12V Battery and OTA updates

[Milo Minderbinder]

Hey everyone, I'm trying to figure out the best way to keep my 12V battery topped off for those pesky OTA updates. I've been going on little "battery boost" drives to keep it around 80%, but that's a pain. Anyone know the ideal 12V SOC for updates? Also, will leaving my car running in the garage with the L2 charger plugged in fully charge both the 12V and the main battery?

I'd charge 80% or more for installation. However, if your battery's capacity is depleted, 80% may not be enough. The exact threshold varies according to the battery's age and condition.
