I have a question about using rechargeable batteries in wireless devices such as microphones and transmitters. I was told by a sound company that it's not a good idea to use them. I would like to know why or if they're full of it. Rechargeable batteries have come a long way and are useful in power-sucking digital cameras so what's wrong with wireless audio equipment? Do they not last long enough? Is it worth the money in the long run (taking the hydro cost of recharging them into account) to change over from standard batteries and what type should I look to buy (2500mAh)? Besides all this, it would help save some landfill space. Our church spent almost $500 in batteries last year and I think that's a little insane.
Sorry if this is in the wrong section. It kind of has to do with microphones and I didn't know where to post it. Admin, please feel free to relocate it.

Rechargables start out with lower voltage and gradually decrease
Rechargables start out with lower voltage and gradually decrease their peak voltage over many cycles. I've found standard commercial rechargables like Everready to be unusable in our church's wireless Sennheisers after only a a few months (only a few hours of sufficient charge). If you can find better products, good for you, but I've been using standard batteries and changing them often.
Standard batteries = 1.5 volts per cell Rechargables = 1.25 volt
Standard batteries = 1.5 volts per cell
Rechargables = 1.25 volts
So you CAN end up with less voltage than a device needs.
Most of the time this is not a problem.
Try it and if it works, fine ( you CANNOT hurt anything by trying it )
