For those of you who are sceptical of using Rechargeable battereis in radio microphones, Mike over at Church Tech Arts has done some thorough runtime testing of various AA rechargeable batteries in Shure UHF-R UR2 microphones with SM-58 capsules. Mike also includes ProCell Alkaline batteries as a comparison for those using Alkaline AA batteries .
The Powerex 2700 AA and Sanyo 2700 AA both had the longest runtime at 14 hours, eneloop came in at 11 hours, and the alkalines ran for 9.75 hours. You can be assured that quality recargeables will pay for themselves. Mike tested a set of 4 year old rechargeable AA’s and found they were still outperforming Alkaline batteries by 4 hours.
Mike has a great overview of why you may have been burned by rechargeables in the past.
