TOPDON BT100 12V Battery Tester

Description

TOPDON BT100 12V Battery Tester

The BT100 is TOPDON’s compact handheld tester for everyday 12-volt lead-acid battery and starting-charging checks. Official TOPDON U.S. specifications describe a 2-inch backlit display and a tool that is powered from the battery under test rather than from a built-in rechargeable pack.

Official test coverage

• 12-volt battery test for lead-acid batteries in the official 100–2000 CCA range (30–220 Ah on the GB scale)
• Supported rating standards: CCA, CA, BCI, MCA, DIN, IEC, EN, SAE, JIS, and GB
• 12-volt cranking test to review starting performance
• 12-volt charging-system test, including a ripple test
• Intended for flooded, AGM, and other conventional lead-acid 12V batteries as described by TOPDON

Official specification flags show that the BT100 does not test 6-volt or 24-volt systems. If you need 24-volt coverage, compare the TOPDON BT200.

This tool reports battery, starter, and charging health. It is not a diagnostic scan tablet and does not register a replacement battery in the vehicle’s module.

Confirm the battery type, voltage, and CCA (or equivalent) rating before testing.
