ya.... you could

but i use rechargeables , it's not so bad to take them out at nigth (well every other night , not that thay have run down but i don't whant them to so.....) charge them over night. put them back in the morning. DD's  as well as AA's

dose save money in the long run

i still believe

I did have a question in regards to battery Voltage.  I do know that there was a thread posted a while back that briefly touched on this... but I could not find it again. 

RSMedia requires D and AA batteries.  Disposable ones run at 1.5V, however, rechargables run at 1.2 Volts.   No matter how much digging I do online, I have not been able to find a 1.5 Rechargable D or AA battery. 

Is this voltage difference going to possibly cause any issues in any of the RSMedia's systems?
