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.

### ⭐ Not compatible with OEM charger
*by A***R on February 21, 2026*

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.

### ⭐⭐⭐ New Batteries will not charge in old style charger
*by M***E on June 12, 2025*

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!
