bad battery moments

Dead Battery Moments.
I know we have all had those.
In the society we now live in, many things have batteries. I don't think any of us can truly list the things in our lives that we count on that have batteries we don't think about.
Until the battery dies.
For all you ladies writing this - do you have a spare battery, or charger in your purse?
Uh. Not me.

I think the most common thing we think about that is a regular battery charging moment is our trusty cell phones. But really, when they loose the charge, we grumble, but it's a fact of life, and go on.

But what of those other things that have batteries we don't think about, until it's too late.
Like today. I was at church, playing in the band/worship team, and what happens? I made it fine through our practice time, and about a third of the way through the first song, my battery died.
What battery, you ask?
The 9-volt battery to my bass guitar. My bass guitar that I use for church has an active pickup, which is powered by an 9-volt battery. I'm aware of it, but it's something that I tend to not think about.
I have had a spare battery in my guitar case for about 2 1/2 years. Just in case.
A few days ago we had a power failure in our neighborhood, and one of our house smoke detectors beeped faithfully every 3-5 minutes, to let us know that since it wasn't hotwired to a live power source in the house, the backup battery was dead. So, in the pitch black, I went downstairs and got my spare 9-volt battery out of my guitar case, and put it in the offending smoke detector, and life went on.
God has a sense of humor. Yes, for 2 1/2 years, I have had that battery in my guitar case. When did my battery in my bass guitar die? For the first time in 2 1/2 years that I didn't have that spare battery in the pocket.
We had a mad scramble at the front, the drummer had brought his bass and we plugged that in, his battery was gone, he'd loaned it out a few weeks before when the guitarist's battery died.
Oh, how we LOVE those active pickups.
Or some days, not so much.
He used needlenosed pliers to take the 9-volt battery out of some pedal gizmo, and snapped it into his bass, because his active pickup has a snap-in cover, where mine needs a screwdriver to get into.
So life, and worship, went on, with full instrumentation.

For all of you reading this, please share, what was your worst battery moment?
