Using a 9V battery instead of a DC power supply
I have a DC power adapter that has the following specs: Input Voltage: 100-240V AC, 50-60Hz, 0.5A Output Voltage: 9V DC, 1.5A I am interested in taking a 9V battery and a snap adapter so I can use my device away from my outlet. However I am not sure how to ensure the output will be 9V DC and 1.5A (specifically the 1.5A).
Charging battery with constant voltage and current, with DC power supply
During this initial phase, the battery undergoes charging in constant current mode. The voltage of the cell gradually rises. Once the voltage reaches 4.2V, the charging mode transitions to constant voltage. Throughout this stage, the current steadily decreases until it approaches zero, indicating that the battery is fully charged.

Optimal Voltage Levels for a Fully Charged 12V Battery
For example, a half-charged battery may read between 13.1V and 13.2V, while a quarter-charged battery may read between 12.8V and 12.9V. It''s also worth noting that a 99% charged battery will read 13.4V, and a 93% charged battery will read 13.3V. A 13.6V reading at rest would indicate a newer, fully charged lithium iron phosphate battery, while ...
Understanding DC Circuit Capacitor Behavior
When the capacitor voltage equals the battery voltage, there is no potential difference, the current stops flowing, and the capacitor is fully charged. If the voltage increases, further migration of electrons from the positive to negative plate results in a greater charge and a higher voltage across the capacitor.
