Well yes, I have tried regular 1.5 V batteries and no problem at all. I also tried to take out that plastic case for batteries and move the wire, check connections but it was fine. So Idk why it wont turn on :/Should be fine, I have heard of a few people where the battery cable had a bad connection at first and it wouldn't come on, but when they removed and reconnected the battery cable from the radio it started working then. Did you try alkaline batteries, has it ever turned on before yet?
I have no idea. Ask them, maybe there's a certain brand they are using.But how is it possible that some other rechargable batteries work for other people?
