[Yaesu] FT-50RD Batteries

[Dennis H. Morales]

Hi Folks ..
 
I have an FT-50RD that is about 4.5 years old and it came equipped with
the FNB-41 battery and I purchased the FNB42 battery at that time.
After light usage over those years both batteries now will not take a
charge.  I tried the desktop charger and the 12v car charger with the
same results.  
 
1.	Is 4 to 5 years all I can expect from these batteries?  
2.	Is there a way to 'condition' them to extend their life a little
longer?
3.	Has anyone tried a different brand of battery with a better life
span?
 
These guys are not cheap.  41 goes for $59 and the 42 sells for $63 at
AES.
 
Thanks in advance for any and all your help!
