Direct answer
Require explicit EFB support rather than assuming every AGM-capable tester covers EFB.

Require explicit EFB support rather than assuming every AGM-capable tester covers EFB.
Common confusion
EFB and AGM need separate support. Do not assume a tester covers both.
Top-fit snapshot
These illustrate different buying forks, not a ranked list or a substitute for the finder.
ANCEL BST100
Explicit EFB with 12V system diagnostics and no report hardware. BA101’s subset does not credit EFB.
See verified details →LAUNCH BST560S
12V EFB work with QR proof; the numerical CCA range remains unverified.
See verified details →SOLAR / Clore BA327
EFB with paper output and 40–2000 CCA; 6V/12V battery and 12V/24V system scope are separate.
See verified details →What changes the decision
EFB is its own selection
Enhanced flooded is not an AGM synonym. Clore describes EFB-specific evaluation; selecting an AGM-capable tool without explicit EFB evidence leaves a chemistry gap.
Manufacturer evidence ↗: Clore explains EFB-specific testing rather than treating AGM and EFB as interchangeable labels.
Read chemistry before start-stop
A start-stop badge on the vehicle is not enough to choose the tester setting. Identify the battery actually installed and use its rating, not a presumed original specification.
Do not confuse testing with replacement setup
An EFB health test does not establish battery registration, coding or permission to replace EFB with another chemistry. Those decisions need the vehicle procedure.
Frequently asked questions
Why is BA101 not listed for EFB?
Its verified battery-type list does not include EFB. BST100 explicitly includes it, so that difference can change eligibility even within one brand.
Does any tool labeled lead-acid qualify?
No. The finder requires explicit EFB support for a known EFB input; an unspecified lead-acid field does not pass by assumption.
What should a customer-proof buyer compare?
Choose the output after chemistry: BST560S offers QR, while BA327 prints. Use the printer guide if a paper work order is mandatory.
