I have a door bell that uses 2 aa batteries.
Would a 18650 work in such an application.
I don't know if 4.1 volts would be too high.
Thanks, Andy
18650 for 3.0 v application ?

How about the 18650 in series with a Si diode, such as a 1N4001 ? The 0.6V drop should reduce the voltage sufficient to be considered safe.

Ok, thanks.

How would I wire that up?
It's been a while.

Why not a 7803 with just a filtering cap ?
In your need, you would need 2*1N4148 or 1N4448, that's enough.
I already ordered the other diode.
It only dropped the voltage by .2 volts.
