So, unless your Arduino board is randomly and continuously switching between 5mA consumption to 1A, there is no reason to worry about this. You can measure voltage battery with voltage reference. You need voltage reference with lower reference than you expect on battery (for example 1.235 V). Then you measure this voltage with your ADC.
A: Monitoring battery voltage is crucial for battery-powered projects because it allows you to keep track of the battery’s state of charge. By monitoring the voltage, you can determine when the battery is running low and needs to be recharged or replaced. This helps prevent unexpected shutdowns and ensures the reliability of your project.
For example if you measure 300 with your ADC and your reference voltage Vr is 1.235 V then your battery voltage Vb is 4.2 V. Another similar, but more complex way is to use voltage divider on battery and use internal voltage of arduino for ADC reference.
The traditional method of battery voltage detection is usually through a power supply voltage divider and sampling through the ADC to achieve detection. The voltage divider detection solution needs extra external circuits, which increases the system cost, volume and power consumption.
This is achieved by running a load and measuring its current while observing voltage drop. Resistance Testing: This testing method involves the use of an ohmmeter, a type of multimeter, to measure the electrical resistance within the battery. A battery's resistance should ideally be very low, close to zero, between 20 and 50 mOhms.

RMS Voltage Peak-to-peak voltage and RMS voltage are both important measures for describing the magnitude of an AC circuit, but they also have some distinct differences, which are listed in the following table: Feature Peak-to-Peak voltage RMS voltage Sine wave expression Vpp = 2 × Vp Vrms = V0/√2 Power relation Inversely …
In this case, the unknown current (I) is equal to 800 watts / 12 V = 66.7 amps. But why would you need to know this? When you ensure proper wire size for safety purposes or want to know what size inverter you may need, being able to factor in Voltage, Current and Power and do basic calculations will help you tremendously.
Discharge testing measures battery capacity by determining how long the battery can supply a constant load until it reaches a specific cutoff voltage.
