HQRP 2-Pack Battery Compatible with Bose PC40229 PC-40229 40229 40227 NTA2358 2358 QC3 QC-3 Quiet-Comfort 3 Acoustic Noise Cancelling Headphones

I was skeptical about these batteries having seen the negative reviews, as that is where i tend to gravitate when first considering a purchase and there was a fair many of them. I don't know about their experience but these work perfectly in my Bose QC1 40227 headphones. I have had these for about a week and have been through a charge cycle with both batteries and they have worked flawlessly. Though not continuous, but at stints of about 30 minutes at the longest and repeated on and off shorter cycles I got about 5 hours of use with the first battery out of the package before needing a charge. They both work flawlessly with my original Bose charger. I can't attest to their overall longevity, but that's the gamble with any battery. For now I am a happy camper.

I took a chance on a 2 pack. Packaging was mangled and only one dead battery inside. Wasted money.

I wanted to like these batteries. I had an old set of Bose headphones that I had not used in years that were still in great shape. I only had the one original Bose battery and wanted some new backups. At first, the batteries seemed to work well. However, after charging them a couple of times the inner most contact on my charger broke and would not charge the batteries anymore. I never had an issue with the original Bose battery that I charged many times over the years. I chalked it up to being a fluke. I bought another original Bose charger that was in mint condition and used it to charge my Bose battery with no issue. I then tried charging them HQRP batteries and had a problem with them making a connection to the charger. When I pulled one of the batteries out of the charger the inner most contact broke again. When I compared the size of the metal contact pads on my original Bose battery to the HQRP batteries, the HPRP batteries metal contact pads are smaller which may be causing the charger contact to stick on the surrounding plastic and break when removing the battery. Now I am stuck with two useless battery chargers and two batteries that I cannot charge.

Anyone nervous about buying these for the Bose QC3 headphones, with the original plug in wall charger, should not be. Worked perfectly for me, and charged up just fine.

Worked fine in BOSE headphones. No problem charging in the BOSE wall charger. Seem to hold a charge just fine.
