Nicad Collecting

I have eight old AM radio sets they date back from 1970 to 1980 something. One is a Futaba with a transmitter that takes modules. So I acquired several FM modules and it works great. I went through six of them and ended up with seven dead cells, two of which were showing signs of leakage and five were just dead. Most of these were from transmitter packs. The first picture is the serviceable battery packs I ended up with. The second picture is the dead batteries. The last picture is of the General Electric button cell pack out of the 1970 Kraft 4 mode 1. Last winter for five months it held a charge, as you can see several of the cells separated. All the other radios had replacement cells in them. Two of the square packs had no voltage reading and after replacing a cell in each they both came up to full charge. There does not seem to be any rime or reason why a cell starts to leak or just go dead and stay that way. I bought my first radio in 1964, it was made in Germany and came with twenty four Deac Nicad button cells in various size packs. I still have two cells left and they work fine. About five years ago I purchased a box 24 600 MAH nicads and after three years of use three of them were dead, one from leakage. So I guess the bottom line is regularly check your battery packs and either record or remember their state. I have several battery pack in the garage and they all maintained their full charge voltage over the winter. No matter how old the battery is if it will not hold it's charge for several months, take it apart and check the voltage on each cell.

Re: Nicad Collecting

Nicads can surprise you! About 1988 or so we had a customer come in the shop with an electronic dead weight gauge that had a poor NiCad pack. We ordered him a new one and I took the old one home. It had 2 dead cells but the rest seemed fine. I made glow starters out of 2 of them and used them for many years till they finally quit taking a charge. Last year I pulled the last one out of the drawer, soldered it up and voila! holding a charge just fine! After all these years sitting dead!

Re: Nicad Collecting

You mention that some of your cells seemed to go bad over the winter.

NiCd batteries contain electrolyte which is susceptible to freezing depending on the charge state of the battery. A fully charged NiCd cell is very hardy with a freeze rate somewhere around -70C... but a fully discharged NiCd cell may freeze at -10C.

If your batteries are outside during a cold snap they can be damaged in a few ways and weaker/highly discharged cells may split due to expansion.
