Marked measurement category

Not recorded

The record has no confirmed CAT category and voltage pair. A marking in a photograph cannot fill that gap.

The buying trap. Confirm the exact model’s manual before considering it for mains measurements.

Related models and generations

These are different products. Check their specifications separately.

  • BT100 (base model) Model: BT100

    The older 12 V 100-1100 CCA analyzer with a simpler display; Foxwell lists a separate manual for it.

    Only when specifically seeking the older model.

  • BT705 / BT780 Model: BT705

    Step-up Foxwell analyzers that add cranking and charging-system analysis.

    DIYers who also want to check the starter and alternator.

Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • BT100 and BT100 Pro are different models; the Pro is the current one with the full result screen.
  • The BT100 Pro does not test 6 V or 24 V batteries and performs no load test, despite being listed on Foxwell's site under the phrase Battery Load Tester.
  • It tests the battery only; for cranking and charging-system checks, that is the BT705 or BT780.

Why people pick it

  • Covers 12 V batteries from 100 to 1100 CCA across eight rating standards, so it can be matched to almost any passenger-car battery
  • Shows numbers and a plain verdict (for example Charge & Retest or Bad Cell-Replace), not just colored LEDs
  • Tests the battery in place, with reverse-connection and overvoltage protection and automatic temperature compensation per Foxwell
  • Pocket-sized, menu-driven and multilingual, and it works fully offline with no app or pairing

Know before you buy

  • 12 V lead-acid only: Foxwell states it will not test 6 V or 24 V batteries and will not load test or deep cycle test
  • Tops out at 1100 CCA, so large truck and commercial batteries above that rating are out of range
  • Checks battery health and state of charge only; unlike Foxwell's BT705 and BT780 it does not analyze the vehicle's cranking and charging system
  • No Bluetooth, PC or app connection, so results cannot be logged or shared
