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. Review: Work as Intended - 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. ## Features - New,replacement - 3.8V,70mAh - Compatible Part number:Z55H - Compatible Model:for WF1000XM4 WF-SP900 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CCHMD1DX | | Antenna Location | Laptop | | Battery Capacity | 70 Milliamp Hours | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Best Sellers Rank | #76,666 in Cell Phones & Accessories ( See Top 100 in Cell Phones & Accessories ) #611 in Cell Phone Replacement Batteries | | Brand | Generic | | Compatible Phone Models | Not application | | Customer Reviews | 4.2 out of 5 stars 24 Reviews | | Manufacturer | Shenzhen Haihanwen Technology Co.,Ltd | | Model Number | Z55H | | Recommended Uses For Product | Laptop | | UPC | 808233499321 | | Voltage | 3.85 Volts | | Warranty Description | One year | ## Product Details - **Battery Capacity:** 70 Milliamp Hours - **Battery Cell Composition:** Lithium Ion - **Brand:** Generic - **Recommended Uses For Product:** Laptop - **Voltage:** 3.85 Volts ## Images ![Powerforlaptop Replacement 3.85V 70MAH 0.29Wh Z55H LIR1254 2PCS Battery Compatible with WF1000XM4 WF-1000XM4 WF-SP900 Headphones - Image 1](https://m.media-amazon.com/images/I/61AKZ-g1xRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome new battery life for sony wf-1000xm4 *by S***T on October 20, 2024* I had 2 basically dead sony wf-1000xm4.
