Best Battery Tester with Printer: Eight Listings Compared

As an Amazon Associate we earn from qualifying purchases. Details

The person typing best battery tester with printer wants a tester that checks a vehicle battery and prints the result for a record. This guide works only from the 12 listings in our research set, and it covers what each one states and what it leaves out. Work on mains circuits can kill, so a meter’s CAT rating must suit any circuit it is used on, and panel or service work belongs to a licensed electrician. None of the 12 listings states a CAT rating. These are vehicle battery testers, not mains meters.

Quick answer

• Eight of the twelve listings are carded below. Four are left out for the reasons in the section on listings without a card.
• Four of the eight picks state a 100-2000 CCA range. One states 30-2000, and one states 10-2000 only in its highlight line.
• Three listings claim lithium support, and one says the opposite. Confirm lithium use with the seller before you test a lithium cell.
• Warranty length is stated for four of the eight picks. The VDIAGTOOL BT600 states the longest term, 5 years.
• No listing states a CAT rating, so none of these testers should be used on household mains.

Electrical safety before you test or print

Work on mains circuits can kill. A car battery tester clips to a battery, but buyers often keep one near household wiring, and a meter used on the wrong circuit is a hazard. The meter’s CAT rating must suit the circuit it touches. None of the 12 listings states a CAT rating, so for each of them the listing does not state a CAT rating, and none should be used on household mains. Panel and service work belongs to a licensed electrician.

Charging and testing lead-acid batteries carries its own hazards, and those hazards apply to the battery, not only to the tester. The Purdue Herrick Laboratories battery safety sheet says hydrogen is “Flammable in nature.” It gives an “Explosive mixture at 4 – 74% by volume of air.” The same sheet says to “Prevent open flames, sparks, or electric arcs in battery charging areas.” The UC Riverside lead-acid sheet says “Batteries with low electrolyte levels can explode when charging as the gas builds up in the battery case.” The Crown Battery safety data sheet says “Batteries being charged will generate and release flammable hydrogen gas,” and it advises “Wear face and eye protection when near batteries being charged.” The same data sheet warns of “a possible risk of electric shock from charging equipment.”

These sheets describe charging and handling in general. They do not test any tester in this list, and they do not say whether a given printer or clamp is safe to use near a battery. Use them as handling rules, and read each listing for its own limits. For how a voltage tester reads a battery, see how voltage testers work. For a general meter, see best hand held digital multimeter, and for a vehicle voltage check, see best digital voltage meter for car.

Comparison table from the listings

The table uses only what each listing states. A blank would mean the listing is silent, so each silent cell says not stated. Model names come from the listing’s own specification line, and the title is noted where the two differ.

Listing (ASIN)	Model in listing	Battery voltage stated	CCA range stated	Paper rolls stated	Warranty stated
OBDMONSTER	BM550U	6V, 12V, 24V	100-2000 CCA	2 rolls	not stated
KONNWEI	KW700	12V and 24V	10-2000 CCA (highlight)	2 rolls	not stated
OBDMATE	BT770	12V and 24V	100-2000 CCA	2 rolls	1 year
VDIAGTOOL	BT600	6V, 12V, 24V	not stated	3 rolls	5 years
LAUNCH	BST-860 (title: BST-860S)	12V	not stated	not stated	not stated
ANCEL	BST600	12V and 24V	100-2000 CCA	with print paper, count not stated	not stated
AUTOOL	Part 001, title BT760	12V and 24V	30-2000 CCA	2 rolls	3-year limited
OBDResource	OBD-BM550ULTRA	6V, 12V, 24V	100-2000 CCA	not stated	1 year
Lancol	LC310	12V and 24V	100-2000 CCA	not stated	not stated
Clore	BA227	12V	100-1400 CCA	1 roll	1 year
AUTOOL	BT760	not stated	not stated	not stated	3 year manufacturer
Bosch	BAT155	6V and 12V	100 to 6,000 CCA	not stated	not stated (field reads “Per Contract with Amazon”)

Two other figures appear in listing text but not in the table. The Bosch listing states a testing range of 1.5VDC to 60VDC. The LAUNCH listing states a health report within 3 seconds.

The eight picks, from their listings

Each pick below uses only the text of its own listing. Where a listing contradicts itself, the section says so.

OBDMONSTER BM550U: the fullest stated feature set

The listing says the BM550U prints a battery diagnosis report, and its highlight line names 100-2000CCA and a 1.8 inch HD screen. The specification lines list ohmmeter, voltmeter and ammeter measurement types, and the paper is described as 57mm wide by 30mm core diameter. Two standard rolls of thermal paper come in the box.

The limits are real. The listing names no warranty length. One bullet about lithium batteries stops mid-sentence in the research record, so the listing gives no complete lithium answer for this model. Skip it if you need a warranty term or a clear lithium answer.

KONNWEI KW700: printing with a QR code

The listing says results can be scanned with a QR code and viewed in a smartphone browser, with no app required. Its bullets name 12V and 24V coverage, a 2.8-inch color LCD and two paper rolls. The bullets also say the tester covers lithium batteries.

The highlight line states 10-2000CCA, which starts lower than the 100 most other listings state. No warranty length appears in the listing. Skip it if the starting CCA figure matters to your vehicles, or if you need a stated warranty term.

OBDMATE BT770: a 1-year warranty and two rolls

The listing says the BT770 prints one-tap reports during the cranking test, the charging test and the battery test. Its bullets state 100-2000 CCA for 12V lead-acid batteries, a 2.8-inch color display and a 31.5-inch cable. The package holds two paper rolls, a USB-C cable and a hard carry case. The warranty is stated as one year with technical support.

The power source specification reads Corded Electric, while the bullets never say how the unit is powered. The listing does not explain that field, so ask the seller before you buy. The listing names no lithium support. Skip it if lithium cells are your main use.

VDIAGTOOL BT600: the longest stated warranty

The listing states a 5 years warranty and lifetime free software updates. It names 6V, 12V and 24V systems, Regular Flooded, AGM, GEL and EFB batteries, and a Type-C cable. The package includes three rolls of thermal paper, which is the largest roll count among the eight picks.

The listing names no CCA range, either in its specification or in its bullets. Its title says Lead-Acid & Lithium, and one bullet says it works with advanced lithium batteries, so the lithium claim is stated but not explained. Skip it if you need a CCA figure to compare against your battery label.

LAUNCH BST-860S: six functions with a model mismatch

The bullets say the tester supports six battery and electrical test functions: ripple detection, battery test, electric current test, starter test, charging system test and voltage test. They also say a health report prints within 3 seconds through a built-in thermal printer. The listing names CCA, BCI, CA, MCA, JLS, DIN, IEC, EN, SAE and GB standards, and its specification lines list CE, IEC 61010-1, EN 61010-1 and RoHS.

The title says BST-860S, while the model specification says BST-860. The listing gives no paper roll count, no CCA range and no warranty length. Skip it if you need a stated CCA range or stated paper counts before you buy.

ANCEL BST600: the most detailed printed report

The bullets list what the printout contains: battery type, SOH, SOC, rated and measured CCA, voltage, internal resistance, temperature and the test result. The printer can also add the last four VIN digits, the date and the time. The bullets state that the tester draws power from the connected vehicle battery and has no internal battery.

The listing says it is not for lithium batteries or EV high-voltage battery packs, which conflicts with the lithium claims on three other listings. The listing gives no warranty length, and the paper count is not stated. Skip it if you need lithium or EV battery checks.

OBDResource OBD-BM550ULTRA: an AH-to-CCA converter

The bullets say the tester converts AH to CCA for batteries rated from 2AH to 220AH, so you enter the AH value and read the CCA result without a chart. The display shows voltage, SOH, SOC, CCA and internal resistance on a 1.8-inch color screen, and a voltage waveform appears during the test.

The model field reads OBD-BM550ULTRA, but the included components line names a BM510 Device. The specification also lists a 2 A Maximum Alternating Current field that the bullets do not explain. The listing states a 1 Year Warranty. Skip it if the device mismatch matters to you, and ask the seller which unit ships.

AUTOOL 30-2000 CCA listing: the widest stated CCA range

The bullets state a 30-2000 CCA test range and a 3.2-inch color screen. The printer prints after each detection, which the listing presents as a way to create formal work order records. The specification lines state a 3-year limited warranty, and the bullets add a 1-year repair service for accessories.

The part number reads 001, while the title names BT760. The listing describes four diagnostic functions and gives no test standard for them. Skip it if you need a lithium answer, because the listing does not address lithium.

How we chose

We read all 12 listing records in the research set on 2026-10-23. The first test was whether the listing states a printer for test results. The second was whether it states a battery voltage or a CCA figure. The third was whether the title, model line and included components agree with one another. Every record passed the first two tests, so this guide used the third and the amount of stated fact to pick eight.

This is a selection of eight from twelve, not a ranking. We did not score or order the listings for quality, and we did not add any product from outside the research set. The four listings left out had either a mismatch between their own fields or fewer stated facts than the eight picks.

Listings without a card

• Clore BA227. It states 12V coverage, a 100-1400 CCA range, one thermal paper roll and a 1 year warranty. Its CCA ceiling is lower than the 2000 that most picks state, and it names no 24V coverage.
• Lancol LC310. It states 12V and 24V coverage with 100-2000 CCA, a 2.4-inch LCD and a built-in thermal printer. Its bullets claim more than 99.6% precise testing results, but the listing names no test method behind that figure, and it gives no warranty length.
• AUTOOL BT760. Its title and bullets describe a battery tester with a thermal printer. Its included components line names a Pulsating Brake Fluid Bleeder and no tester, so the listing contradicts itself.
• Bosch BAT155. It covers 6V and 12V batteries with 100 to 6,000 CCA and a 1.5VDC to 60VDC testing range, and it has an integrated printer. The listing describes a heavy duty commercial tool, and its warranty field reads “Per Contract with Amazon,” which is not a warranty term.

What we could not verify

• Accuracy. No listing gives an independent accuracy test. The 99.6% figure on the Lancol listing is the manufacturer’s own claim.
• CCA ranges for the VDIAGTOOL BT600 and the LAUNCH BST-860S. Neither listing states one.
• Paper roll counts for the LAUNCH, ANCEL, Lancol, OBDResource, the second AUTOOL listing and Bosch.
• Lithium support. The listings disagree: VDIAGTOOL, KONNWEI and Lancol state lithium claims, and ANCEL says its tester is not for lithium batteries.
• The CCA definition and the test temperature behind each rating. The sources we opened do not define CCA, so this guide does not explain how the ratings are measured.
• Printing speed beyond the LAUNCH and Lancol claims, which are the manufacturers’ own figures.

Buying checklist

• Confirm the battery voltage on your vehicle and the CCA range you need against the table.
• Ask the seller in writing whether the tester supports lithium, and check the answer against the listing text.
• Confirm the paper roll count and paper size. Only the OBDMONSTER listing gives a paper size.
• Check the warranty term and whether it covers the printer.
• Check that the model number on the box matches the title. Two listings in this set do not match.

Mistakes to avoid

• Assuming that a printer implies a warranty or a paper count. Several listings state neither.
• Testing near a charging battery without ventilation. The Purdue sheet asks for a well ventilated charging area.
• Trusting a lithium claim without a seller answer, when other listings in the same set say the opposite.
• Using a car battery tester as a mains meter. None of the listings states a CAT rating.

FAQ

Does a battery tester with a printer work on lithium batteries?

The answer depends on the listing. KONNWEI, Lancol and VDIAGTOOL state lithium claims in their text, and ANCEL says its tester is not for lithium batteries. The OBDMATE bullets list flooded, AGM, gel and EFB types but not lithium. Confirm with the seller before you test a lithium cell.

Which listing states the longest warranty?

The VDIAGTOOL BT600 states a 5 years warranty, and it adds lifetime free software updates. The AUTOOL 30-2000 CCA listing states a 3-year limited warranty, and the second AUTOOL listing states a 3 year manufacturer warranty.

Does a car battery tester need a CAT rating?

A tester used on household mains needs a CAT rating that suits the circuit. None of the 12 listings states a CAT rating, so none is safe to call suitable for mains. Work on mains circuits can kill, and panel or service work belongs to a licensed electrician.

Can I print a result while the battery is on charge?

The listings do not say whether testing during charging is safe. The sources we opened cover charging areas: keep the area ventilated, keep sparks and flames away, and wear eye protection, as the Crown Battery data sheet advises. The UC Riverside sheet says to turn the charger off immediately if you notice the smell of rotten eggs, which it identifies as hydrogen sulfide.

Why do the CCA ranges differ between listings?

The listings state different figures: 10-2000 CCA in the KONNWEI highlight, 30-2000 in AUTOOL, 100-2000 in four picks, 100-1400 in Clore, and 100 to 6,000 in Bosch. The sources we opened do not explain why the ranges differ. Compare the figure in each listing with the CCA printed on your battery label.

Bottom line

Start with the battery you own: check its voltage and CCA need against the table, then confirm the lithium answer and the warranty with the seller before you buy. Pick the listing whose stated facts match your work. Keep every tester away from household mains, because none of these listings states a CAT rating.
