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!
