The Sealey BT105 is a compact digital device designed for accurately testing 12V automotive batteries, cranking systems, and alternator charging systems. It provides quick and reliable results without generating heat or sparks, minimizing the risk of misdiagnosis. The tester operates without an internal battery, drawing power from the battery being tested, and can test batteries with a residual charge as low as 8V. Results are displayed on an LCD screen and can be printed via PC software.
