Works well.

### ⭐⭐⭐⭐ Excellent batteries at a good price
*by Q***I on January 12, 2023*

The work. HOWEVER, they arrive with a clear plastic film over them. I did not notice the film, and I thought my remote control was not working. I was about to buy a new remote, when I was packing up the battery and saw the nicely shrink wrapped film on the battery, which covers the connectors. Once I removed the film, the battery worked perfectly. I do not remember other 9 volts being wrapped this way. It came in a pack of 4, with a plastic cover, so it did not dawn on me to find a film. It would be nice it they covered the connectors with a red film or other color. Anyway, if you are as dense as I am, you have been warned :)
