they might be bad i was getting 13.4 out of my batteries with 75k on them. did you do a load test on them? they may be show good volts but fall off after a load test this is common
When you check your batteries, you have to disconnect one and check the other, and then vice versa. The fact that your voltage is under 12 tells me bad batteries, one is prob completely dead and is draining the other. Remmember to change both batteries at the same time. Unlikely, but it could also be a bad alternator. Good luck
