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 system).
As a rule of thumb, the minimum amps required to charge a 12v battery is 10% of its full capacity but the ideal charging current should be between 20-25% of the battery's capacity For example. if you have a 12v 100Ah battery then you'll need a minimum of 10 amps and a maximum of 20-25 amps to recharge your battery
If you have a 12V 200Ah battery, the maximum charge current is as follows: 200Ah * 0.5C = 100 Amps Now if you have a 48V 100Ah battery (5kw server rack) the charge current is the following: 100Ah * 0.5C = 50 Amps We can see that the maximum recommended charge current depends on the battery capacity (Ah), not the voltage.
Charge a 12V car battery from the “main battery”. <=> Assumed here the main battery is the battery connected to the car starter engine and alternator. Use of thin cables, to not draw to much power in case “aux” battery is empty. Here is a problem, as thin cables should not be used to present a high resistance to limit the current.
This is why a battery charger can operate at 14-15 volts during the bulk-charge phase of the charge cycle When your battery is below 80% charged it will safely accept the higher voltage (read the spec of your battery to figure out the maximum voltage) and maximum current (Which should not be 20% of the total capacity of your battery)
If we take a standard 100Ah 3.2V EVE Lithium cell (we need 4 of these to make a 12V battery). We can see it has the following specifications: As we can see, the standard charge/discharge current is 0.5C. Now, what is C? C stands for C-rate. To know more about C-rate, I recommend watching my video about it.
