@jogihara & @scotth

I know its not easy to test the batteries but we are seeing more and more bad ones in the Answers forum. Its now getting more visibility!

Is there anything you guys can do to tighten up the QC.

Update (05/18/2019)

Sourcing high quality aftermarket Mac laptop batteries has always been a challenge, as many of the manufacturers in China are trying to produce a very inexpensive product catering to emerging markets (South Asia). We looked into several alternative suppliers in the past year, and found their products to be unsatisfactory — and failing to meet the specifications of our current supply chain (which at least provides batteries that match OEM capacity specifications). We have audited our supplier’s testing procedures and found them to be reasonably thorough.

That being said, we have identified particular models that have higher failure rates, and we are regularly providing feedback to our supplier so they can work to reduce those issues. We have been pressing them on quality issues more aggressively in recent months, and I am going to be making another visit to their facility in about a month. To be fully transparent, the models we’ve been seeing the highest rate of issues are:

MacBook Pro 15” Unibody (Early 2011-Mid 2012)

MacBook Pro 17” Unibody (Early 2009-Mid 2010)

MacBook Pro 17” Unibody (Early 2011-Mid 2012)

MacBook Pro 13” Retina (Late 2012-Early 2013)

For a period late last year we were also seeing concerning return rates on the MacBook Air 11” (Mid 2011-Early 2015) battery, but those issues appear to have been resolved — with no significant issues on our most recent 7 shipments.

I have a high degree of confidence in all of our other Mac laptop batteries, and our four bestsellers – the MacBook Pro 13” Unibody (Mid 2009-Mid 2012), MacBook Air 13” (Late 2010-2017), MacBook Pro 15” Retina (Mid 2012-Early 2013), and MacBook Pro 15” Retina (Late 2013-Mid 2014) – all have very low customer return rates.

I am unable to provide a detailed analysis of OWC’s replacement battery offerings. Anecdotally, I have had one of their MacBook Pro 13” Unibody (Mid 2009-Mid 2012) replacement batteries in my work laptop for the past 7-8 months, and I have been unimpressed by the battery life. I only get about an hour and a half off a full charge, while comparable laptops in the office with our own replacement batteries last much longer. But again, this is just one model, and quality does seem to vary considerably across different model batteries. We are familiar with the company that assembles OWC’s batteries, as we considered using them as an alternative supplier for our own. However, we had some reservations about the quality of samples we received from them and decided not to pursue them further.

TL;DR - We have a high level of confidence in the quality of the majority of our Mac laptop battery product line. There is a limited number of models that we have experienced higher rates of customer returns than we consider acceptable (above 5%), and we have been working with our supplier to address the cause of those problems. We obviously stand behind our product in offering the one year warranty. The volume of Mac laptop batteries we have sold has increased markedly over the past year, and the higher frequency of forum posts related to batteries seems to be reflecting that — rather than an increase in the rate of issues with our batteries .

Hope this helps! :)

@danieldemeter - Thank You in addressing the concerns we are seeing in Answers!

I'm sure its not easy to get quality batteries sourced from the battery suppliers. And I'm willing to bet most of the issue is the supply of the raw materials availability & purity as the demand is likely outstripping the supply.

Sadly, failed batteries do get more visibility. While the failure rate might be in tune with the quantity sold by the percentage, it appears larger when you don't know the numbers statistically.

If you can't do deeper QC, maybe the paperwork shipped with the battery needs to be reviewed so the customer is driven better to the store return page when a failure has been encountered. Maybe offering a more effective return process as that maybe a factor here. Does it make sense to offer inflight swap-outs?

And lastly, maybe having someone within iFixit take the time to review the concerns linked in this persons post to see if there was any way to address the posters concerns that might help future buyers not get soured on iFixit.

Some side notes:

The Quality Parts page needs a bit of an update for the newer storefronts.

I've noted the battery firmware reports via CoconutBattery odd values on the iFixit batts. Can you get the suppliers to plug in the iFixit name as the supplier? Also the firmware version and S/N's are also a bit wacky as they are not true values.

Thank You ifixit! I’ll admit it I tried to “cheap” out and ordered a 2 day delivery replacement battery for my late 2011 MacBook Pro 17”. The battery was less than stellar. (Actually bowed enough to put undue pressure on my touchpad) returned it, ordered the ifixit battery, for like a glove. Thank You. Now I have other issues (graphics GPU) but that’s not iFix it’s fault. Thanks again.
