how to convert AC device to run on Battery? | All About Circuits
What is important is what comes out of that power supply, I.e., 9V. To run it off a battery, you would not use the AC adapter. You would connect your DC 9V source to a plug identical to the one coming out of the adapter and plug that into the power jack on the tablet. A small 9V battery is not sufficient.

How many volts does a lithium ion battery supply?

How do you charge a lithium battery?
A fully charged Lithium is 4.2V. Just power it from 5V USB, with a standard 1n4001 diode in series to drop a volt. You might need an electrolytic capacitor across the battery place e.g. 1000uF to reduce noise and supply peaks. (batteries have a low impedance, and it has only 3" of wire) Brilliant! Why didn't I think about this?
How many Ma can a lithium ion battery supply?
The size of a battery is specied in terms of the electrical charge it can supply. A Lithium-ion battery of 400mAHr can supply 400mA for one hour. It will supply 200mA for two hours. While 400mA is the rated current for this battery, up to three times the rated current or 1.2A can be drawn for a duration of 20 minutes.
How to avoid loss of efficiency in a lithium ion battery?
To avoid loss in efficiency, we must use larger battery. For lithium-ion battery 400mAHr is considered a unit cell. Using multiple cells in parallel enhances the current capacity and lifetime. Thus, a battery size N means a battery consisting of N unit cells. For example, a battery of size N 5 will be rated at 2AHr.
How does a lithium ion battery charger work?
While the charge current is tapering down, the charger operates in voltage- regulation/constant-voltage phase. The typical regula-tion voltage is 4.2 V for Lithium-Ion (Li-Ion) cells. For fastest charge time, the charger must provide the maximum charge current for which it has been set, until
How do you use Equation 7 in a battery charger?
Equation 7 can be used to determine how low to make the cable resistance and connector (for instance, select a higher quality cable and connector), or how wide/thick to make the PCB trace to avoid excessive voltage drop at the charger’s BUS pin. This maximizes the adapter’s power for charging the battery.
