Here’s how to get maximum life from your wireless mic batteries
Remove batteries when the mic will not be used for more than a couple of days.
Always replace all batteries at the same time if your mic uses more than one battery.
Don’t count on the battery life gauge on your receiver.
Get a volt/ohm meter so you can do accurate voltage tests.
Save used, but not completely expired batteries for rehearsals and non-critical events.
Don’t mix batteries of different brands or ages in the same wireless device.
Never use carbon batteries in a wireless microphone.
Make sure 9 volt batteries remain capped when not installed in mics.
Use batteries that are date coded for maximum shelf life.
