Upgrade NT301 Plus FOXWELL OBD2 Scanner Battery Tester 12V Review

Want a diagnostic tool that does more than read codes? The Upgrade NT301 Plus FOXWELL OBD2 Scanner Battery Tester 12V handles four jobs in one. It reads check engine codes, tests your battery, checks the charging system, and tests the cranking system. It works with a wide range of vehicles and shows live data, so you can spot problems early and skip a lot of trips to the shop.

Why Consider This Product?

If you want one tool that reads codes and tests your battery, the Upgrade NT301 Plus FOXWELL OBD2 Scanner Battery Tester earns its spot in your toolbox. It packs several useful features into one handheld unit that works for both home garages and busy shops. If you want to see how this stacks up against the original model, our FOXWELL NT301 OBD2 Scanner review breaks down the standard version that this Plus model builds on.

Catching engine and battery trouble early keeps your car running better and cuts down on surprise breakdowns. This scanner lets you pull check engine codes, watch live engine data, and run battery tests right in your driveway.

The scanner carries automotive industry certifications that back up its accuracy. Owners also report solid results in their reviews, which says a lot about how it holds up in real use.

Features and Benefits

Live Data Stream

The live data stream shows what your engine is doing in real time. You can watch the engine’s operating numbers as they change and catch a small problem before it turns into a big repair.

Battery Tester

The built-in battery tester checks capacity and runs a cranking system test. It reads voltage, current, and reserve capacity so you know exactly how much life your battery has left. That’s handy if you drive in cold or harsh conditions where a weak battery tends to quit on you.

Check Engine Code Reader

Reading and clearing check engine codes is quick and simple. The scanner pulls the trouble codes and gives you plain descriptions, so you know what’s wrong and what to do next. A lot of small faults that would cost you a diagnostic fee are easy to handle yourself.

EVAP System Testing

It also runs EVAP system tests, which check the fuel vapor system for leaks. A leak here can trip the check engine light and hurt your emissions, so finding it at home saves you a shop visit and keeps your car running clean. For folks who need deeper system coverage and ABS or SRS diagnostics, our FOXWELL NT624 Elite scanner review covers a more advanced option from the same brand.

Product Quality

This scanner is built to take a beating. The tough outer casing shrugs off the bumps and drops that come with garage work, whether you’re a pro or working on your own car. The color screen stays readable in bright sunlight, and the menus are simple enough that you won’t need the manual to find your way around.

What It’s Used For

Vehicle Diagnostics

The scanner’s main job is reading vehicle data. Plug it into your car’s OBD2 port and you can see things like engine RPM, oxygen sensor readings, and fuel trim values. That information helps you pin down problems and keep your car running its best.

Check Engine Light

Chasing down a check engine light is where this scanner shines. When that light pops on, it means something’s off with your engine. Hook up the scanner and it pulls the trouble code with a clear description, so you can deal with the problem right away.

Battery Testing

Want to know if your battery is on its way out? The tester reads voltage, current, and reserve capacity to tell you whether it needs a charge or a replacement. That heads off the no-start surprise on a cold morning.

Cranking System Test

The cranking system test checks how well your engine starts by reading the electrical system during cranking. It points you toward problems with the starter motor, ignition switch, or battery cables before they leave you stranded.
