More Lounge knowledge needed: those coin sized/shaped batteries 2016 2025 2032 [View all]

[UTUSN]

I'm not lazy and will be doing my own laboring research on this internets thing, but very likely somebody already knows the answer, so why not.


Let's see whether I can be clear: Are the 2016 / 2025 / 2032 used for *different* apparatuses (pl?) or do the different numbers indicate the POWER or like that of the indicated battery and each apparatus can only use a "dedicated" 2016 or dedicated 2025 or dedicated 2032?

Am I being clear? Like, there's this little penlight/keychain light that comes from the factory with two 2016 batteries. Does this mean that ONLY 2016s can be used in it? Or are the 2025 or 2032 numbers indicative of stronger (or lesser) POWER and can those be used (with more?) power?

Later!1 Thanks.
