Battery Issue
Posted: Sat Jan 09, 2021 2:49 pm
I have the AA CarGenie device connected to the OBD2 port on my 2019 Qashqai 1.3-DIG Acenta Premium which sends driver rating information to an app on my Android phone.
All is well, with my Eco Score stats being around about 90% for speed, braking, acceleration and idling. The only bugbear is that after a short journey, I regularly get a text alert saying that Power has dropped and needs charging. Drive for 30 minutes to restore charge or connect to a suitable battery charger.
The AA even called me to say that they were seeing all the alerts and could they help?
The problem is that I only get one alert for each trip and it doesn't happen if I do a longer trip (difficult in lockdown) or charge the battery. When I check the battery immediately after I receive the alert, it shows no problems and is healthy with a charge greater than 11.5 volts.
Is it possible that on switching the car off after a journey, the voltage will drop below a threshold for a short time and then recover to have a charge over 11.5 volts?
The vehicle was first registered March 2019 and has now done just 10700 miles.
Any suggestions would be much appreciated.
Cheers, Richard
