Purpose of battery tests – test results below in alphabetical order.
Battery test: a real sensor? With these battery tests, we mainly want to ensure that the products we sell are original and have the same performance as given capacity values. We will later also try to include the tests of the largest continuous current, but at this point we rely on the extensive tests mooch has carried out. If the test results we have received have differed a lot from the values indicated by the manufacturer, we have repeated the test 1-2 times, but very rarely the result changes from the previous one.
Why are the measured capacity values lower than those specified by the manufacturer?
Since the battery test can be carried out in many different ways and the result depends on the depth of discharge (final voltage), the level of discharge voltage, contacts, etc. – manufacturers naturally want to show the highest possible values. Since all batteries are charged with the same charger, tested with the same device with the same discharge settings, the battery tests are comparable to each other and give a true picture of the battery performance compared to other batteries we test.
