I have a very similar battery tester. It's FAR better than just hooking up a voltmeter.
SOH = State of Health : that gives a percentage of "life" on the battery.
SOC = State of Charge : an immediate indicator of charge.
MR (or RES) = Internal RESistance or Milli-Ohm Resistance (Depends on the brand) : an indicator of the battery's internal resistance which shows how much is left of the battery. I think the testers use this to extrapolate an SOH reading. It's hard to get an interpretation of what resistance level is good and what is bad because each battery is different.
If anyone has better knowledge of about the resistance levels of a 12v flat-plate AGM, please share.
