    Excellent quality
  

*by N***N on Reviewed in the United States on November 28, 2023*

Bought these to use baby toys in place of cell batteries.Compatible with the charger I already had and it seems to work pretty good.Hope they last longer as described but good for the money paid.

    Battery is performing well.
  

*by J***. on Reviewed in the United States on October 26, 2023*

Batteries arrived packaged in a small custom plastic box with a latch. Batteries had 3.4 volts when they arrived. I installed one battery in a small Bluetooth speaker that also has many LED lights and a lazer light. Installation required soldering to the battery. Battery had no trouble being soldered. Keep in mind that I do have professional soldering equipment as well as top of the line flux and solder. After installation I charged the device to full capacity. So far the battery has performed very well. We haven't used the device for an extended period of time yet so I'm hoping that the battery continues to do well. I've been disappointed by other batteries right out of the box. Dead on arrivals. This battery hasn't disappointed me in any way so far. I have no complaints at this time and I would recommend it to others.
