Say goodbye to breakdowns on the road – check your battery’s true condition in 3 seconds
Unable to start the engine on a winter morning, or struggling to start the car after listening to music for half an hour whilst parked… These problems are often not caused by a faulty battery, but by the fact that you don’t know its true condition.
The CZD10 Multifunctional Battery Tester tells you in 3 seconds whether your battery is ‘good’ or ‘needs replacing’ — no need to remove it, no need to discharge it, and it won’t damage the battery; even female drivers can use it with ease.
One device for testing, covering all your motoring scenarios
With more and more in-car electronics, the load on your battery is increasing.
Dashcams, car fridges, car audio systems… Every additional load shortens the battery’s lifespan. The CZD10 handles it all:
Cars: private saloons, SUVs, people carriers
Lorries/vans: automatic recognition of 12V/24V systems
Motorbikes: quick check of starter battery condition
Construction vehicles/forklifts: battery health assessment for heavy-duty equipment
Electric vehicles: maintenance and testing of lead-acid batteries
Suitable for all types of 12V/24V lead-acid batteries, including standard, AGM, GEL and EFB batteries.
Large colour screen, displaying all test results at a glance
Say goodbye to the hassle of switching between small screens. The CZD10 is equipped with a smart, large colour screen that displays all key data on a single screen:
Test Items: Description
Battery Life: Displayed as a percentage, providing an intuitive understanding of remaining life
Remaining Charge: Real-time monitoring of the battery’s charge status
Internal Resistance: The higher the internal resistance, the poorer the performance
Voltage: Current terminal voltage of the battery
Cold Cranking Amps (CCA): A core indicator of cold-weather starting capability
Cranking Current (CA): An assessment of starting capability at normal temperatures
Test results are clearly presented in four categories: ‘Excellent’, ‘Good’, ‘Poor’ and ‘Replace’—when the battery condition is poor, a flashing red warning makes the issue immediately apparent.
Supports six major international standards, with professional-grade testing accuracy
The CZD10 incorporates multiple battery rating standards, ensuring precise matching regardless of the standard used to label your battery:
Standard Code Full Name Main Regions of Use
SAE: Society of Automotive Engineers Standard North America
EN: European Standard Europe
DIN: German Standard Germany and parts of Europe
IEC: International Electrotechnical Commission Standard Internationally recognised
CCA: Cold Cranking Amps Globally recognised
CA: Cranking Amps North America
The CCA measurement range covers 100–1999 CCA, meeting all testing requirements from motorcycles to heavy goods vehicles.
Intelligent safety features ensure even beginners can use it with confidence
Not familiar with circuits? Worried about reversing the polarity and damaging the device? The CZD10 has you covered.
Reverse polarity protection: Automatic protection if the red and black clamps are connected incorrectly, preventing damage to the device
Reverse Polarity Protection: Automatically cuts off power when the input voltage is too high, ensuring safety
Poor Contact Alert: When the clamps are not securely fastened, the corresponding clamp icon flashes and a voice alert sounds – a flashing red clamp indicates poor positive contact, making it immediately clear
Red for positive, black for negative; just clamp them securely – it’s that simple.

Who needs this tester?
Car owners: Perform regular self-checks on battery health to avoid being unable to start the engine on cold winter mornings
Repair shops/authorised dealerships: Quickly determine whether a battery needs replacing to improve service efficiency
Fleet managers: Regularly screen for potential battery issues to prevent vehicles breaking down on the road
Battery dealers: Test the quality of stock batteries and weed out defective units
When should you replace your battery? Let the data tell you the answer
Many car owners replace their batteries purely on a ‘hunch’—replacing them when starting becomes difficult, only to find the removed battery could have lasted another six months.
The CZD10 reveals the truth through three key metrics: internal resistance, CCA and remaining life percentage:
The lower the internal resistance, the better the battery’s performance
The higher the CCA, the stronger the cold-weather starting capability
Replacement is recommended when the remaining life percentage falls below 60%
No more replacing batteries blindly; no more wasting money.
