More on battery
capacity at low discharge rates. As I posted above, comparing my consumed energy in amp hours to the battery
state of charge figure shows the battery
(225 ah C20 rating) has a 280 ah rating at my actual discharge rate.
Last night at bedtime (82 hrs of dry camping) I had used 141 ah and soc was 49.8%. I shut everything off, including the refrigerator
. This morning, ten hours later, the battery voltage was 12.02. Trojans resting voltage vs soc chart indicates I have 44%. Trojan says to remove all loads before test at least six hrs but preferable 24 hrs. I waited ten hrs. I also did not disconnect the batteries. While everything was turned off there are still very small phantom loads from inverter, charger and battery monitor. With this said, I think the voltage measurement supports the meter reading of 50% soc even though 141 ah had been drawn from the battery.
Has anyone else measured results like this?
