I remember this particular battery, it's a very old company, but unfortunately it is the worst battery not only in terms of performance and durability, but also in construction. I remember these specific ones, that while the device was working, they would also leak fluid at the same time. I won't even discuss leaving them inside for about a week at most; I made that mistake and they ruined my Game Boy since the electrolyte went into the circuit board. But most importantly, they would leak fluid while the device was operating. I don't know if things have changed after all these years, but personally, just seeing the name, I wouldn't buy them even for a cheap watch
