I'm not well versed in Lead Acid/AGM batteries. I bought a Noco Genius1 charger/maintainer as I saw voltage was low in my M40i (11.4). It charged overnight and was full by morning.
I was showing a healthy voltage on the GT at 12.8 but I figured I'd throw the Noco at it since I've seen several other GTs already indicated their 12v was either dead on delivery or has died shortly after.
It's charged overnight and it's still charging this morning. I suspect it was relatively low in charge. So if the HVB maintains the 12v...what's the difference between maintaining and charging?
Were 12v's not charged before installed? Were they just drained during transport? Does the "maintenance" the car does with the 12v not increase the state of charge of the 12v? Help me understand if you do please.
edit: Just finished charging so roughly 13-14 hours of charging at 1amp....so assuming 13-14ah and the battery is 35ah so I'm estimating that would mean the battery was at roughly 60% state of charge.
Yikes.
