Apple battery later than 2012 and you will see. If the TI BQ gas gauge family chip tells you nothing about the technology or the ATL cells then it's fine, continue saying aftermarket batteries have the same quality as genuine batteries. Not only in Apple batteries but in most other brands, the situation is the same. Even there are no BQ chips, there are Renesas RAJ240, R2J240, MAXIM 17XX and so on.

I am programming laptop battery chips almost daily using a PRO device: https://www.laptopu.ro/product/professional-laptop-battery-analyzer-nlba1 . What is your know-how in laptop batteries ?

 

Guess what, what chip that is inside does not matter if 1. the battery lasts as long per charge, and 2. The battery lasts longer age wise than the original which is what I have personally observed replacing batteries. I don't cut them open, why? 1. I don't need to because i don't care what's inside...and 2. you are dumb for doing that since they can explode. Please, you can keep the "technical Jargon for yourself". Personal experience tells me otherwise.

 

Please stop talking about something you have no idea about, clearly proved in two sentences. I know why you don't open a laptop battery because you are far from engineering or you could damage your fingers. Laptop Battery Chip Programming has nothing to do with the explosion, you are in another world. Probably you heard something about the cells and explosions but you are out of anything is related to a laptop battery. Am I dumb because I provide you the information you never heard or are you dumb because you didn't say anything useful about laptop batteries ? Stop being a poet ("I have personally observed") and come to the technical world with technical arguments. Internet is full of personal thoughts.

 

thanks for providing your superiority to me. I bow to you. Anywhoo. you spew silliness.

 

When will you start posting good technical things ? You are on a technical forum, did you miss that ?

I am pretty sure that people are interested in seeing what is inside of an aftermarket battery and what is inside of a genuine battery. What are the differences ? If none, prove why they have the same performance. Let's compare your good aftermarket battery with one genuine battery, forget about Apple, take Dell or Lenovo.

Post something useful for people and stop posting poems on a technical forum.

 

Ok, first hand experience. Please tell me, your NON technical experience with aftermarket batteries? not opening them up where 99 percent of people here give two F&@Ks about. I have used at least a dozen aftermarket batteries in apple, dell, acer, HP computers.

GUESS WHAT. They all out performed the battery they replaced. My son's macbook air, got about 30 - 45 min of extra screen time over when his macbook was new. His notebook is a 2012 model. he got 3 years out of that battery before it failed. He is still using the replacement battery to this day and it still keeps 95 percent of the charge originally obtained.

Next up, my dell 5368. Original battery lasted less than 2 years. Replaced with an aftermarket version still hold 8 hrs charge and gets one to one and a quarter more hrs than the original.

Then there is my other sons acer S3. Battery croaked in that, again I replaced it with an after market one. 4 years on that battery and it is still hold complete charge. It also gets above the original batteries screen on time. So....enjoy taking apart batteries and comparing them internally which DOES NOT MATTER. I will save lots of money, have better battery life and longevity and laugh at the people like yourself, that are "technical".

I have also replaced plenty of batteries in other devices including tablets, phones, notebooks etc all with aftermarket ones. They are all fine if not better than the originals. Best part is lack of swelling with the aftermarket ones. Maybe that amazing Texas Instruments chip is not as good as you think in controlling charge.

 

I usually repair only original batteries since my equipment (NLBA1 device) can only analyze and program genuine laptop battery chips. Even that, since 2012 I have received a lot of non-genuine batteries. I was able to open, analyze and have an idea about the most common issues. I am really interested in what aftermarket batteries you have, I want to buy one, analyze it, measure the real capacity and check the performance.
