Battery problems mimic other faults — a weak cell can trigger low-voltage codes across multiple modules. Testing the battery first saves time and money before chasing sensor replacements.
What the BT100 Pro Measures
The BT100 Pro analyzes cranking amps (CCA), state of charge (SOC), state of health (SOH), and voltage under load. Results appear in seconds with a clear good/replace recommendation.
When to Test
Test before winter, after jump-starts, when the engine cranks slowly, or whenever you see charging-system related codes. Pair with an OBD2 scanner to correlate voltage data with module faults.
BT100 vs. BT705
The BT100 is a dedicated battery analyzer. The BT705 adds 12V/24V testing plus OBD2 scanning and ABS bleed on one device — ideal if you want a single toolbox solution.
