batteries
The noise is more likely coming from your circuit''s VCC line not really the battery itself. With an increasing battery impedance the VCC noise will become more prevalent as it would no longer have the original low impendence path to ground, (through the battery). This is like placing a higher and higher resistor inline with your battery.

6 FAQs about [How to make the battery more current-noisy]
How to reduce power supply noise?
So anything you can do to reduce power supply noise should help. You can also use Smoothing to average-out the readings to reduce noise. Of course, the slope factor has no effect on the (corrected) zero reading (since you are multiplying by zero) and now the readings should be "perfect" at zero and maximum.
How much noise can a battery fan make?
We also determined that the battery fan noise was tonal in character. This meant a tonal noise correction of 5 dBA would need to be applied to the City’s noise limit and therefore a noise limit of 40 dBA would apply at the residences if the tone could not be removed.
Are battery energy storage systems causing noise?
Battery Energy Storage Systems (BESS) are relatively new to the US, and communities are only just starting to become aware of the noise issues they can create. BESS’s are generally large power storage facilities, often comprised of hundreds of battery units the size of shipping containers spread over many acres of land.
Why does a capacitor make a noise?
If you are sensitive to ultra low noise then the actual series resistance of the power source comes into play. A simple resistance can generate noise which is dependent on temperature. At first I would assume that a perfect capacitor would have less resistive noise then a battery that has some value of internal resistance.
Is a switching power supply a source of noise?
The switching power supply itself is also a source of noise. This noise does not only flow through power supply lines as conducted noise but also becomes radiated noise (harmful electromagnetic radiation)—which adversely affects itself and other electronic equipment.
Why does my Arduino make a noise?
Some noise may be getting-in through the power supply. Since you are presumably using the Arduino's default Vcc ADC reference, noise in the reference will result in noisy/unstable readings. Noise in the sensors power supply will also result in noise from it's output. So anything you can do to reduce power supply noise should help.
