Factory testing procedures for telecom lithium batteries in China are essential to guarantee reliability in mission-critical applications. These rigorous protocols detect defects early, minimize downtime, and comply with national standards, delivering batteries that power base stations without interruption.
What Challenges Does the Telecom Lithium Battery Industry Face in China Today?
China’s telecom sector relies heavily on lithium batteries for backup power, yet demand fluctuations create pressure. Projections indicate lithium battery shipments will reach 1500 GWh by 2026, with energy storage batteries comprising 25% of the market, but early 2026 sees a sharp drop due to a 30% decline in related sectors like EVs.
This volatility exposes manufacturers to overproduction risks, where excess capacity leads to rushed testing and quality compromises. Telecom operators report up to 15% of batteries failing prematurely under high-temperature conditions common in China, amplifying operational costs.

Pain points intensify with regulatory scrutiny; non-compliant batteries face recalls, costing millions. Industry data shows 20% of telecom outages stem from battery failures, underscoring the urgent need for robust factory testing to avert widespread disruptions.
Why Do Traditional Testing Methods Fall Short for Telecom Lithium Batteries?
Traditional manual inspections often miss micro-defects like internal shorts, relying on visual checks that detect only 60-70% of issues. These methods lack scalability for high-volume production, leading to inconsistent results across batches.

Spot-testing samples instead of 100% screening saves time but risks shipping faulty units, with failure rates climbing to 5-10% in field deployments. Older equipment struggles with modern LiFePO4 chemistries, failing to simulate real-world telecom stresses like 55°C heat and deep discharge cycles.
Comparisons reveal traditional approaches increase lifecycle costs by 25%, as undetected flaws cause premature replacements. They also lag in data traceability, complicating audits under China’s GB/T 36276 standard.
