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...

I thought it pretty strange for a battery that was down to 8 volts, to be reading all the way up to 15.7 in only 15 minutes on a 10 amp charger. After disconnecting the charger and waiting a while, it started the car and still had a resting voltage of 12.7. I tried to start the car again and got the telltale clicking noise. Now the meter says 10.3 volts. Off to replace the battery. Thanks for the feedback!
