Indicator is on the receiver, 3 battery bars + Indicator blinking. Seems
like ~4-5 hours is all they'll run on new batteries, Every week is 1.5
hours rehearsal midweek, then 3-4 hours on Sunday Morning (setup +
rehearsal + service). When they first turn on, will always show full
battery, then go to actual level after about 3-4 minutes. Sometimes the
indicator blinks for 30 minutes, sometimes it will only blink for 10
minutes before turning off. When the battery is low, they'll also start
to reboot.
Last week, we started Sunday rehearsal and all mic's showed full, during
rehearsal 3 mics dropped to 2 bars. Just as service started, 2 mics
went to 1 bar, and halfway through, 1 mic started flashing the battery
indicator. Unfortunately we haven't been keeping track of when
batteries are replaced, we've always just done it as they go dead, but
trying to get batteries changed in the middle of something is just
distracting for all parties involved.
Years ago in High school, I worked with a Pro sound guy, he replaced mic
batteries before every performance regardless of use. 2 shows back to
back, new batteries before the 2nd show. You just end up with a ton of
50% batteries.

I would think you could get several weeks usage out of them.
Buy a battery tester.
I am not a fan of recharabable batts for stuff like this.
You would want a large gang charger that could do them all rather than
trust someone to come in and rotate the batts mid week I would think.
Does the mic actually make an alarm noise? Or just a visual alert on
the receiver.

At Church we use a some wireless microphones, they all use 2 AA
batteries. There is a battery indicator on the units, but Invariably,
they will start to alarm in the middle of using them. I'm pretty sure
the indicator is logarithmic, like my gas gauge, so it will spend %75 of
the time reporting full, and then quickly fail after that. So I'm
thinking about just mandating that all batteries are replaced at the
beginning of each use. We're not talking about a ton, ~20 batteries per
week.
How good are Rechargeable AA batteries, It's been years since I've last
used them, would they be worth looking into? Does anybody take half
used alkaline batteries and do anything with them other than throwing
them out?
