I have a solar charging I am using with my car battery.
The current voltage of the battery is 12.7 volts.
And the charger is still charging.
Here are some specs for the charger.
Rated power output = 5W Operating power voltage = 18V Operating power current = .33A Trickle charging current = .2A Floating charging Voltage = 13.8 Overcharge Protection Voltage = 14.1 Voltage
At what battery voltage will my solar charging stop?
Thanks, Andy
With those currents probably by 2055.
Do you mean 20.55 volts?
Wouldn't that be a little overcharged?
Andy
I think you know its the year. More accurately, never.
Your answer was of no help.
And it was flippant as well.
Andy
I'm sorry it was of no help but it was true. At that charge rate you would be lucky to stay ahead of self discharge.
I guess you did not factor in my alternator.
Andy
Really? Grow up.
If your alternator is involved that little solar charger will make no difference at all. The smallest car alternator is going to be several hundred watts.
Alternators typically charge batteries at around 14.5 volts, so when the alternator is running the solar charger will cut off.

For a "12V"lead-acid battery, nominal full charge is 13.8V (2.3V per cell)
Nah. 5 minutes to 9.
