Review: Simple to use, detailed feedback on health of batteries. Printer makes it easier to record results - Pretty awesome tester. I use mine on my Off-Grid solar system. 6 volt AGM batteries and have 24 of them with 3 parallel of 8 in series. The tester gives good detailed data from CCA, internal resistance, voltage, state of health and state of charge. The internal printer is especially helpful considering how many batteries I test at once and not needing to write down each reading. Validated the results against my megger and results matched, I had one failed battery (cell) and 3 others nearing the end of life or "weak". I haven't used it to test an alternator since my needs are less for automotive but works great and appears to be accurate. ## Features - UPGRADE TO TRUE PRO TESTING - Step up from the trusted FOXWELL BT705 car battery tester to the BT780 with 6V SOH/SOC testing, 12V/24V cranking & charging diagnostics, a built-in printer & custom shop/technician names.
