17. Basically it doesn't matter. Size, maximum current, lifetime, total charge.

They can be freely swapped except for the fact that they are all different sizes physically.

This isn't true with ALL batteries, but with the little lithium cells there aren't any jobs so heavy a too-small battery won't work, they just won't last as long. Right now I have a laser pointer and a guitar tuner running on the "wrong" lithium cells and a ball of tinfoil to take up the space. The laser pointer eats tiny batteries really fast. The guitar tuner doesn't care - it draws microamps and will run until the battery dies of old age.

It MIGHT be possible to fry a laser pointer, or other LED lights, with batteries MUCH bigger than they are designed for if they include the battery resistance as part of the design. But it isn't likely.

Same size, same voltage, different capacities krispos42 Mar 2012 #10

Thanks. I think I'm getting it now.So no doubling up of the THICKER ones to replace the thinner ones UTUSN Mar 2012 #11

Yes, you'd be getting more endurance from the same voltage. krispos42 Mar 2012 #13

O.K., your last sentence clinched it for me, totally. Thanks. UTUSN Mar 2012 #14
