12v battery level

[kort]

I have been told that the 12v battery should be at 13.4 my car is at 13. and today it went to 13.7 before returning to 13.5
should I be concerned?

Hardly. It will vary depending on the draw you are pulling from it due to demand, if it is charging from the HV battery, and probably even the temperature of the battery from being parked vs driving.

Sounds fine. Lithium has a very flat discharge profile compared to lead:

No sweat. 13.5 is what to shoot for (pre uPdate 13.4).

that is the answer I was looking for, since the update I've been at 13.5 and sometimes higher, pre update it rarely if ever fluctuated.

Why is it still called "the 12-volt battery" at this stage? Wouldn't the 13-volt battery be more appropriate !!

I guess there's some Irishness to it ?
