Who this tester is actually for
Start with the job, not the model number.
Choose BT301 if...
- 12V flooded, AGM or GEL batteries
- 100–2000 CCA battery ratings
- Starting/charging work within the listed system voltages
- A screen result without a report requirement
Look at something else if...
- Your battery-health task includes 6V batteries.
- You need EFB support.
- You work on 24V starting/charging systems.
What changes the buying decision
Use these distinctions to rule this model in or out for your job.
Read both voltage rows
FOXWELL separates 12V battery analysis from 6V/12V system tests. Our finder keeps those permissions separate rather than calling this a universal 6V tester.
Step up from battery-only
Compared with BT100 Pro, system diagnostics and the 2000 CCA ceiling are the relevant additions, not the higher model number.
The next fork is truck systems
BT705 adds 24V system coverage and explicit EFB support. It still does not establish actual 24V battery testing. Related options: FOXWELL BT100 Pro / FOXWELL BT705.

Common questions
Can it satisfy the finder’s 6V + 12V battery choice?
No. Even with 6V system coverage, its battery-test list contains only 12V.
Does it create a customer report?
No shareable or printed output is verified here. Choose a report-capable alternative if the customer needs a record. Related buying forks: FOXWELL BT100 Pro / FOXWELL BT705. Check the remaining requirements in the finder.
