Knowing when it's time to change a battery?

Always the day before a gig.

Good time to change your strings too.

Murphy's Law. If you don't It'll surely die in the middle of a set.

If not die. At least sag enough to make your nice acoustic sound like it's being run through a fuzz box.

I bought one of these and it's very handy. But for some reason it doesn't work plugged into the output jack of my guitar. Touching a battery to the terminals on the side of the unit works great.

Hmm, that kind of defeats the whole purpose of it ... But the idea's great.

How about setting up an alert on your phone for every 3 months(or similar frequency)? Or if you’re playing frequent gigs, change the battery at string change time. I’d rather change out a half used battery than have one go dead during a performance.
