I have a 100A lead acid deep cycle battery and also have a car's 12V 100A charger (alternator with AVR)
At 1500RPM the alternator will produce nearly 100A.. and the battery is directly connected to the battery, will the 100A be pushed into the battery? Or will the battery act as a load and take only what it needs? And how can I calculate the battery's resistance? I don't have the datasheet nor know the brand (unbranded).
I have been searching on the internet and they all just talk about the relation of the batteries resistance to its capacity.. nothing about how to measure it nor about the charging capabilities... (Can I get a reference on how to measure it please?)
So, is it safe to connect it directly? (The built-in AVR cuts of when fully charged) or do I need a limiter in between?
