Apologies about that!
I was replacing the batteries about once per 3 months with typical
use, though some people complain that they hardly last any time at
all. Maybe they always leave the meter on until it turns itself off?
The 78L05 regulator can be replaced with a low dropout voltage one,
which extends battery life a bit.

Cheers
Bob

Mind, I did have to complain to Bob about poor battery life. My first
battery only lasted about 2 years ... !!
