Microphone Battery Best Practices

Dead or weak batteries are the most common cause of wireless mic problems during a show.

For every performance

• Start every show with fresh or fully charged batteries in every transmitter, including spares.
• Don't reuse "half-used" alkaline batteries for a performance. Move them to rehearsal use or recycle them.
• Check battery levels on the receiver or transmitter display before the house opens.
• Keep spare charged batteries backstage with your spare pack.

Rechargeables

• Use the battery type and charger your system's manufacturer specifies.
• Set a charging routine: charge after every show, and label batteries or packs so you can rotate them.
• Rechargeable batteries lose capacity over time. Replace any that no longer last a full show.
• Most bodypacks need to be set to the battery type in use (alkaline, NiMH, lithium) so the battery meter reads correctly. Check your manual.

Storage and safety

• Remove batteries from transmitters and handhelds when stored for more than a few days, to prevent leaks and corrosion.
• Check battery doors and contacts for corrosion. Corrosion damage isn't covered by warranty.
• Don't mix old and new batteries or different types in one device.
