I really don’t mind paying extra for a better product. However, I can’t tell if these batteries are actually better quality or pretty much the same as eBay batteries with a fancier packaging.

Where are the battery sourced from and what guarantees that I have the battery will perform better then say batteries on eBay/Amazon that are sell for like $15?

Reason I’m not going to Apple is because it’s very inconvenient for me.

Batteries are already the weakest link in the aftermarket industry. With the recent admission by Apple that they were throttling devices when the battery was weak, there has been a huge global demand for replacement batteries.

I suspect that that with this excessive demand, lower quality batteries are making their way through the supply chain where they otherwise wouldn’t. iFixit has a great reputation when it comes to replacement batteries but shipping them can be an issue. They may charge more but you are paying for a vendor that does thorough quality control of their parts and really stands behind them if you ever have any issues.

When you see stuff on Amazon or eBay, you are generally seeing the bottom of the barrel parts. These are the parts that pretty much every other major vendor has refused. Vendors do random checks of available lots and if the defect rate is higher than they’d like to see, they will pass on the lot. It doesn’t mean they are all bad though and it doesn’t mean there aren’t any good parts in those lots.

So yes, you could save money by buying on Amazon. If you have a tight budget or don’t want to spend too much on an old phone, by all means order those parts. But there is a very real probability that you will receive a crap part and if you do, you may have a hard time getting an exchange or refund.

YES! Pay the extra money, get a iFixit battery.

I’ve seen far to many devices totaly ruined from garbage batteries.

I’ve used multiple iFixit batteries from phones to laptops and have been happy with ALL of them.

I trust my local Ifixit store 100%. We had an 2nd generation I-pad that was put away for several years. When it was brought out for my granddaughter to use, we had forgotten the Apple ID and Password, and without the original receipt, Apple would not help us. They suggested we get a copy of the reciept from the store we had bought it from 8 years ago, that went out of business 6 years ago. For $35.00, they removed the need to use any type of password or user ID for my granddaughter to watch her videos. Happy granddaughter=happy home.

battery — Is it safe to buy MacBook Pro batteries on eBay?

My 15″ MacBook Pro 5.1 (late 2008) battery is inflating to the point of nearly breaking the unibody battery cover, so I’m really into replacing it as soon as possible. There are loads of these batteries on eBay (mostly UK sellers with high reputation) that cost less than half of the price I’d have to pay for a battery on a local Apple reseller store.

My question is: is it safe to purchase batteries for MacBook Pros on eBay? Are there any known issues or ripoffs that I should know of?

  • battery
  • hardware-recommendation

That depends on the product. I have gotten both good and bad batteries on eBay.

If it comes from China, Japan, Korea, or any other Asian country, it may very well be a fake. I have ordered several from those countries, and most of them ended up not even being detected by my MacBook.

Filter the listing so it only shows auctions within your own country. Check the seller’s ratings and their reviews from previous sales of the same product. Finally, make sure they have a good return policy in case your battery doesn’t work.

As for the name-brand vs. off-brand question, you can get good off-brand batteries, and bad name-brand batteries. It’s like gambling, but the chances are closer to 50/50.

Another option for longer term (after you have determined why the battery is expanding like it is) may be to see about getting one of the Newer Tech (or other known manufacturer) batteries for your MBP, as they have longer life ratings for the charge. Newer Tech is available from Other World Computing (www.macsales.com), and I’ve seen it from a few other online sites as well. (I do not work for OWC, but have been very pleased with their products and service) The NewerTech ones I’ve checked on are rated at higher mA ratings than the original Apple batteries.

I’ve purchased new Macbook Pro batteries twice from Ebay Powersellers. Both had the same capacity or slightly higher. My MBP is has the model identifier 3,1.

  • The transaction went fine both times.

  • After a few weeks of usage I gave good feedback as there were not problems with the battery….. that was two early:

    • The first battery expanded too much. It would still fit into the MBP, but the dent affects my MBP in a way that I cannot click with the touchpad when using this battery.

    • The second battery dropped it’s capacity to 67% after only 20 cycles.

I ended up purchasing an original battery. The end.

I would go to your local Apple Store right away as a past Apple Genius that would be replaced in most cases your battery should never do that.’

You can also call 1-800-MY-APPLE and talk to Apple Care reps tell them you are afraid it’s dangerous, It will get taken care of.

Actually, that’s pretty normal for an old battery or a battery that’s been used heavily. AppleCare may replaced your battery under a Customer Satisfaction Code, but that depends on the mood of the AppleCare representative that you talk to at the time.

If your MacBook Pro is still in warranty and you take it to an Apple Store with a third-party battery I highly doubt they’ll do any repairs under warranty — Apple is pretty tight regarding third-party components.

I’d avoid getting a third-party battery and just stick with one you buy from an Apple Store or an Apple Authorised Reseller.

Old question, but since other people may stumble here: I suggest buying on amazon.co.uk, and search for some brands that are already known for their batteries in another fields/products like Anker: avoid completely no brands from ebay.

Analysis of faulty laptop batteries. Electric cyclist’s notes / Sudo Null IT News

Hello.

By occupation, I have been repairing and assembling Li-ion batteries for electric bicycles for more than 6 years.

I often have faulty laptop batteries that are given away by computer repairmen for little money.

This is how they look after parsing:

I would like to note that most manufacturers make plastic cases in such a way that it is not possible to carefully open it without breaking it into pieces. The only exception is Acer laptop batteries. The top cover can be removed without even breaking the latches. nine0003

The cells are easily removed, sometimes it happens that the manufacturer adds a lot of sticky glue, which, sometimes, cannot be cut off with a scalpel without damaging the heat shrinkage of the elements. But these are trifles — insulation is easily restored with adhesive tape.

With the help of simple devices, a capacity test is carried out:

Charge current — 1A
Discharge current — 0.5A

The error in measuring the capacitance of this Li-500 lithocal is about plus or minus 2%. Tested on reference cells of known capacity. To sort cells by state, these parameters are enough. nine0003

I have no way to evaluate the state of the protection board — charge-discharge controller (I throw it away immediately), so let’s move on to the state of the cells.

  1. Manufacturers in budget laptops most often put cells from Sony, Sanyo, Samsung, Panasonic with a capacity of 2200 mAh, 2600 mAh. Occasionally come across 2000 mAh, as well as 2900 mAh, 3100 mAh. All chemistry is cobalt, low-current, the discharge current according to the passport is up to 2C.

    The number of cells varies from 4 to 6, occasionally there are three-cell, 8-9cell batteries.

  2. Voltage measurements immediately after disassembling the case show that most often the cells are discharged, sometimes very deeply (from 2.7V to 0.5V). The laptop controller rejects such batteries, although in order to bring them back to life, it is enough to “push” them a little by supplying a very small charge current — about 0.01A (of course, I know that it is considered that it is impossible to discharge a cell below 2. 75V, since it becomes However, in about half of the cases, an element that has even been at the level of 1.2-1.5V can be restored.The capacity can be up to 95% of the nominal declared. In 6 years, there has never been a fire or subsequent problem with such refurbished cells)
  3. There are situations when out of 6-8 cells — 4-6 are charged (3.7-3.9V), and two are at zero. This situation is the most interesting for me. From practice, branded Japanese and South Korean cells wear out at the same time, without imbalance. In the following, I will describe my assumptions as to why this might be the case.
  4. Very often, cells sitting at levels of 2.2-2.4 V, after pulling with a small current and subsequent discharge-charge control cycle on the device, show excellent parameters: almost full capacity, low internal resistance (not increased for their chemistry), no self-discharge. the same time it happens that the cells after parsing show 3.6-3.9B (the charge level is from 40 to 60%), and after putting them on charge, they begin to get very hot and transfer all the current pumped into them into heat. They are in the trash.
  5. The final yield of cells that can be reused in lightly loaded assemblies, in flashlights is about 40%. The rest do not pass the test for capacitance (less than 80% of the nameplate), for internal resistance (more than 80 mΩ per DC), for self-discharge (more than 0.002V per day)

Thinking about why laptop batteries die. nine0003

It is well known that the best conditions for long-term storage of Li-ion batteries are 5 degrees Celsius and 40% charge level (3.5-3.6V).

Temperature above 30 degrees and 100% charge level is the enemy for Li-ion!

batteryuniversity.com/index.php/learn/article/how_to_prolong_lithium_based_batteries

Notebook manufacturers have designed it to be the other way around — a laptop that mostly runs on mains power keeps the battery at 100% (4.2 and sometimes 4.35 C) and additionally warms it up with hot components — a processor, a video card. As a result, the battery, even without cycling, dies in a year or two due to the acceleration of chemical reactions of electrolyte decomposition and electrode degradation. nine0003

In addition, I did not see balancing resistors on the discharge-charge controllers, as is done on the BMS of electric bike batteries. The cell, which is closer to the processor, heats up more, it has more self-discharge. An imbalance begins that nothing can stop. After several cycles, one of the sections goes to «zero», while the others are still serviceable.

From this follows the recommendation — immediately after buying a new laptop — discharge the battery to 40% (not necessarily exactly, you can even 70%, the main thing is not 100%) — and put it on the shelf. It is better to do extra charge cycles (this can be done hundreds of times without noticeable wear). Then, even years later, it will practically not wear out (tested on more than one personal laptop). nine0003

Of course, if there is a possibility of a power outage in your area or the laptop is often used autonomously, then this advice will not work. In some cases, the cost of losing information during a power outage can be much more expensive than increased battery wear.

used laptop HP Chromebook 11 G4. The history of my purchase from ebay, as well as instructions for installing Gallium (Ubuntu) OS on it

Hi all. Today I will talk about my next purchase. This time we will talk about buying a used HP Chromebook 11 G4 Chromebook, as well as changing the ChromeOS built into it to the more versatile Gallium OS. nine0009
Also in the review there are offal, a little collective farm (no way without it) and conclusions. Interesting? Well then, read on.
The next evening, rummaging around on ebay, the thought came to my mind, should I buy myself a Chromebook? I looked at the prices. Prices are more than adequate (low). For $30-60 you can choose from a bunch of devices. Yes, they will boo. But for me it’s not scary.
Why do I need a Chromebook? Yes, in fact and primarily out of curiosity. Well, the second argument, it will be a bedside device on which I can watch YouTube videos and read websites in the evenings (at this moment my teclast t30 tablet tensed at the thought that it could be left without work)
Of course, you could just download ChromiumOS and put it on any laptop I have. But the soul of a shopaholic demanded a new device. Therefore, after spending the evening choosing, I bought myself an HP Chromebook 11 G4. The choice on it was due to several factors. First, the price. 50-60 bucks is the amount that still doesn’t seem so big (even at the current exchange rate)
Secondly, the amount of memory in this device is 4GB, against 2GB for many other options. Thirdly, the Celeron N2840 processor, which, unlike Tegra and even more so RockChip, has longer support (I read this on the Internet and reviews)
And fourthly, I liked the look of this particular instance. True, the seller, a bad radish man, did not send exactly what was in the photo, but I am still trying to figure it out with this.
The declared characteristics of the laptop:

The base version of the HP Chromebook 11 G4 has 4 GB of RAM and 16 GB of ROM, as well as a TN matrix-based screen with not very wide viewing angles. The screen has a diagonal of 11.6 inches and a resolution of 1366×768 pixels. nine0009
The HP Chromebook 11 G4 laptop is built on an Intel Celeron N2840 processor with a frequency of 2.16 to 2.58 GHz on two cores, it is also busy with graphics processing. There is nothing more interesting here, but you can still note the presence of USB 2.0 and USB 3.0 ports, a card reader, Wi-Fi 802.11ac and Bluetooth 4.0 modules, and an HD camera for video calls over the Internet. Plus, somewhere in the body built-in microphone. All of the listed iron, together with 36 W / h batteries, weighs almost 1.3 kilograms. The dimensions of the HP Chromebook 11 G4 laptop were 300x206x20 millimeters. nine0074

As a result, the choice is made. Chromebook purchased.

In the description of the goods there were pictures of the seller. Here they are:

But in fact, I received a slightly different product. More precisely, in a different state. For this, I am already negotiating with the seller.
Since the lot did not have direct delivery outside the US, it was bought to an address in the US. He went to me as part of other goods in a large package. I already talked about the soundbar, it was also in that package.
The Chromebook was in this box:

Inside was the Chromebook itself and the charger.

We remember the photos above that were in the lot. But in this form I received the goods:

One leg is missing:

The case has abundant traces of use by the previous owner:

The case inside is covered in scratches:

Display bezel scratched. There is one big scratch on the display itself:

Such are the things. Sorrow is sad. nine0009
But on the other hand, someone will say: what did you want for those 50 bucks? And perhaps he will be right. Although if the prod put up real photos, I would consider whether to take this lot, or choose another one.
But okay. What I got is what I have. Now about the Chromebook in general.
It looks quite compact. The screen itself is of good quality. The dimensions of the chromebook itself are 30*21cm.

On the right we have a 3.5mm jack, two usb 2.0 and an HDMI output

On the left is the charging connector and the port for SD 9 cards0009
The rest of the sides are empty, there is nothing interesting there.
The screen has a diagonal of 29.5 cm. with dimensions 25.5*14.5cm.
The Chromebook itself has ChromeOS installed. It is essentially one solid browser.
And, for example, for watching online videos, checking mail, reading websites, this is more than enough. (well, think for yourself how much time we spend in the browser, and how much time we spend in other applications on our PC)

In general, this axis is enough for many tasks. And I even used it for a few days. But when I bought a chromebook, I thought that I could put apk files for android on it. Unfortunately, after receiving and actively studying the ChromeOS topic on w3bsit3-dns.com, I realized that I have a device in which there is nothing but a browser. nine0009
On the one hand, for a bedside device, this is not a very big problem. (and my laptop really settled near the bed) On the other hand, I want to install applications. The same Skype, another browser and player, maybe even simple toys. Therefore, I decided to get confused with reinstalling the OS. Judging by the topic on w3bsit3-dns.com, people mostly put NeverWare CloudReady on old Chromebooks. But this OS also has a bunch of limitations. And in one of the messages, I purely accidentally stumbled upon the mention of the Gallium OS. It’s Linux for Chromebooks. According to the statements, it is very light, but has all the necessary functionality. Began to look for how to install it. Unfortunately, there are simply no Russian-language guides on the Internet. nine0009 The OS itself is found without problems and even downloads (you need to choose your processor architecture)

To install on a flash drive, I used rufus

But how do you install an OS on a Chromebook? there is no info. But there is a desire. Began to smoke English-language forums. And I came across several videos on YouTube.
Specifically, it completely suited me here:

Approximate course of action.
1. You need to disable the OS check in the laptop itself. This is a simple if and is done quickly. nine0009
2. You need to install the update file via the command line and install the BIOS.
This is done easily. But provided that the laptop has BIOS write protection (Write Protected) removed. And here it is implemented, let’s say so ironically. It is necessary to remove one bolt that is responsible for the WP function. And for this you need to disassemble the Chromebook.
At the same time, there is a chance to find out what is inside him.
Therefore, I arm myself with an ordinary Phillips screwdriver and begin to disassemble. This is done easily. I unscrew all the screws on the bottom, turn the Chromebook over and remove the top panel along with the keyboard. here, by the way, you have to be careful because there are two cables on the top panel (keyboard and touchpad), they can be torn off if you pull hard. nine0009
As a result, I see these intestines:

Pay attention to the condition of the thermal paste:

A cursory examination of the motherboard gives me information that it does not have markings on which screw is responsible for write protection. Searching for the keywords «HP 11 G4 WP», «HP 11 G4 Write Protected» and similar also does not provide information. Oh, and I got involved in the problem.
As a result, I turn on the brain, and by elimination I find the right screw. It differs in size, and it also has a contact pad with 4 contacts. Anyway, this is what I need. Remove this cog:

I put the chromebook back together, go back to the command line and hooray! I guessed, the protection is removed, you can install the bios:

Bios got up without errors. I reboot the beech, select the already inserted flash drive in the boot section and you can install the OS Gallium

At the first start, the system starts in Live mode without installation. It is already being installed:

The installation itself takes about 15-20 minutes. And here is the moment HE. I have a full OS chromebook. Let this OS and Linux-like. nine0009

A quick test of the system shows that everything works more than adequately. Let’s just say it flies. quickly and properly. The browser is the Chromium browser, and this is a full-fledged desktop browser:

The same YouTube allows you to watch videos in any format:

In the test, even 4k videos roll without any problems.
All other browser functions work the same without any problems. In addition, I can now install Firefox Quantum without any problems, in which all my bookmarks and passwords are located (yes, I’m not chrome-dependent). To do this, there is an application manager right there in the system:

I also think you can even install Wine and use some Windows applications. But an attempt to install the first available wine from the manager resulted in an error. here you need to figure it out:

In general, this is a full-fledged OS with the ability to use many features that ChromeOS does not have.
And I’ve stopped there for now.
Conclusion:
What can I say about the results? Well, firstly, I do not urge you to immediately repeat my path. In addition, as you can see with the seller, I was not very lucky. nine0009
But as a result, I got a netbook with a linux system for 60 bucks, which works quickly and adequately. The battery is not new. The promised 10 hours of work is not there. But 4-5 hours it still works. And that’s enough for me.
Would I repeat this experience if I knew in advance that I would have to be so perverted? More likely no than yes. And besides, my desire to use ChromeOS in the end did not come true (well, what are these couple of days? This is not enough for a full understanding of the system)
Do I recommend buying old Chromebooks? Probably not.
