Batteries sat for 5 months without charge

I post this for a data point because many on here ask the question about how long a battery can sit without a charge. In Oct I winterized the MH and fully charged the batteries, hit the disconnect switch on the house batteries and removed the negative cable on the chassis battery. Today I checked the voltage readings and the 12v chassis battery read 12.55 v and the 2 6v GC batteries read 12.48 v. That is very little self-discharge for 5 + months. Of course, in cold weather the self-discharge is less.

You were lucky. Batteries appear to have survived. Low self discharge is one Lithium advantage.

My batteries in my hunting rig only get used in September. At the end of Sept they're fully charged, hit the disconnect switch and they're good until next Sept after sitting in the rig as far down as -60F during the winter. The last set of Interstates I changed out after 7 years and I expect to get the same out of this set.
