Charging car battery, how high v is too high?
Not specifically an RV issue, but... Our two year old car wouldn't start today. A quick check of the battery showed just over 8 volts. I connected a Harbor Freight 2/10/50 charger on the 10 amp set...

There are some that should get educated on hi voltages damaging electronics.
16+ volts is normal for most todays smart chargers. Even my Schumacher 1.5 amp maintainers go over 15 volts in the first stage. And I've seen 16.4 on my bigger Schumacher, on a new battery, when full charged.
And I believe my PD9245 goes well into 15 volts, but I'm never there when it does that "equalize" thing.
I have been told that my batteries will be junk in 6 months. :)
four 6 volts from 12.25 to full in 4 hr 10 min
