Product Overview
I recently had the opportunity to test out the ANCEL BA101 Professional 12V 100 2000 CCA 220AH Automotive Load Battery Tester. After spending some time with it I was very impressed with the construction and features that it offers.
The BA101 is a small, compact device that quickly and accurately tests a 12 volt battery. It provides an extensive range of tests, including voltage, charge, starting power and remaining battery life ohmic resistance level . It is also compliant with JIS, EN, DIN, SAE, CCA, BCI, GB, CA, MCA and IEC standards so you can be sure it is providing accurate readings.
The device also has a large LCD display with white backlighting and adjustable contrast which makes it easy to read the test results. The buttons are intuitively placed for easy use and there are no internal batteries required as power is drawn directly from the 12V battery. The cable that comes included with the tester is 3 feet long and made of thick flexible insulator which makes it safer than some other devices on the market.

I found this tester to be incredibly useful for testing the charging status of my cars alternator and starter as well as the vehicle s charging system including load voltage, unloaded voltage, ripple status and charging system status. It has saved me time when diagnosing issues in my car s electrical system.
Overall I would highly recommend this device to anyone looking for an efficient way to diagnose their car s electrical system. The BA101 is easy to use even for beginners and provides accurate readings across a wide range of tests. Additionally it is well built and safe due to its thick insulated cable. I would definitely recommend this product to anyone looking to maintain their vehicle s electrical system or diagnose any issues they may have.
