Mixing Batteries on Float-- Mex Test Update 2

Looks like we have completed this part of the test:
They seem to have stopped dropping in voltage so quickly.
was 12.72/12.66, then 12.66/12.61, then 12.63/12.59, now 12.62/12.58
Next is the recharge test from 12.6 to 14.4. I will try that on one of them first to see how long it takes, and if any tricks to it using a Vector charger set at 2 amps (does constant 2.2a according to its read-out and it goes to 14.6v). Then I'll know how to do the other one
EDIT--I think Mex left out what starting SOC to use! I was wondering if they would hit 14.4 right off since they are already 'full'
"The one amp (2 or 3 amps is acceptable) recharge kWh test is easy to do. Stop charging when voltage stabilizes at 14.4 then see how many kWh have accumulated."
So I clamped on the charger to Battery B and the voltmeter and watched the time. Charger ran at 1.8 amps steady the whole time.
It took 6 minutes and five seconds to get from 12.58 to 14.40
I let it run and voltage got to 14.62 in another minute and a few secs, then the charger stopped, said FUL
