Powerforlaptop Replacement 3.85V 70MAH 0.29Wh Z55H LIR1254 2PCS Battery Compatible with WF1000XM4 WF-1000XM4 WF-SP900 Headphones

Needed new batteries after my earbuds started dying after about 10-15 minutes of use. After replacing I used them for about 2 hours and still had 88% battery life yet, so all good thus far. At the time of purchasing, these were about $7 - $10 dollars cheaper than other sellers who included all of the tools and glue needed for the replacement. Well worth the savings if you don't need the extra tools.

I had 2 basically dead sony wf-1000xm4. One wouldn't turn on at all. After replacing the batteries with these they work just like new with no issues. Super easy to install just need to be careful.

I am a victim of the Sony WF-10004 ear bud bad battery debacle. I found a video on how to replace the batteries. So far these are working fine and last longer than the 15 minutes the original batteries did.

Despite the listing saying 0.29Wh and the picture displaying 0.29Wh, these are 0.27Wh batteries. Also unlike the picture, they are Zenipower Branded, but that's OEM, so this is a good thing.

Batteries did not last. Made it a little over a year. I would not say that I use the headphones often enough that it would have worn the batteries out.

Replaced battery on left earbud of wf4 sonys and this thing is high capacity. I feel like this can go 8 + hours ... So happy I tried replacing myself instead of throwing them away.

I followed the ifixit and some YouTube videos to replace the battery in my Sony WF-1000XM4 earbuds. The battery seems solid after a few days of use. Update- over 6 months of use and still going strong! Update 2- downgraded to 4 stars. Battery’s are noticeably degrading after just over one year.

My Sony earbuds are back to their original battery life. 👍
