Review: Exact fit, Great Price, quick shipmt direct from AMZN! - Exact fit, initial charge took quite a while, now they charge up in 40mins. Quick Ship from AMZN. We'll see how long this set last, excellent price! Review: Not compatible with OEM charger - I gave this product one star only because I couldn't figure out how to give it a lower score. This product is supposed to be a direct replacement for the Bose 40229 battery. It is not a direct replacement. It will not charge in the Bose OEM direct plug in charger. One you use up whatever amount of charge is in the battery upon arrival, it is not chargeable and is of no use. DO NOT BUY if you have the OEM charger. ## Features - COMPATIBLE WITH BOSE QC3 MODELS: Replacement battery for Bose QuietComfort 3 Acoustic Noise Cancelling Headphones, compatible with model numbers 40228, 40229, and part numbers PC40227, PC40229, NTA2358 - BATTERY SPECIFICATIONS: Voltage: 3.7V; Capacity: 140mAh; Type: Li-Po; Compact design tailored for QC3 headset battery compartment - RELIABLE PERFORMANCE: Provides consistent, rechargeable power to extend listening time and headphone usability - DIMENSIONS AND FIT: Measures approximately 1.55" x 1.05" x 0.53", perfect fit without modification; not compatible with other Bose models - PACKAGE CONTENTS: Includes 2 x 3.7V 140mAh Replacement Battery; 24-Month Worry-Free Warranty and Smile Customer Service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BXKVH2HB | | Antenna Location | Headphone | | Battery Capacity | 140 Milliamp Hours | | Battery Cell Composition | Lithium Polymer | | Battery Cell Type | Lithium Polymer | | Battery Weight | 58 Grams | | Best Sellers Rank | #437,166 in Health & Household ( See Top 100 in Health & Household ) #1,177 in 3.7V Batteries | | Brand | ROWSHEP | | Compatible Phone Models | Bose QC3, 40228, 40229, PC40227, PC40229, NTA2358 – Acoustic Noise Cancelling Headphones | | Customer Reviews | 3.5 out of 5 stars 50 Reviews | | Manufacturer | elxjar | | Number of Batteries | 2 Product Specific batteries required.
