Customize battery load tester to Fit Your Brand Needs
From concept to delivery, we manage each step with strict precision — making your customized automotive battery tester project seamless, efficient, and perfectly aligned with your brand.

Step 1. Consultation & Requirement Analysis
We begin by understanding your business model, target market, and product positioning.
Our sales and engineering teams will work closely with you to discuss:
- Testing functions required: voltage, current, internal resistance, CCA, etc.
- Application scenarios: repair shops, 4S centers, battery stores, DIY users
- Design preferences: exterior style, button layout, display type, housing color
- Branding needs: logo customization, UI interface, packaging design
Goal: to deliver a car battery tester solution that perfectly matches your brand and market requirements.
Step 2. Design Review & Component Selection
After clarifying your needs, we proceed to:
- Review or refine your exterior design files
- Confirm details such as screen type, button layout, housing structure, and interface ports
- Assist in selecting key electronic components, including:
- High-precision measurement chips
- Stable power-management modules
- Heat-resistant and flame-retardant housing materials
- Battery clamps, cables, and protection circuitry
- Provide free exterior or UI design if needed
This ensures your product maintains accuracy, durability, and strong brand identity.


Step 3. Quotation & Order Confirmation
Once the design, specifications, and component selections are finalized, we will:
- Provide a detailed quotation based on hardware configuration and production processes
- Confirm order terms and payment conditions
- Begin scheduling engineering samples and production timelines
Your customization project officially enters execution at this stage.
Step 4. Sample Production & Approval
We can offer:
- Free standard samples for functional evaluation
- Customized engineering samples based on your branding and specifications
You may evaluate:
- Measurement accuracy
- Display clarity and layout
- Housing structure, feel, ergonomics
- Logo or panel design
- Anti-interference performance and safety features
Once approved, the project moves on to mass production.


Step 5. Mass Production & Quality Inspection
During mass production, our products go through SMT and PCBA assembly, structural assembly, calibration, and aging tests. Each unit is rigorously checked for accuracy, temperature stability, cable durability, button lifespan, drop resistance, and housing strength to ensure consistent high quality.
Step 6. Packaging & Global Delivery
All finished products are packaged with:
- Protective shock-proof materials
- Customized branded boxes (optional)
- Export-standard outer cartons
We offer flexible global shipping methods:
- Sea freight
- Air freight
- Express delivery (DHL, FedEx, UPS, etc.)
Ensuring your order arrives safely, quickly, and in excellent condition.


Step 7. After-sales Service & Reorder Support
After delivery, we continue to support your brand with:
- Feedback collection on product performance and user experience
- Optimization of features, appearance, or cost for future orders
- Long-term availability of spare parts and technical support
Helping your brand continuously improve product competitiveness in the market.

Battery Health Calculator
Quick check: enter measured battery voltage and Cold Cranking Amps (CCA). This tool gives a fast, practical assessment to help decide if a battery needs charging or replacement.
For best accuracy, use data measured directly by the WT07 Car Battery Tester (Voltage / CCA / SOH / SOC / Internal Resistance).
The open-circuit voltage reflects the state of charge (SOC). For a typical 12V lead-acid battery:
- 12.7–12.6V: Fully charged
- 12.5–12.4V: ~75% charged
- 12.3–12.2V: ~50% charged
- 12.1–12.0V: Low charge
- <11.9V: Deeply discharged
Long-term low voltage causes sulfation and permanent capacity loss. Voltage is therefore a core indicator in battery evaluation.
CCA indicates a battery’s ability to start an engine under low-temperature conditions. Higher CCA = stronger starting performance.
Typical evaluation:
- ≥450A: Good starting ability
- 300–449A: Reduced performance
- <300A: Weak, replacement recommended
A battery may show “normal voltage” but have significantly reduced CCA — meaning it can no longer reliably start the engine.
Temperature greatly affects battery capacity and CCA:
- −10°C: Capacity may drop by ~30%
- −20°C: Capacity may drop by 50% or more
Cold weather can cause unexpected starting failures even if the battery seems healthy at room temperature.
The Battery Health Calculator evaluates the combined effects of:
- Voltage → Charge level & sulfation risk
- CCA → Engine starting capability
- Temperature → Real-world performance impact
This comprehensive evaluation provides a more accurate conclusion than relying on a single measurement.
WT07 is a professional automotive battery tester compatible with Lead-Acid, AGM, EFB, and GEL batteries. It accurately measures:
Enter WT07 readings into the calculator for fast, accurate assessment of whether the battery can continue to be used, needs charging, or should be replaced.
