Compact 12V battery analyser

The FOXWELL BT100 PRO is a 12V battery tester covering 100 to 1100 CCA. It reads CCA, SOH, SOC, voltage and internal resistance on flooded, AGM, EFB and GEL batteries. A 2.4 inch backlit LCD shows clear GOOD, RECHARGE, REPLACE or BAD CELL results in nine languages. The unit weighs 170 grams and measures 6.69 by 1.97 by 6.69 inches.

DIY owners and mobile technicians

It suits drivers who want a quick health check before a trip, commuters tracking seasonal changes, and workshops needing a portable backup. Buyers who need integrated charging, alternator ripple analysis or data logging should look at a different class of tool.

Covers standard automotive range

The 100 to 1100 CCA span handles typical car, SUV and light-truck batteries with headroom for larger AGM packs. Testing stops at the upper CCA limit, so heavy-duty commercial or marine banks fall outside the measurement window.

Questions about this item

What type of vehicle battery does the BT100 PRO need to operate?

The tester is battery powered and draws energy from the 12V battery you are testing; no separate power source is required

Can the tester evaluate batteries rated under 100 CCA or over 1100 CCA that I might still have in other vehicles?

The stated testing range is 100-1100 CCA, so batteries outside that window cannot be measured accurately

How do I confirm the BT100 PRO is giving reliable results after I connect the clamps?

The 2.4 inch backlit LCD shows a clear status such as GOOD, RECHARGE, REPLACE or BAD CELL together with the measured CCA, voltage and internal resistance values
