## BMV 712 and SOC State

Hello,

I have a BMV 712 and I do not fully understand the SOC State. I have setup a 260 AH AGM battery within the BMV 712 setup. Once the battery is fully charged and my solar page do not create any power the used amps begin to count since the power of the battery is now used. So far nothing special.

BUT if now 5,2AH are used the SOC State is displaying 99.0 percent. But if from my understanding using 5.2 AH from a 260 AH battery would result in a SOC State of 98.0 percent. Therefore the SOC percentage seems to be wrong.

What I am missing in this case? Any feedback would be much appreciated. Thank you!

This is not a simple plus minus divide question. A battery is a highly non linear thing. Simple answer is the more slower you discharge the more capacity the battery has.
