GB/T 18287 Cycle Life Testing of Lithium-Ion Batteries for Mobile Phones
The GB/T 18287 standard specifies the cycle life test method for lithium-ion batteries used in mobile phones. This testing procedure is critical to ensure that batteries meet the stringent requirements set forth by regulatory bodies and industry standards. The test evaluates how many charge-discharge cycles a battery can undergo before its performance degrades beyond acceptable limits. This section will delve into the intricacies of this test, its importance for quality managers, compliance officers, R&D engineers, and procurement professionals.
Compliance with GB/T 18287 is mandatory in China, ensuring that batteries used in mobile phones are reliable and safe over extended periods. This standard not only addresses the chemical and physical properties of lithium-ion cells but also their electrical performance during cyclic operation. The test helps manufacturers identify potential weaknesses early on, allowing for improvements before product release.
The cycle life testing process involves subjecting batteries to a series of charge-discharge cycles under controlled conditions. These conditions include specific temperature ranges, voltage limits, and current rates tailored to simulate real-world usage scenarios. By adhering strictly to these parameters, testers can accurately assess the battery's durability without affecting its safety or reliability.
The importance of this testing cannot be overstated in today’s fast-paced technological environment where consumer expectations for product longevity are higher than ever before. Non-compliance could lead to recalls, financial losses, and damage to brand reputation. Thus, it is essential for manufacturers to invest in robust testing facilities and methodologies like those provided by our laboratory.
Our state-of-the-art laboratory uses cutting-edge equipment capable of replicating various environmental stresses that batteries might encounter during their lifecycle.

| Aspect | Description |
|---|---|
| Test Setup | The setup includes a test chamber capable of maintaining precise temperature and humidity levels, as well as an automated charging-discharging system. |
| Environmental Factors | Batteries are subjected to temperatures ranging from -20°C to +65°C with relative humidity up to 98% RH. |
| Charging and Discharging Cycles | The batteries undergo a series of charge-discharge cycles, each cycle consisting of charging at 1C until full capacity is reached followed by discharging at the same rate until voltage drops below threshold. |
Our team of experienced professionals employs advanced software tools to monitor and record every aspect of the testing process. This ensures accurate data collection, which forms the basis for detailed reports delivered promptly after completion of each cycle. These reports provide valuable insights into any performance issues that may arise during testing.
In conclusion, compliance with GB/T 18287 is not just about meeting regulatory requirements but also about delivering superior products to consumers. By investing in thorough cycle life testing, manufacturers can enhance their brand value and customer satisfaction while reducing potential risks associated with faulty batteries.
Why It Matters
- Battery durability directly impacts user experience and satisfaction.
- Meeting regulatory standards enhances product reliability and safety.
