Does this work for rechargeable Ni-MH batteries?
Yes! While the scale is calibrated for standard 1.5V alkaline batteries, it effectively shows the charge level of 1.2V Ni-MH rechargeable batteries as well.
Where do I place the 9V battery for testing?
There are two dedicated contact points located at the top of the unit labeled for 9V batteries. Simply touch the battery terminals to these plates to get an instant reading.
How do I test small button cells?
Place the button cell between the sliding arm and the stationary contact. The adjustable arm will hold it in place while the analog needle indicates the power level.
