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

Solid product, functional and reliable

Absolute junk. Neither of the two will charge even a little. worthless

The batteries were compatible with the original Bose QC3 headset.

Purchased two spare batteries for my Bose QC3 headphones after the original OEM battery died. I charged in my Bose OEM charger with no problem. It fits perfectly in the charger and perfectly in the headphones. I used one battery 5 hours to Las Vegas. Used the second battery for 5 hours to return to New York. Works perfectly. Next test is a longer flight.

If you have a very old-style battery charger that plugs directly into the 110 v outlet when charging the battery, you may have to buy a new style charger with a detachable power cord as well. I ordered a set of replacement batteries from two different suppliers and none of them would indicate that they were charging when plugged into my old charger. They would power up the headphones though. I bought a new style charger and they all charged OK and worked fine when installed in the headphones. There must be a very slight dimensional difference in the two chargers even though they look the same! Also, the new batteries from ElXJAR had the part number label on the front side of the battery and it would not fit in the charger, you have to peal it off and put it on the rear side of the battery!

New review - Update. The batteries do work. I found out that if I left the batteries in my Bose charger longer than overnight, they would charge up normally and have been using them without any issue.For some reason the charge light will go out as if fully charged, but hey are not. Honestly, I don't know if my original Bose battery reacts the same way. Anyway, the alternate batteries work just fine.I gave 4 out of 5 stars only because the amp capacity is reduced from the original large capacity battery of the OEM.Original review - I have an original Bose charger and 2 Batteries. One of the originals was failing to hold charge, so decided to give these a try.Both of the new batteries do not work. They fit perfectly into the Bose headset.I attempted to charge each one multiple times overnight and in each case after inserting into the headset and powering ON, the power LED would flash indicating low charge. I'm back to using my 1 good original with no problems.They don't offer free return shipping, so I'm not going to pay to ship them back. I just consider it a loss.Don't buy these and waste your money. Of course if the company wants to send me another set FOC, I will update this review.

Cost was low

Does not work in the headset. I sent them back
