unknown current drain on batteries.... December 10, 2013, 04:17:04 pm Yahoo Message Number: 144022Hi Aad. I'm glad that your heater isn't the problem, but what the problem is, might be harder to find. Battery chemistry is definitely affected by temperature. Electricity production slows down at lower temperatures. The voltage will drop more when more current is demanded. A small load such as a ceiling light, medium load like the heater or heavy load like the water pump will cause a cold battery's voltage to drop, and slowly recover. Surface charge on a battery while being charged, or after having been recently charged, will make the voltage appears higher than it really is. So battery voltage alone isn't very useful. After a few days of dry camping in cold weather, I've had anxious moments watching my battery voltage decline at night while running the heater. Solar helps a lot. It is normal for the battery voltage to decline at night, and rise with warming the next morning. That is obscured when the solar kicks in to start charging the battery. As you find out more keep us informed about what you find. The knowledge base here amazing. RonB

As a result I have not paid much attention to it, with the exception of some normal upkeep and servicing, and she has served us well. With my boat restoration behind me and facing a little little problem, my R V enthusiasm is back. I have become an eager learner and student
