Battery check.

[rwleigh]

Just checked my battery again and it seems to be holding up quite well for nearly 5 years old and considering how many people have battery issues with these cars.

Those readings look good particularly the voltage. Had the car been standing for a couple of hours prior to the check? Can make quite a difference to readings if just run.

Been standing about an hour after the last run, looks like it might last a while yet though.

So the best time to test the battery and get a good reading is after it's been standing for a few hours?

Best off checking when been stood for a while to let all the systems power down fully and enter there "sleep" state.

There can be a few systems which can remain active for a while hence giving you a false reading.

Well now I’m even more confused . My stop/start rarely works but my battery voltage says 14V on my OBDeleven after cars been sat for 24h

[clubsport]

14v is a high reading for a battery that has been idle for 24 hours, A 12v battery should show 12.5-12.8v under normal circumstances.
A 14v reading is what you would expect to see with the engine running and a healthy alternator is charging the battery.
I would try another battery to see if it makes a difference.
Or try your Obdeleven in another car to see what reading you get for a different idle battery.

Stop/start seems to have stopped on mine but TBH it's been a while since it's had a good run out. Note to self, get out more!!!!
T'other half's Fiat 500 stop/start is also tempremental, pottering around doesn't charge battery enough for it to initiate. No problems after it's had a good run out.

Just checked my battery again with the OBDeleven and it shows a reading of 11.3v and my stop/start has worked once in 2 or 3 months. I'm going on a long drive Saturday so I'm not sure if that will be a good thing for it or if I should be worried in case it doesn't start when coming back.

Might get a new battery next week for piece of mind? Don't think I can buy Pro activation for the OBD11, get a new, battery, and code it, all on Saturday morning.

Edit// Also, what is a good replacement battery?. It's a weekend car as I have a work van. AGM battery? Is one from Halford ok? Prob one of their own brand ones?. Could pick one of them up off the shelf instantly
