Like most hams, I have some old equipment. To be precise I own an FT-911 walkie, who uses from Ni-Cd batteries. The original battery died many years ago. Because nowadays it is difficult to get Ni-Cd batteries, I rebuild the pack using Ni-MH batteries instead.
No matter what brand of batteries you choose, or what kind of charger you use with them: they will be dead in just few months. I'm really concerned about the quality of Ni-MH batteries today. Because I really got tired of replace the battery cells, I looked for a different kind of battery. What about Li-ion batteries?
