That can also be an artifact of the way battery charge level is calculated by the computer.

Think of pink fiberglass insulation, but squished a bit to make them somewhat stiff (but not rigid). Some call AGM (Absorbed Glass Mat) batteries by the name "Fleece" batteries, the fiberglass sheets look like wool fleece.

That indicates a broken electrical connection inside the battery, either between cells or from cell to terminal. Usually caused by mishandling. The connection can handle the microamps of the voltmeter, but not the milliamps (or more0 of a real load.
