Hello,
I'm more of a software-guy but I have a microcontroller project
underway that is intended to run off battery power. The MCU draws
about 30mA at 3V and I had intended to run this off a CR2450 battery
that is said to provide about 600mAh at 3V. I thought this would give
an operating time of around 20h, which is acceptable.
However, when I'm reading the specs for a CR2450 battery, it says the
maximum continuous discharge current is only 2mAh! The wikipedia page
for battery types lists the CR2450 as recommended for "high" current
devices around 30mA, so I'm a bit confused...
Is the CR2450 adequate for my application, or do I need to use a
different kind of battery, maybe two AAA or something like that, which
are able to give more current?
Thankful for educational advice!
