Over rated batteries?
I wonder how many battery distributors are overly optimistic when rating the capacity of their batteries. I have formed and tested several batteries lately and found that the best performance seems to be about 70% or rated capacity for NIMH batteries. I checked six batteries from two different distributors and found they all fell far short of the 2500 MAH rating. All of these batteries are the AA size NIMH and I suspect that the best one can expect from good quality AA size NIMH is a Maximum of 2000 MAH capacity. I am using good equipment to form and test the batteries and have borrowed other equipment from friends to compare with the same results. However, I did find that one 500 MAH battery that I have had for several years was actually under rated and tested at almost 600 MAH capacity. Are over rated claims typical for RC battery suppliers? Are there industry and/or government standards for NIMH battery ratings?
Thanks for your input.
Best wishes, good luck and good flying.
