Professional Battery Diagnostics

The WUQ BT300P is a 12V and 24V battery tester designed for automotive technicians and serious DIY owners who need printed records of battery health, starter motor cranking status, and charging system condition across cars, trucks, motorcycles, boats and lawnmowers. It uses conductive testing technology to deliver results in roughly three seconds with a stated accuracy of 99.5 percent. Built-in thermal printing creates instant paper receipts without ink ribbons or cartridges.

Capacity And Headroom

The tester covers lead-acid batteries rated from 100 to 2000 CCA, including regular flooded, AGM flat plate, AGM spiral, Gel and EFB types. It reads 12V and 24V starter and charging systems, making it suitable for most light and medium-duty applications. Very large commercial batteries exceeding 2000 CCA fall outside the supported range, as do chemistries other than lead-acid. The 31.5 inch cable provides reach around engine bays but does not extend to remote battery locations on some heavy equipment.

Built-In Thermal Printer

The integrated thermal printer is the feature that distinguishes this unit from display-only testers, producing a permanent diagnostic receipt on standard thermal paper with no consumable ink or ribbons required. This makes the BT300P the right choice for workshops that must hand customers a printed health report or keep hard-copy records for warranty purposes. Buyers who only need on-screen readings and do not require printed documentation will not use this capability.

Questions about this item

Will the 12V 24V tester read a 100 CCA motorcycle battery and a 2000 CCA truck battery on the same clamps?

Yes, it tests 12V lead-acid batteries from 100 to 2000 CCA including flooded, AGM flat plate, AGM spiral, Gel and EFB types, and it also checks 12V and 24V starter and charging systems.

How do I know the 2.4 inch colour screen and built-in thermal printer are working right after I connect the clamps?

The screen shows crystal-clear readings in any light and the printer produces a diagnostic receipt in about three seconds using standard thermal paper with no ink or ribbons required.

Does the box include the 31.5 inch cable, spark-free copper clamps and a roll of thermal paper, or must I buy paper separately?

The tester comes with an extra-long 31.5 inch cable, spark-free copper clamps, PVC-coated wiring and a built-in printer; standard thermal paper is the only refillable supply needed.
