Ancel BST100 12V Battery Tester

Features and Functionality
The Ancel BST100 delivers fast, accurate diagnostics for 12 V lead‑acid batteries. Powered directly by the battery (no internal batteries needed), it uses a high‑precision amplifier and STM‑32 chipset hardware for smooth operation and delivers results in approximately 2 seconds with up to 99.7% accuracy.

It performs a wide range of tests:

  • Battery Capacity (CCA, DIN, EN, IEC, BCI, CA, MCA, SAE, JIS, GB)

  • Internal resistance (Ω)

  • State of Health (percentage) and state evaluation (Good/OK/Attention/Replace)

  • Cranking (load) test

  • Charging system and ripple test

Supports testing of batteries on or off the vehicle, even when charged down, and protects against reverse polarity, over‑voltage, and loose connections.

It supports a wide battery range: CCA 100–2000, 3–220 Ah, and works with most 12 V lead‑acid types—flooded, AGM (flat‑plate or spiral), EFB, GEL, VRLA, sealed maintenance‑free, deep cycle, starting, and marine batteries.

Additional Details

  • Supported vehicle types: Cars, light trucks, SUVs, motorcycles, boats, marine applications.

  • Languages: English, French, German, Russian, Spanish, Italian, Portuguese (varies slightly by source).

  • Safety Standards: Meets IEC/EN61010‑1, double‑insulated, CAT III 600 V / Pollution Degree 2.
