You are talking of a situation such as a shorted out battery. If the wire (or whatever you use to make the short circuit), has zero resistance, then placing a volt meter across the battery terminals will show no voltage, although a current flows through the wire.
Load Tester: Applies a load to the battery and measures its performance under stress. Testing a battery involves several steps: Step 1: Check the Voltage: Measure the battery’s voltage using a multimeter. Step 2: Test Under Load: For a more accurate assessment, measure the voltage under load (i.e., while the battery is powering something).
If the current flows in that direction, the battery is discharging. If the current flows in the other direction, the battery is charging. It is a little bit like a spring or a clockwork toy. When you have a spring, it tries to push in a particular direction (longer or shorter). If the spring moves in that direction, then it's discharging.
If the battery is not connected to anything, the voltage between its poles exactly matches the electro-chemical potential of the reaction. The placement of the voltmeter changes the thing you are trying to measure. Yes. Without the voltmeter, there's no voltage-drop between the poles, because there's no closed circuit. This is mistaken.
Be aware of the environment: Avoid testing batteries in wet or highly humid conditions. In wrapping up, it’s clear that a battery can have voltage without significant amperage. This phenomenon often signals issues like high internal resistance or battery wear.
When the battery is being drained by a circuit, the voltage is a little lower, allowing reactions to proceed. The higher the drain, the lower the voltage, the faster the chemical reactions, and the greater the current. That effect creates what we can measure as the battery's internal resistance.
No battery detected with adapter plugged in
Hi @louie77,. Try the following: Go to Device Manager >Battery > right-click ACPI compliant entry > uninstall then restart the laptop and check.. If it still shows as not detected, create a Win 10 battery report and check what it says.. If still not there open the laptop and check the connections again. I know you said that you double-checked before closing but….

There would be no EMF (electro-motive force) to generate a current to boot the chemical reaction in the battery. "If a battery is in the forest, and there is nobody around to measure it, does it have a voltage?" The electro-chemical reactions inside the battery happen only when there''s a closed circuit. For an ideal battery, this is true.

Why is there no current flowing across the battery
The battery is like a pump. It literally forces water from one side to the other, and allows no water to flow the opposite way. A battery is a fairly complex electrochemical device, but it does indeed act as a one-way charge mover, which via high chemical potentials separate electrons from atoms at one terminal and reunites them at the other.
