Universal Battery Tester

Features of our Battery Tester include: Able to test AAA, AA, C, D, 9V & button cell batteries.  Easy-to-read, color-coded reading meter: Red range = Replace, Yellow range = Low Power, Green range = Good.  Dimensions (inches): 4-1/2” x 2-1/2”.  
Plastic body in black.  Sliding red contact for manual adjustments.  

While testing 1.5V & 9V batteries, get the reading from the top scale. While testing button cell batteries, get the reading from the lower scale. If the needle does not move, check and make sure the battery is touching both contacts before assuming it is completely dead. This battery tester is very easy to use and does not require batteries to operate.
