On‑Site Quality Monitoring Throughout Production
Quality control at Linjia is integrated into daily production rather than left to final inspection. Our manufacturing and quality teams stay closely involved throughout the production process, monitoring key production stages and checking that manufacturing continues to follow the confirmed project requirements.
When an abnormality or process concern appears, the relevant teams can review it directly during production rather than waiting until the finished chargers reach the end of the line. With engineering, manufacturing, and quality functions working within the same factory system, potential issues can be identified earlier and production decisions can be made more efficiently
Linjia as Your Professional Battery Charger Manufacturer
Battery Charging Expertise
Our core technical team has more than 20 years of experience in charging power technology, supporting 6V‑72V lead‑acid and LiFePO4 charger projects.
Integrated Manufacturing
Linjia connects SMT production, assembly, potting, in‑house housing injection moulding, electrical testing, burn‑in, labelling, and packing within one manufacturing system.
Quality Control
Standardised quality checkpoints include incoming inspection, semi‑finished testing, finished‑product electrical testing, high‑voltage insulation testing, and full‑load burn‑in.
OEM / ODM Customisation
Projects can cover charging current and profile, plugs, connectors, cables, housings, labels, packaging, and, where required, new circuit, PCB, structural, appearance, and private‑mould development.
Quality and Compliance Built Around the Actual Project
Linjia operates under an ISO 9001 quality management system. Relevant charger models can also be supported by CE certification and applicable IEC testing documentation according to the selected model, electrical specification, and destination‑market requirements.
• ISO 9001 Quality Management System
• CE certification support for applicable models
• Applicable IEC testing documentation
• Project‑specific compliance review before production approval
Important: Certification scope should be confirmed for the exact charger model and target market. Do not present CE or IEC as universal coverage for every Linjia charger.
Support Does Not Stop When the Order Ships
For OEM and ODM projects, Linjia keeps the approved charger specification, sample requirements, connector and polarity definitions, label information, packaging configuration, and production records as project references. These records help maintain consistency for repeat orders and support technical review if a field issue is reported.
Before Shipment : Confirm key electrical parameters, interfaces, labels, packaging, and order requirements against the approved project reference.
Repeat Orders : Retain approved specifications and project references so later orders can follow the confirmed configuration.
Technical Issues Are Reviewed with Data, Not Guesswork
If a charger issue occurs in the market, the buyer can provide the model, production batch, symptoms, battery information, operating conditions, photos or video, and available test data. Linjia’s engineering team can review the information, analyse possible causes, and define appropriate containment or corrective follow‑up actions.
ISSUE‑HANDLING FLOW
• 1. Issue Information
• 2. Engineering Review
• 3. Cause Analysis
• 4. Containment Action
• 5. Corrective Action & Follow‑Up
Clear Records Help Keep the Approved Charger Consistent
Approved Specification Records
Record the approved electrical parameters, connector, polarity, cables, labels, and packaging requirements as the production reference.
Sample & Change Control
Mass production follows the approved sample and confirmed specification. Important project changes should be reviewed and reconfirmed before introduction.
Batch Identification
Model, label, order, and production‑batch information can support traceability when technical review is required.

We're Here to Answer All Your Questions
What information do you need to recommend a battery charger?
Please provide the battery type, nominal voltage, full‑charge voltage if available, capacity, BMS requirements, local AC input, plug type, output connector and polarity, application, operating environment, and estimated quantity.
Do you support OEM and ODM customisation?
Yes. Customisation can cover charging current and profile, plugs, connectors, cables, housings, labels, packaging, and, where required, new circuit, PCB, structural, appearance, and private‑mould development.
What quality checks are included before shipment?
The standard quality‑control process includes incoming material inspection, semi‑finished product testing, finished‑product electrical performance testing, withstand voltage and insulation testing, full‑load burn‑in, and final order verification before shipment. Specific testing items and requirements may vary depending on the charger model and individual project specifications.
Can you support CE or IEC documentation for our market?
Linjia is ISO 9001 certified. Relevant models can be supported by CE certification and applicable IEC testing documentation depending on the charger model, electrical specification, and target‑market requirement.
How are MOQ and production lead time determined?
MOQ and lead time depend on the charger model, level of customisation, tooling or material requirements, testing scope, sample approval, and order quantity. They should be confirmed after the project specification is clear.
