Does KOMeter have a battery?
Yes, it has a 10 year life sealed lithium battery to power the clock. (And we know “Batteries are a source of failure. Batteries must be replaced. Batteries corrode. Batteries get forgotten. (Batteries are bad!)”, but there was no alternative, we didnt want you to have to set the clock on every power-on cycle or have it blinking 1200 or take the chance of running down the aircraft battery.
