Listed are LR1130/ AG10/ 389/ LR54/390. That's it. They are a 1.55v battery. I also have a smaller battery, also 1.55v,that fit AG1/364A/ CX60/LR621W, so that won't fit either. Sorry. Have A Happy Holiday! **Q: Are these equivalent to a L621F Battery?** A: That I don't know. They are 675 and the largest hearing aid battery. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Little Batteries for Watches and Small Gadgets *by C***S on 6 March 2026* These AG1/LR621 batteries work well for small devices like watches, remotes, and little toys.
