The OBDMATE BT770 is the better pick for shop and heavy-duty use because its 100-2000CCA range covers far more lead-acid batteries, while the VDIAGTOOL BT600 suits mixed-voltage and lithium work with its 6V/12V/24V support. The BT770 handles 100-2000CCA on 12V and 24V systems, compared with the BT600’s 6V, 12V, and 24V coverage and no listed CCA range.

Choose the OBDMATE BT770 if you test a wide spread of lead-acid batteries and want a stated 100-2000CCA range with a 2.8″ color LCD.
Choose the VDIAGTOOL BT600 if you work on 6V systems or lithium batteries and want a 1.37 lb tester with a 5-year warranty.

I compared these two on battery type and voltage coverage, CCA range clarity, and printer design. My comparison is based on the listed specifications from both manufacturers, not on hands-on testing. The warranty length and screen size were the other two factors I weighed.

The biggest gap I found is battery chemistry coverage: the VDIAGTOOL BT600 handles 6V systems and lithium batteries, while the OBDMATE BT770 sticks to 12V and 24V lead-acid types but reaches a much wider 100-2000CCA range.

Individual Product Breakdown

I dug into the specs, ratings, and included accessories for each of these two battery testers with printers. Here’s my honest take on where each one shines and where it falls short.

Best Overall

OBDMATE 12V/24V Battery Tester with Printer OBDMATE BT770

100-2000CCA | 12V & 24V | 2.8″ Color LCD | 4.8 Stars (39 reviews) | 2.46 lbs

12V/24V Battery Tester with Printer OBDMATE BT770 Battery Load...

【Battery Tester for 12/24V Batteries】 BT770 Car battery tester works...
【One-click Battery Health Reports Printing】 Built-in thermal printer...
【Simple Process, Accurate Results】 BT770 accurately detects car battery...

I like the BT770 because its 100-2000CCA range covers just about any lead-acid battery you’ll meet in a shop, including regular flooded, AGM flat plate, AGM spiral, Gel, and EFB. The built-in thermal printer spits out a paper health report with one tap during cranking, charging, and battery tests, which is huge for customer communication. The 2.8″ color screen beats the common 2.4″ displays with bigger fonts and higher resolution, and the 4.8-star rating across 39 reviews backs that up. The main limitation is it only handles lead-acid chemistry, so modern lithium batteries are off the table.

✅ Pros

Huge 100-2000CCA range for cars, trucks, boats, and RVs
2.8″ color LCD with bigger fonts than the usual 2.4″ screens
Copper spark-free clamps with reverse polarity and overload protection
4.8-star rating from 39 buyers with a 1-year warranty

❌ Cons

No lithium battery support — lead-acid only
Heavier at 2.46 lbs, so less pocket-friendly
Only a 1-year warranty versus longer coverage elsewhere

VDIAGTOOL Car Battery Tester with Printer VDIAGTOOL BT600

6V/12V/24V | Lead-Acid & Lithium | 5-Year Warranty | 4.4 Stars (12 reviews) | 1.37 lbs

【Avoid Costly Breakdowns & No-Start Emergencies】Don’t wait until...
【Battery, Cranking & Charging System Test】A dead battery isn't always...
【Upgraded Anti-Jam Printing for Reliable Proof】The BT600 battery tester...

The BT600 wins on flexibility: it tests 6V, 12V, and 24V systems and supports lithium batteries alongside regular flooded, AGM, GEL, and EFB. The upgraded anti-jam thermal printer feeds paper smoothly and includes 3 rolls, and it’s plug-and-play with no charging needed. It’s lighter at 1.37 lbs and backs everything with a 5-year warranty, which is hard to beat. The catch is it doesn’t list a CCA range and isn’t compatible with deep cycle batteries, so heavy-duty deep cycle work needs a different tool.

✅ Pros

Tests 6V, 12V, and 24V plus lithium batteries
5-year warranty with lifetime software updates
Anti-jam printer with 3 rolls of paper included
Light at 1.37 lbs with plug-and-play setup

❌ Cons

No listed CCA range, so coverage is less clear
Not compatible with deep cycle batteries
Lower 4.4-star rating from just 12 reviews

Which One Should You Buy?

There’s no single winner here because the right battery tester with printer depends on what’s rolling into your bay. If you work mostly on lead-acid systems and want the widest CCA coverage, one wins; if you touch lithium or 6V setups, the other takes it.

OBDMATE BT770 is right for you if…

You need to test a huge spread of batteries, from a 100CCA lawn mower battery up to a 2000CCA truck battery, all on one tool.
You want a clearer 2.8″ color screen with bigger fonts than the usual 2.4″ displays for fast reads in a busy shop.
You want printed cranking and charging reports for customer sign-off and a 4.8-star track record from 39 buyers.

VDIAGTOOL BT600 is right for you if…

You work on 6V, 12V, and 24V systems and need one tester that covers all three voltages.
You service lithium batteries alongside lead-acid, where the BT770 simply can’t help you.
You want a 5-year warranty, lifetime software updates, and a light 1.37 lb tool you can carry on mobile calls.

❌ Who Should Skip All of These?

If you mainly test deep cycle batteries, skip both — the BT600 explicitly isn’t compatible with them, and the BT770 doesn’t list them either. You’d be better off with a tester built specifically for deep cycle and marine banks.

For most professional techs working on standard lead-acid vehicles, I’d grab the OBDMATE BT770 for its 100-2000CCA range and sharper 2.8″ screen. But if lithium or 6V work is on your bench, the VDIAGTOOL BT600 and its 5-year warranty is the smarter pick.

Frequently Asked Questions

Which is better for professional use, the OBDMATE BT770 or the VDIAGTOOL BT600?

For most professional techs working on standard lead-acid vehicles, I’d pick the OBDMATE BT770. Its 100-2000CCA range covers nearly every automotive battery you’ll see, and the 4.8-star rating from 39 buyers beats the BT600’s 4.4 stars from 12. But if your shop touches lithium or 6V systems, the VDIAGTOOL BT600 wins because the BT770 can’t test those at all.

Does the VDIAGTOOL BT600 test lithium batteries while the OBDMATE BT770 doesn’t?

Yes, that’s the clearest difference between them. The BT600 handles 6V, 12V, and 24V systems and supports lithium alongside regular flooded, AGM, GEL, and EFB. The BT770 sticks to 12V and 24V lead-acid types only, including regular flooded, AGM flat plate, AGM spiral, Gel, and EFB. If you service modern lithium-powered vehicles, the BT600 is the only one of the two that works.

Is the OBDMATE BT770 worth it over the VDIAGTOOL BT600 for a busy garage?

I think so if your work is lead-acid only and you want the widest coverage. The BT770’s 100-2000CCA range and 2.8″ color screen give you faster, clearer reads on a huge variety of batteries, and the spark-free copper clamps add real safety. The BT600 counters with a 5-year warranty and lifetime software updates, so it’s the better long-term value if you need lithium or 6V support.

Which battery tester with printer has the better warranty, the BT770 or the BT600?

The VDIAGTOOL BT600 wins this one easily with a 5-year warranty plus lifetime free software updates. The OBDMATE BT770 backs its tool with a 1-year warranty and 24/7 technical support. If long-term coverage matters most to you, the BT600 is the safer buy on paper.

Can the OBDMATE BT770 test 6V batteries like the VDIAGTOOL BT600 can?

No, the BT770 is built for 12V and 24V systems only, so 6V batteries are out of its range. The BT600 covers 6V, 12V, and 24V, making it the more flexible tool for older vehicles and specialty equipment. If you regularly see 6V batteries, the BT600 is the one to get.

Which one is easier to carry around for mobile service calls?

The VDIAGTOOL BT600 is noticeably lighter at 1.37 lbs versus the OBDMATE BT770 at 2.46 lbs. The BT600 is also plug-and-play with no charging required, so you can start testing the moment you reach the vehicle. For mobile techs and roadside work, that lighter weight and instant setup make the BT600 the more convenient pick.

My Final Verdict

After weighing both, I’m giving the win to the OBDMATE BT770. Its 100-2000CCA range covers nearly every lead-acid battery a pro will touch, the 2.8″ color screen is sharper than the usual 2.4″ displays, and its 4.8-star rating from 39 buyers beats the BT600’s 4.4 stars from 12. The VDIAGTOOL BT600 is the better pick only if you need 6V, lithium support, or its 5-year warranty.

If you’re on the fence, ask yourself one question: do I test lithium or 6V batteries? If no, the BT770’s wider CCA range and clearer screen make it the smarter buy. If yes, the BT600 is your only real option here.
