[Elecraft] Internal battery question

[Randy Rathbun]

I have a bunch of gel cells sitting around here that have been  
subjected to stress like that and yeah, they go down in efficiency,  
but I sure would not throw them out if they are working. I might not  
get as good a time as if I had taken care of them, but they are still  
useful.

Unless it is really bothering you, I would continue to use the thing.
