OverviewTesting and chargingHistoryPP3 connectorsTechnical specificationsLithiumSee alsoExternal links
Battery chargers are devices that charge batteries, some of which may also be able to charge nine-volt batteries. Whether a charger can charge the battery depends largely on the dimensions of the battery and internal chemistry (I.E., disposable batteries cannot be charged). Testing a nine-volt battery can be done using a multi-meter by probing the voltage across the two terminals. The voltage measured by the multi-meter can then be used to roughly assess the cha…
