TDR Rag...10.5V = no start?

OK, I've been having an intermittent bucking start...think I figured out why. I read the TDR rag last night and they made the statement that anything below 10.5V is a no start for a CRD.

I turned on my GPS this AM (unfortunately, after the grid heaters cycled) and hit the starter...voltage dropped to just around 10.5V. Which at 30*F, the voltage should not have dropped that far, that fast, which leads me to believe I have a battery with a bad cell that is probably causing my hard/bucking start issue. And to add, voltage started around 12.5Vs, and almost instantly dropped to 10.5V...it didn't slowly drop, it fell! The starter still spins fairly normal...

So short of actually getting the batteries tested, this is probably my issue. I'm going to get a multimeter out tonight and see what happens in the AM...probably going to need new batteries. Last truck I had, my 99, got traded at 200k with original batteries (and those had a lot of abuse)...these are what, a little shy of 4 years old with 142k and bad??
