Bringing up a very old thread here.

Today I installed a Braille B3121 battery in my M3. Installation was pretty straightforward; however, I'm having an issue with the voltage. Using the iCarly application I set it as 40AH AGM. My understanding it's 36, but that's the closest option there. I set it, but couldn't register it. No big deal initially, I took it out on a test run with no problems. Then I let it sit for an hour or so, cranked it only to get the "Increased Battery Discharge" error. So I pulled the iCarly app out again tried to verify that it;s showing up as 40AH AGM, then I checked the voltage read out and it was 14.5 volts, which is fine. Does anyone have any idea on getting rid of this increased battery discharge?
