BAT 110 battery tester

The Bosch BAT 110 battery tester uses conductance technology to provide quick and accurate, load-free testing of most types of 12V batteries, (including AGM, standard, and maintenance-free batteries) and can test batteries as low as 5.5 volts. The BAT 110 incorporates a temperature compensation feature to aid in battery test results and requires no internal batteries, using the test battery for power. As a voltmeter, the BAT 110 has a test range of 5.5V to 19.99V. The battery cold cranking amp test range is from 200 CCA to 850 CCA.
