In the school assembly show that I’m doing, I have a few things that need batteries. The two Promystic Fux units, the media star remote, and the flic button. That’s in addition to two 5V battery packs, a wireless handheld mic with receiver, and the Bose S1Pro, but those get recharged daily. My show takes a lot of energy!
At the end of every week, I have a scheduled task to change the replaceable batteries of the Fluxes, media star remote, and flic button. It’s overkill; they should last the full month long run. However, changing the weekly only costs about $5 and gives me some peace of mind that they’ll always work.
The nice thing is that they are all redundant systems. The two Flux units back up each other and if the media star’s battery fails, I have the flic button and vice versa.
