Bosch has recently added a new battery tester to its line. The BAT 110 is a rugged battery tester that uses state-of-the-art conductance technology to provide load-free testing of most types of 12V batteries, (including AGM [Absorbant Glass Mat], standard, and maintenance-free batteries) and can test batteries as low as 5.5 volts. The BAT 110 also incorporates a temperature compensation feature to aid in battery test results and requires no internal batteries. As a voltmeter, it has a test range of 5.5V to 19.99V. while the battery cold cranking amp test range is from 200 – 850 CCA (Cold Cranking Amps).
The tester is also capable of diagnosing 12V charging systems and starters. For easy reference, it features a high and low voltage storage function when checking charging systems; and a low voltage storage function when testing starters.
The large, four-digit LED screen displays the voltage and CCA readouts, while the three “stop-light” illuminated LED indicators show the battery’s condition: green = good; yellow = marginal and red = replace.
