A great two in one tool perfect for any investigator. This pocket-sized device will not only make sure your batteries are fully charged, but you can also use it to see if any entity nearby is draining your batteries.
How Does it Work?
Simply place your 9Volt battery on the top, or use the red slider to test your AA, AAA, C, D, or button batteries. The digital readout will show you how much power is left in your battery. Note that rechargeable batteries will often show a lower voltage.
You can leave the battery in and observe the front- if the battery drains quickly, it could be a sign of a spirit draining the energy from the battery. The tester itself does not draw energy, so if the battery level is dropping quickly, it could be a spirit.
Features:
Tests AA, AAA, C, D, 9V, and 1.5V button batteries
