Eine erstaunlich einfache wie gute Methode wie man Batterie auf ihre Tauglichkeit testet, erklärt der Elektrotechniker Lee Hite in einem YouTube-Video. In Zukunft brauchen wir nicht mehr mühsame Batterietester benutzen. Man lässt sie einfach fallen. Laut Hite springen olle Batterien nämlich nach dem Fall nach. Frische Batterien haben eindeutig weniger Rebound. Diese Testmethode soll sich zudem für alle Batterien eignen. Wieso das so ist? Da wir keine Fachleute sind, lassen wir lieber den Experten selber zu Wort kommen:
A non-rechargeable alkaline battery begins life using zinc powder mixed into a gel containing a potassium hydroxide electrolyte separated from a paste of manganese dioxide powder mixed with carbon powder using a porous membrane. To minimize hydrogen outgassing an extra measure of manganese dioxide is added. As the battery discharges manganese dioxide powder changes to manganese oxide causing the powdered granules to bond both chemically and physically. This packed-sand consistency reduces the antibounce effect exhibited by the gel mixture when the battery was fully charged.
