100 amp load is a bit light for testing. Need to be closer to CCA unless the indicator adjusts for this.
I thought I read MEX said these 65s were often acid starved and that may account for the low voltage and specific gravity.
I would just keep running them. Test in 12 months to see if the numbers keep dropping.
For a superior replacement consider Bosch or Odyssey AGM.
I don't have a carbon pile for a load, just the 'toaster' 100amp load.
I would have kept running but for two things; I am getting engine codes and I camp remote. Bad time to have a battery crash on me in the Sierra's in the winter.
