2 Pack CP1254 Replacement Battery for Sony Wf1000X XM3 SP600 700 900 Battery Jabra Rox BandO H5 E6 Galaxy Buds Bluetooth Headset Battery Varta ICR LIR 1254 A2 A3 Made in Germany

These were used in repairing a pair of older open box Samsung Galaxy Buds Live True Wireless Bluetooth Earbuds - Mystic White earbuds. The process was much simpler than I imagined. Part of what made this easy was the clear instruction on the page as well as the ifixit instructions on breaking down the earbuds and installing these, properly. For safety reasons I strongly advice that you carefully read all instructions before performing this on your own.The added tools were largely in my case, though the screwdriver may help, I recommend a more rigid plastic pry tool, in case you are using these for the same earbuds that I did. Definitely don't use metal on your earbuds, or you risk scratching or breaking them.Bonus that these are genuine made in Germany batteries!The old batteries wouldn't hold a charge for longer than 20 minutes, but these held a charge for a full day on the road, taking calls and listening to music, with no issue. They charged quickly, and calibrated easily with the charging case for the earbuds. These worked perfectly.

Toke about 10-15 minutes to install, the only hard part was prying the cover open for the first time.Went from 1-2 hours battery life to +6 hours of battery life!Thank god Sony made their earbud batteries easily replicable.Only thing to care for during install is to not short the battery, I did and it was heating up quick.The battery and the metal install piece are separated when everything is put together, but I disassembled and reassembled to make sure afterwards to make sure the short isn't happening.Great product!

Went in fine. Doesn’t last as long as the original but seems to have about 80% time of the original.

Easy to install and all necessary tools included. Earbuds back to performing like new with extended play time!

I have a pair of Sony WF-1000XM3 which I bought at release date back in August of 2020. I use them regularly for listening to music while at work and making phone calls. Over the 3 years of ownership, the original batteries weren't holding their charge any more. I was getting about 2.5 hours listening to music when these were rated for 6 hours.Because i didn't want to throwaway the earbuds, I decided to test these batteries. I did my research and found out that these are the same brand and model batteries as the original ones. I looked at youtube video for replacing them and did the work myself to replace the old ones.Installing is easy but you need to becareful not to break trims, and pull on cables. Once I replaced the batteries, it was a huge difference in battery performance. I am getting the OEM hour rating of 6+ hours again. I am happy I made this small investment instead of having to purchase another high set of earbuds. It's been 3 months since I installed the new batteries and they are still goong strong! Depending if these last me another 2 or 3 years, I am willing to purchase another set to keep my earbuds going!. I would highly recommend if you own a pair of WF-1000XM3.

Well, I probably should have listened to the other people's negative reviews of these batteries, but I was pretty desperate to get my headphones up and running again and kinda broke, so I took a chance. And it was exactly as others had reviewed them. They brought a little bit more battery life to my wore out headphones, but not much, not much at all. They now play for about an hour and a half maybe, instead of about 45 min, so I guess it was a bit of a improvement. But nowhere near the original battery life that they had when new. And that has been super disapointing, I followed the recommended instructions to factory reset the headphones. I even got a replacement recharging case, thinking that was the reason they weren' t charging, nope still don't get more than an hour and a half if I'm lucky. Very, very disappointed in this product, I would have saved myself a lot of aggravation and frustration had I just gone with a factory refurbished pair which can be purchased for about $55 if you look around. These batteries are not OEM quality, they will not restore the original battery life to the Sony WF- 1000XM3 headphones, look elsewhere.

Worked perfect for my Sony WF1000X XM3 ear buds. Super easy to change and the batteries are charging perfect and lasting a super long time again.

Battery life still not good. My headphones still die in an hour...
