Zero lemon had them so cheap that I had 4 extra batteries (they also had the extended batteries that would last forever but the cases were janky). I would keep one at work, one by the door to take with me and two at home if you include the one in my phone that I would swap out. I rarely charged my phone at all, just the batteries. I loved it.
I used to do this. I thought it was awesome but I was literally the only person I ever knew who did this. It was not a popular thing to do.

Most people did not do this nor needed to since the very beginning of cell phones
We literally do not need replaceable batteries in 2023
