I have an Optima Yellow Top D31 and I do some voltage drop vs the current draw tests. Many peoples say that its not the best but great street battery. I'm disapointed by the numbers that I obtain. Someone have this battery and have numbers to compare with my results?

My numbers:

235 amps: 12.2 volts
350 amps: 11.5 volts
435 amps: 11.3 volts
525 amps: 10.9 volts
750 amps: 9.9 volts
950 amps: 9.6 volts

hmmm..... from 9.9 volts to 9.6 volts u´ve gained 200 amps. Thats a little bit strange. I would assume that u get about 900 amps at 10 volts with a d31 in a good condition.
