Getting the following reason why I cannot change the value: -No communication with IBS or engine electronics. -DME/DDE program status cannot save battery change. -Terminal 15 was not switched on. -Engine running.

What size battery does a BMW E90 use? Most US Market E90 use the 90/720 AH/CCA battery. If you have CIC or the business radio with Bluetooth, you car uses the 90/720 battery. It also will have the battery monitor terminal on the negative cable. The “810” part number is the current 90/720 BMW battery.
No. You need to check the battery voltage with the engine off and with the engine running. If the low battery warning remains on while the engine is running this may indicate a problem with the charging system. With the engine off, a fully charged battery should have ~12.5 volts DC.

The drained battery might have been my fault, or might not have been my fault. The Honda parts guy didn't ask. With the proration credit from the old battery, the new Honda replacement cost $38 and change, including tax. It did not require battery registration.
