Not exactly on Topic for this group, but I'm not sure where else to ask.
I've got one of those digital appliance timers, which takes (3) 357A cells.
According to most sources the LR44 is a direct replacement for this battery.
But the LR44s I have for the cat toy (Laser Pointer) are much too thin. I
can buy 357As in 'The Source' in Canada, but the price is almost the same as
the timer itself. I'd hate to buy 357As online, only to find out that they
ship me LR44s or some other skinny substitute. Does anyone have experience

thin sheet to get the thickness and cut it out
with scissors. Best is to have it at the negative
I guess *none* of your batteries are to spec. 0.22 inches is 5.6 mm, and spec

Chinese-made batteries may be shorter because the land area of China
is greater than that of the US. So the cumulative gravitational pull
of the earth tends to compress things during the manufacturing
process. Sometimes they expand again after shipping, but usually they
This is also why Chinese people are usually shorter than Americans,
