1. Introduction

In industrial safety, mining, and environmental monitoring, portable dust monitors play a key role in assessing particulate matter (PM2.5, PM10) exposure in workplaces and cities. These instruments increasingly rely on custom lithium battery packs that deliver longer runtime, lighter weight, and superior durability for field use.

2. Why Lithium Battery for Dust Monitors

Older dust monitors powered by NiMH or alkaline batteries suffer from short runtime and bulky design. In contrast, lithium-ion batteries offer multiple advantages:

• High energy density — supports 12+ hours continuous operation
• Lightweight for handheld or wearable applications
• Stable voltage output ensuring sensor precision and fan performance
• Longer lifespan and faster charging efficiency

3. Key Customization Requirements

• Voltage & Capacity: 3.7V / 7.4V configurations, 2,000–6,000mAh
• Safety: Certified to UN38.3 & IEC62133, with short-circuit, overcharge, and temperature protections
• Shape & Mounting: Slim rectangular or cylindrical designs for compact housings
• Temperature Range: –20°C to +60°C, suitable for outdoor environments
• Service Life: 1,000+ cycles, optimized for “charge once per shift” operation

4. Use Case Example
