I have 2 x Royal 1150K 105ah 12v lead acid batteries in parallel hooked up to a Mecer 1200VA inverter.
On that I'm running a mini PC and monitor that draw an average of 70W
If I do the math:
105ah * 2 @12v = 2520Wh
Assume 80% conversion efficiency = 2016Wh
50% depth of discharge = ~1000Wh
1000Wh / 70W draw = 14 hours
Is that right? I'm getting less than 2 hours before the inverter tells me the batteries are at 50%.
What am I missing? Are the batteries just fubar?
