Charging a 12V battery. Isn''t 15V too high? : r ...
I''m testing a 12V solar battery charging system right now! The charger puts out about 14.8V to charge a 12V battery during the day at peak (around 1pm). At night time, the battery is at about 12.8-13.1V fully charged. I disconnected the solar panel last week and the voltage has been steadily declining to 12.4V so far (I''m trying to see how long a full battery charge will last for this …
