WUQ BT301 6V 12V Battery Tester

The WUQ BT301 is a digital battery analyser designed for 6V and 12V lead-acid batteries in cars, motorcycles, boats and light trucks. It measures state of health, cranking performance, charging voltage and alternator output on a colour LCD screen. The unit uses FOXWELL chip technology to deliver 99.9% accurate results in seconds. A 6.5ft cable allows testing inside or outside the vehicle without assistance.

Upgrade from basic load testers

This model replaces simple voltmeters or fixed-load testers that only show voltage under load. The jump is worth it when you need cranking time, cold cranking amp estimates and alternator diagnostics in one handheld tool. The enhanced UI and longer cable remove the guesswork of older probe-style devices. Professionals and DIY users gain a complete charging-system picture instead of a single voltage reading.

Suits owners maintaining mixed fleets

Ideal for DIY enthusiasts, home mechanics and small workshops that service SUVs, ATVs, tractors, golf carts and marine batteries. The tester covers flooded, AGM, EFB and GEL types across 6V and 12V systems. Not for buyers who need high-voltage EV pack analysis, industrial bench-grade cyclers or wireless data logging. Those requirements fall outside the supported voltage range and feature set.

Questions about this item

How long is the cable so I know if it reaches my battery?

The tester includes a nearly 6.5 ft cable that lets you reach the battery whether it sits inside the engine bay or outside the vehicle.

What is the correct way to attach the clip-on leads for a stable reading?

Clamp the leads firmly onto the clean battery terminals — positive to positive, negative to negative — so the solid mechanical connection prevents data loss during the test.

Does the analyser itself need calibration or a replaceable power source later?

The unit draws power from the battery under test, so there is no internal battery to swap and no periodic calibration is required.
