Personally I would invest in a battery monitor (for any system) and do your own load test. Charge them up fully, put a load on them and see how many Amp hours the provide until you get to your low voltage shut off. ~12v rested.

It would be odd for the batteries to be working fine one day and quit the next.

I will plan on doing a load test after our trip to Zion NP next week and get a better feel for life left in the batteries. Thank you for your help and suggestions.
