- App-based proof rather than a thermal slip
- Listed lead-acid batteries rated 100–2000 CCA
- You can use a compatible phone and app
TOPDON BT100W
The app-report choice for 12V battery and system checks. Choose it over a no-report handheld when sharing or saving a result changes your workflow.

Check it against my requirements
Who should skip it
- The workflow must avoid a phone or app.
- Printed proof is mandatory at the vehicle.
- You need 24V system testing.
What changes the decision
The W changes the handoff
App reports are the meaningful difference from BT100’s no-output record. Wireless connectivity alone would not be enough to satisfy proof.
Check app compatibility
Manufacturer instructions distinguish device and app functions. Confirm phone and app support before relying on the connected workflow.
Do not buy paper unnecessarily
BT300P is the nearby printed-proof path, with 24V system coverage as a separate addition. Neither should be chosen solely for a higher model number.

Is BT100W simply a wireless printer model?
No. Its verified output is an app report; a built-in printer is not recorded.
Does an app make the battery test broader?
No. The verified battery and system voltages stay at 12V regardless of how the result is viewed.
