How long should a battery last?
Typical code 24 battery, how long should it last with lights and electric RV fridge? I am only getting about 24 hours before it gets under 11.5V. Also, would a battery shop have a way to properly test...

For two days I would just freeze ice jugs and put several in the freezer section and several in the refer section. You start with fully charged batteries frozen jugs, and cold food, while driving you are powering your refer from the alternator. Once the ice jugs melts after several days use the ones in the freezer section. If you use your battery power just for water pump and a few lights you should be fine for several days. When it comes time to replace the battery, replace it with 2 GC batteries wired in series and you will last a week and still be at 50% plus SOC, with your electric refer off.
