    Suspicious about my 200ah battery actual capacity

    No I have not. Yes. This is the reading from the inverter. I don't but the temperature is not that high. About 16c°. Thank you for your time sir!

    Suspicious about my 200ah battery actual capacity

    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.

    Suspicious about my 200ah battery actual capacity

    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...

    Suspicious about my 200ah battery actual capacity

    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...

    Suspicious about my 200ah battery actual capacity

    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...
