I'm not sure but I don't think tubular batteries use AGM technology.
I'm using the numbers given by my inverter/charge controller. I also have a circuit that measures the voltage.
I do have another battery but It is quite old and damaged and is not connected to the system.
I never discharge it with higher than 10 amps. Typically less than 5.
This is the charging curve of my inverter/charge controller.
I know 30 amps is above the recommended charging current. But...
The point is, my battery's voltage drop Is higher even with less current and bigger capacity.
I never got the battery below 70% of its capacity. How am I using it aggressively?
The 10.8v is the voltage with the load on. Not a resting voltage.
My inverter has a built in charge controller. I...
I have a 200ah lead acid tubular battery connected to my solar system. I notice the voltage drop is too much for the load I am putting on the battery at night time.
On 10 amps load the battery voltage went down to 11.5 in under 2 hours.
I saw a chart that doesn't match my battery's...
