I. SRRC Certification: The "Market Access Pass" for Wireless Battery-Powered Products

Type Approval for Radio Transmitting Equipment (SRRC Certification) is a mandatory administrative license for selling wireless devices in China. For products such as energy storage batteries with wireless modules, outdoor power supplies, and intelligent battery management devices, failure to obtain SRRC certification risks market bans and penalties. Especially with all old-standard certificates set to expire by December 31, 2025, and stricter new regulations in place, battery-powered products—characterized by the "intertwining of wireless performance and battery safety"—face significantly heightened certification difficulty.

II. 3 Core Challenges of Battery-Powered Product Certification Under 2025 New Rules

1. Tighter Frequency Band Limits: Battery Power Stability Becomes a Critical Variable

The new rules drastically tighten spurious emission limits for the 2.4G, 5.1G, and 5.8G frequency bands: In the 2483.5~2500MHz band, the limit is stricter from -33dBm/100kHz to -40dBm/1MHz—a nearly 20dB increase in stringency after conversion. For battery-powered products, excessive power supply ripple or voltage fluctuations during endurance testing can easily cause radio frequency (RF) performance drift, leading to FAIL results in high-channel sideband tests (typically manifested as a stepped drop in waveform).

2. New Interference Avoidance Testing: Sharply Increased Difficulty in Multi-Scenario Adaptation

The new rules require 2.4G band devices to stop transmission within 13ms after detecting channel occupancy, and 5G band devices within 20ms—with a short control signal duty cycle ≤10%. However, battery-powered products often operate under extreme conditions (e.g., high/low temperatures, low battery), and traditional testing fails to cover all scenarios. The 5.8G band, in particular, carries the highest interference avoidance risk due to the lack of reference from old rules or CE standards.

3. Linkage Between Battery and Wireless Parameters: Uncontrollable Certification Cycles

Battery capacity degradation and electromagnetic compatibility (EMC) issues between Battery Management System (BMS) signals and wireless modules may cause excessive transmit power or insufficient receive sensitivity. Without targeted pre-testing, enterprises easily fall into a "test-rework-retest" cycle, delaying certificate acquisition.

III. Guangdong Energy Storage Testing: Core Advantages in Solving SRRC Certification Challenges

We provide end-to-end compliance solutions:

1. New-Rule-Specific Pre-Testing System to Boost First-Time Pass Rate

Our customized pre-testing covers critical risk points for battery-powered products, including:

• Battery power supply stability testing (ripple, voltage fluctuation under load);
• RF performance verification under extreme battery conditions (low power, high/low temperature);
• Simulation of interference avoidance scenarios (multi-channel occupancy, signal collision).

This proactively identifies issues before formal testing, minimizing retest costs.

2. Senior Team Reduces Cycles by 40%

Led by a team of PhDs, our core engineers have over 10 years of SRRC certification experience. They are well-versed in new rule requirements such as "synthetic antenna gain calculation" and "Bluetooth adaptive testing," enabling rapid review of technical documents (including battery BOMs, wireless module parameter matching tables).

3. Full-Lifecycle Compliance Support

• Transition Period Emergency Solutions: For products with expiring old certificates, we offer one-stop services including "new standard upgrade evaluation + certificate extension application" to ensure seamless market sales continuity.
• Post-Certification Maintenance: Our senior engineers provide ongoing support such as certificate consultation and update reminders.

4. Authoritative Qualifications Ensure Credibility

Our laboratory is CNAS-accredited and maintains close technical communication with the Radio Management Bureau of the Ministry of Industry and Information Technology (MIIT). Our testing methods align with those of the "Radio Regulatory Commission," guaranteeing high first-time pass rates. We have successfully helped hundreds of enterprises obtain SRRC certification, covering wireless battery-powered products, routers, servers, EV chargers, wireless modules, and more.

IV. Certification Process: 3 Steps to Efficiently Obtain Certificates

1. Pre-Diagnosis Phase: Complete product evaluation (wireless module model, frequency band parameters) and issue a risk report within 1 working day.
2. Testing & Rework Phase: Conduct formal testing while providing real-time technical support for rework (e.g., optimizing battery power supply circuits, adjusting wireless module parameters).
3. Certificate Application Phase: Our engineers track approval progress with MIIT throughout the process, ensuring timely certificate issuance.

V. Documents Required for Certificate Renewal

Preparation of Documents

1. Application Form for Type Approval of Radio Transmitting Equipment: Clearly indicate the basis of Document No. 129 (MIIT Radio [2021] No. 129).

2. Letter of Request for Change from the Enterprise: Must explain the reason for the upgrade and product information (e.g., product model, specifications, and technical parameter changes related to the new standards).

3. Electronic copy of the original SRRC certificate: The original physical copy must be returned to the Ministry of Industry and Information Technology (MIIT).

4. Entrusted Testing Report:Issued by a laboratory with CMA qualification and testing capabilities compliant with Document No. 129.Note: Priority is recommended to select laboratories listed in the official qualification directory (winning bid laboratories) to ensure the report meets the new standards.

5. Basic documents:

   • Business license of the enterprise (with valid annual inspection record);
   • Power of attorney for the handler (stating the handler’s identity and scope of authority, signed and sealed by the enterprise).

6. Sample Requirements:

   • One prototype for fixed-frequency conducted testing;
   • One prototype for adaptive (interference avoidance) testing.

Conclusion: Seize Market Opportunities in the Compliance Window

With less than 3 months remaining in the 2025 new rule transition period, certification for battery-powered products has entered a "race against time." Guangdong Energy Storage Testing’s professional SRRC certification team helps you avoid certification pitfalls and quickly obtain market access qualifications.
