Ha
I have connected two batteries in series. The first one is 12v / 7AH and fully charged. The second one is 4 volt/1.2AH and it is 10% charged - almost not charged.
I have two questions.
First, what is the max current I can obtain and what's the AH?
Second, how can I know the age of a battery in general. I have heard that I can measure the voltage while the display is on DC current. I tried that but does not understand the readings.
Regards
