About ANCEL
ANCEL is an automotive diagnostics and maintenance-tool brand headquartered in Marietta, Georgia. Founder Mr. Hao began selling automotive diagnostic products in 2013, and the brand officially launched in 2016 with its first device, the AD310 OBD2 scanner -- a product the company says "quickly climbed to the top of the Amazon bestseller list." That claim holds up in RevRated's own data: the AD310 still carries 62,938 reviews at a 4.6-star average, the deepest review base of any OBD2 scanner in our roundup. ANCEL's catalog has since grown to cover professional scan tools, heavy-duty truck scanners, battery testers and chargers, brake maintenance tools, and WiFi inspection cameras, built around a stated mission of keeping car maintenance and repair costs affordable for everyday drivers.
The brand's diagnostic tools have drawn coverage beyond its own storefront -- Tom's Guide included the ANCEL BD310 in its best OBD-II scanners roundup, naming it a "Best dual-purpose" pick for working as both a standalone handheld scanner and a Bluetooth-connected secondary in-cabin display. On RevRated, ANCEL's BA101 battery tester is one of our top picks in car battery testing: it tests conductance, cranking current, and charging-system health across flooded, AGM, GEL, and maintenance-free batteries from 100 to 2000 CCA, covering everything from a Group 35 sedan battery to a dual-battery diesel pickup, backed by a 3-year warranty.

Why we recognized ANCEL
The RevRated Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose products consistently stand out in our hands-on category reviews. ANCEL earned it on the strength of the products below, evaluated the same way every product on this site is: bought, run on real vehicles, and judged on merit.
ANCEL products we rated highly
ANCEL BA101 Professional 12V 100-2000 CCA Battery Load Tester
Tests batteries from 100 to 2000 CCA in a single unit -- covering everything from a Group 35 sedan battery to a dual-battery diesel pickup setup without swapping testers. Built-in cranking and charging system tests diagnose the alternator and starter draw alongside battery health, and the menu walks users through battery type selection (flooded, AGM, GEL, maintenance-free) so test thresholds match the chemistry. Reverse-polarity and short-circuit protection plus thick-gauge clamps make it safe for less experienced users, backed by a 3-year warranty.
