[Elecraft] KX3 KXBC3 and NiZN batteries

I have ordered the KXBC3 for my KX3 and hope to install it soon.  I know nothing 
about rechargeable batteries, and would like some guidance.  Will the KXBC3 handle 
automatic charging of any batteries I put into the battery pack? Do I just run up to 
15 VDC into the KX3 power jack and it automatically charges up whatever is inside there?

I looked at the A123 batteries referenced below and they don't look like the same 
size as standard AA batteries.  I believe the KX3 internal battery pack will only 
accommodate AA size batteries.  Do the appropriate rechargeable batteries call 
themselves AA size?

Thanks for the guidance!   VY 73, Lance
