ANCEL Car Battery Tester BA101 Plus 6V/12V Load Tester — 20–2000 CCA, 2.8-inch Color Screen

The BA101 Plus builds on ANCEL's BA101 line with upgraded compatibility for both 6V and 12V lead-acid batteries and a clearer 2.8-inch color screen. It runs comprehensive battery, cranking and charging system checks, records up to 1,400 tests, and replays voltage curves so you can spot drops during cranking or charging. Rugged insulated clips and built-in protections make it practical for DIYers, mobile technicians and shop environments.

How does the BA101 Plus check battery health and what readings will I see?

The tester evaluates battery condition using multiple electrical measurements rather than only open-circuit voltage. Results report CCA performance, voltage, internal resistance, state of health (SOH) and state of charge (SOC) to give a fuller picture of battery capability.

• Load test range: 20–2000 CCA for common lead-acid batteries.
• Displays CCA, voltage, internal resistance, SOH and SOC values.
• Supports Regular Flooded, AGM (flat/spiral), GEL and EFB types.

Can it diagnose starting and charging system problems?

Yes — the BA101 Plus runs cranking and charging checks to reveal starter draw issues or alternator charging faults. It captures load and unload voltages plus ripple voltage so you can detect abnormal alternator behavior or excessive voltage drop during cranking.

• Cranking test with voltage curve replay to find transient drops.
• Charging system check including ripple and charge voltage stability.
• Records 120 seconds of real-time curves for review and diagnosis.

What makes the BA101 Plus easier to use in a shop or garage?

The 2.8-inch color TFT screen improves readability under varied light and the Fn one-touch key runs a quick test without navigating menus. Durable insulated clamps and onboard safety protections reduce user errors while storing large numbers of test records helps track battery performance over time.

• 2.8" color display with clear numeric readouts and curve replay.
• Fn one-touch quick test for fast checks across multiple vehicles.
• Storage for up to 1,400 records for trend comparison and fleet use.

Which batteries and vehicles are compatible with this tester?

The BA101 Plus is designed for 6V and 12V lead-acid battery systems found on cars, motorcycles, trucks, boats and many powersports vehicles. It is not compatible with lithium, LiFePO4, or 24V systems, so always set the correct battery type and rated CCA from the battery label before testing.

• Compatible: 6V and 12V lead-acid — Regular, AGM, GEL, EFB.
• Not compatible: lithium, LiFePO4, 24V battery systems.
• Works with cars, SUVs, trucks, motorcycles, ATVs, boats, RVs and mowers.

Who is this for? The ANCEL BA101 Plus is aimed at DIY mechanics, mobile testers, battery counters and small workshops that need a compact, reliable load tester with clear visual data and record-keeping. If you regularly diagnose starting or charging complaints, check batteries on multiple vehicles, or want to compare battery condition over time, this unit provides practical test detail without requiring bench equipment. For users who need printed reports, ANCEL provides a dedicated PC driver and print software; Windows Defender may flag the installer briefly — allow the program to run to enable printing. Remember to confirm battery type and rated CCA on the cell label before testing to ensure accurate results.
