Multiply the number of wireless mics that are currently in use by 1000 and that will give you the number of batteries that are needlessly being dumped into landfills. Why? Because it is now possible to have microphone batteries that are rechargeable and not compromise on performance. Rechargeable batteries can make excellent wireless mic batteries provided you know which brand to choose and how to maintain your rechargeable system with a good quality battery charger. But don’t just run to the “shack” down the road or to the drug store for cheap, ineffective rechargeables. Be certain to get the brand that pro-audio professionals have counted on for over 12 years now.
