Was pleasantly surprised by the batteries you can check. Sebst uncommon Photo batteries and lithium button cells get tested. The display shows not got a voltage at, but as a first check for batteries fully in order. Check out one battery (AA or AAA) shows the tester due to the low voltage 1.2V only an average charge, even though the cell is already fully charged. A Volt would help us. Otherwise, the device is also recommended because of the small price quite!
