How do I test the loads on my house battery to make sure they are all in good condition. My battery depletion rate seems fast even with minimal draw one light and frig and micro clock on. I see battery load testers on amazon but need more info on how to go about it.

Usually a load test will kill a battery if it's anywhere near bad. You would have to do each one individually. I would think if you isolated each battery and let them sit, you could probably find the culprit by voltage tests on each after a period of time. Load testers basically put a direct short to the battery through a resistor.
 
One simple way to look for a bad batter that may be drawing down the rest, is check with your hand if one of them is much warner than the rest.
