Inspired by Victors question about NiZn battery numbers, I'm looking at some stuff I've saved.
The % capacity curve with a flat line up to perhaps a .7C discharge rate (hard to swallow) with an unexplained point of inflection and a non linear-non logarithmic current scale. While curves with this many odd things about them can be produced by an honest person, an Engineer shouldn't let them get out. Same curve in an SAE paper without explanation and the PbA (not PbLA) curve is an abuse even for marketing. Then, there is the M40 cell .pdf curves. A plot of average voltage. Is this a BCI specification ? Average of what. I think it does mean something. A curve of discharge Ahr capacity, essentially flat, vs. discharge rate. This might be something the battery Can do, but there has to be a resulting acceptable Voltage drop which is scary. No mention of heat boundaries. Perhaps after a cautious break in, the batteries will take really high current, but they must be getting hot A set of Volts vs. Ahr discharge curves that fall into two characteristic patterns or 'sets' between C and 2C. Again, no explanation. I think these things might be great, but these presentations are shaky. There is very definitely a Peukert curve since it is defined as using a fixed end voltage (right or wrong) The 4 second Sheer test puts the resistance between .0037 and .0056 ohms. Not sure exactly which battery ______________________________________________________________________
