My question is simple. Can I use Lm324n while it has been directly connected to different types of batteries? For example series AA batteries Or Use 12V automobile car with 60 Ah.
Here is the datesheet of lm324n

Hi Nana
I don't know if I understand your question.
First of all, I don't know either if you're in the right place to ask that, but I will try to help you.

LM324N has wide power supply range:
– Single Supply 3 V to 32 V
– or Dual Supplies ±1.5 V to ±16 V

So, if you're using a single supply, you can use both kinds of batteries. Even you use a 12V-60 Ah battery, your circuit will consume only the necessary current.
If you're using dual supplies with different batteries, they must be in series in order to have a symmetrical voltage power supply. However, your circuit will also consume only the necessary current from both batteries.

Best regards!
