Those voltages look normal for lead acid batteries. Very similar to mine before swapping out my AGM’s for LiFePO4.
Get an inexpensive wireless thermometer similar to this one to let you know if you need to do something about rising temps.

If nothing else, it will provide some peace of mind about the safety of your food supply.
