Sign of Things to Come?
I've been watching these batteries for a few days now and have some observations I'm hoping someone has some insight on.
1) During the day, I'll run the gen for an hour. The batteries will get in the high 12.7's, even an occasional 12.8.They sit for an hour and lose .1v or more doing almost nothing but running the onboard stuff.
2) They'll drop into the 12.4's and stay pretty much in that range for the rest of the day.
3) They seem to pick up .02 or .03v during the night.
Questions:
1) Is there a problem brewing with the batteries to lose that much juice in such a short period of time?
Why, when doing nothing, do they lose that much voltage, yet at night when doing almost the same thing, they gain .02 or .03 volts?
I know .02 and .03 is like splitting hairs but I'm trying to understand the observations more than the numbers. The numbers contribute to the reason for asking the questions.
