ANCEL BA101 Plus Car Battery Tester 6V/12V Load Tester — 20–2000 CCA, 2.8" Colour Screen

Designed as an upgrade to the popular BA101, the BA101 Plus expands compatibility to both 6V and 12V lead-acid batteries and adds a full-color TFT display, voltage curve playback and extended memory for service records. It performs battery, cranking and charging system checks rather than just a simple voltage readout, helping you identify weak batteries or alternator issues before they cause a no-start scenario.

How does the BA101 Plus check battery condition?

The tester runs a CCA-based load test and reports internal resistance, state of charge (SOC) and state of health (SOH). Results appear on the 2.8" color screen and you can replay up to 120 seconds of voltage data to watch how the battery behaves under load.

• Measures 20–2000 CCA for regular flooded, AGM flat plate, AGM spiral, GEL and EFB batteries
• Displays CCA, voltage, internal resistance, SOC and SOH
• Playback of voltage curves to show drops during cranking or charging

Can it test the vehicle’s cranking and charging systems?

Yes — the BA101 Plus assesses cranking voltage and scans charging system performance, including ripples and load/unload voltages. That lets you spot alternator problems or abnormal cranking behavior without removing the battery.

• Cranking voltage test to reveal starter or battery stress during engine start
• Charging system check to detect alternator irregularities and ripple voltage
• Load and unloaded voltage measurements for clearer diagnostics

What convenience and safety features does it provide?

The unit includes a single-key Fn quick-test for fast checks, built-in protections and insulated clamps for safer handling. It also stores a large number of records so technicians and DIYers can track battery condition over time.

• Fn one-touch quick test for rapid checks across multiple vehicles
• Reverse polarity, short circuit, overcurrent and overvoltage protection
• Onboard memory for up to 1,400 test records and 120 seconds of voltage replay

Which vehicles and batteries will this tester work with?

The BA101 Plus is made for 6V and 12V lead-acid battery systems found in cars, trucks, motorcycles, ATVs, boats, lawn equipment and small RVs. It is not compatible with lithium, LiFePO4 or 24V systems, so check the battery label for type and rated CCA before testing.

• Compatible with lead-acid types: flooded, AGM (flat & spiral), GEL and EFB
• Designed for 6V and 12V systems only — not for lithium or 24V setups
• Enter battery type and rated CCA for the most accurate results

Who is this for? Mechanics, battery retailers, fleet managers and informed DIYers who need a robust, easy-to-read battery and charging tester that records results for later review. If you service multiple vehicles or want to monitor battery health over time, the BA101 Plus combines expanded battery compatibility, a color display for clearer diagnostics and practical safety features to streamline routine checks.
