I've just recently bought some brand new 2850 mah NIMH for my camera that charge the same way as all my NIMH do. They won't get a full charge unless I charge at .3mah maximum. I can put almost 3500ma into them at a low .3mah charge rate before the charger goes to trickle. Floyd

Re: Newby RX Battery Question

I just checked my battery drawer and there is still three cells from 24 cells that came with my used German radio in 1964 they still work fine. Over the past five years I have thrown out a coffee can full of NICAD and NMHi batteries that quit working or started to leak. Age does not seem to be a factor in a cell going dead. NMHi batteries should be charged at 1/15th to 1/20th of their capacity until they get warm. Full charge on a NMHi pack should produce 1.36V to 1.38V per cell. Like I said before the voltage comes up really fast but the capacity takes a long time to fill. Check the voltage and record it then put it on the shelf for a month. Plug it into your aircraft or what ever and operate it for twenty minutes. if one cell goes down to less than 1.1V or the voltage drops of quite rapidly, do not use it. I have replaced many cells in both receiver and transmitter packs. I just went through about twenty pack that I had not been charged since last January.

Re: Newby RX Battery Question

I tend to agree with others here...if you are buying a new battery anyway, get a Life battery. They are better in every aspect, and depending on your source they don't have to cost more. Also, if you are concerned about voltage, keep in mind the 6.6v you will get from a Life is less than a freshly charged 6v NiMH.
