Default Cheap ESR Meter

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

Mine's a few years old now, but came with a standard 9v battery holder.
Mind, I did have to complain to Bob about poor battery life. My first
battery only lasted about 2 years ... !!

Bob.did the ESR meter kit change from using one 9v battery to 6 AAA cells?
I haven't had much problem with the 9V's battery life.
