[Elecraft] KX3 Internal Batteries

[Rich WC3T]

I took them out just as a prophylactic measure.  I *think* I know that Ni-Cd cells don’t burst/leak over time but I would rather not perform that experiment with a KX3.  

My Bioenno battery is a small price (in $ and peace of mind) to ensure that I don’t destroy my radio.   :)
