OBD11 or OBD11 Pro ?

I was probably out there with it plugged in for 5 min. What I plan to do is test it straight after I drive it next instead of parked on my drive. Either way, I assume 11.5v is not normal and too low?

Yes, I believe that's much lower than what you want

5 minutes will be fine

yeah, too low. Mine won't start if it's that low

Just went out today 15 min drive there and 15 min back. Checked on the drive when I got back and voltage on the app said 13.4V this time.

Despite that, the stop/start didn't kick in once but bout 6 months ago when I used to make the same drive it would kick in about half or three quarters of the way there or back

Edit// Also my car did this weird again for the 3rd time which I've mentioned on here before. When I reverse, stop, and put the car in neutral, the car turns the engine off and then it doesn't come back on when I press the clutch in. The screen says to turn the key to get the engine back on. Maybe related to the potentially dodgy battery messing with the stop/start?. But then why would the stop/start only work after reversing and then not restart the engine?. I'm so confused

I would say your battery is on its way out.
Mine has not worked for a similar amount of time, even when having just come off the charger and being fully charged.
The battery monitor seems to be quite complex and as it is sensing that the battery is not 100% it disables the S/S, a billy bonus some would say!
