 The `rated_capacity_Ah` input comes from the settings register set parsed into `contentByteArrayByReadSet`. The app also has a separate read of register `0x0064` length `1` that stores `residueTime`, but the visible live time calculation above is derived from SOC/current/capacity unless current is zero.

+In the BullTron system screen, rated capacity is settings word `0` scaled by
+`0.1 Ah`. The charge and discharge MOS controls write single registers
+`0x00A5` and `0x00A6`; live MOS status is read separately from telemetry
+registers `0x0035` and `0x0036`.
