Charging CR batteries seems like a bad idea.
I'm "new" to electronics, the reason for a schottky diode vs. a normal diode is that it's faster and has a lower voltage drop?
A schottky diode is very cheap to buy, found one type that cost £0.07 but shipping it cost £3.
So until the next time I place a order there, can a normal diode work?
The obvious problem is that voltage will drop below 4.7v quicker with a normal diode than a schottky diode.
