Can LR927 and SR927 be used in common?

  OK. SR927W has a large discharge capacity, SR---silver oxide--1.55V, which is suitable for the high current discharge required for the operation of multi-motor (three eyes, with second hand stopwatch) of multi-functional watches. The discharge capacity of CR927S is small, CR---lithium battery--3V, suitable for single motor drive of general functional watches. But the voltage is a bit high, try to replace the battery of the same type in the future, or don't change it for now.

Can 371 button batteries and lr927 be used together?

The model corresponding to 371 is AG6, with a capacity of 28mAh.

The model corresponding to LR927 is AG7, with a capacity of 32mAh.

LR927 is a little thicker.

The other parameters are the same.

Generally, multiple button batteries are used in series, and the mixed use of these two types may cause the 371 to be exhausted quickly and thus "drag" the LR927.

But there's no need to be so careful. They're all cheap consumables. If they break down, there's still a lot of them in the drawer, right?

I really have a lot of various models in my drawer, and it is very cheap to buy one edition after another.
