I have a 12 volt 36 Amp Hour battery (AGM) If I pull a constant 9 Amps, I should be able to pull that current for 4 hours before the battery reaches a discharge depth of 50 percent (12.3 Volts)? And if I am doing amp hour testing, should I use a smaller current and increase the duration say....4.5 amps for 8 hours? What is the standard for loading when doing A/H testing? Thanks folks.
