Application Background
This battery solution is specially designed for mobile printing devices, including handheld label printers, receipt printers, and field ticket printing equipment.
These devices are typically used in mobile or outdoor environments and require long-duration continuous operation. Frequent switching between printing and standby modes places high demands on battery runtime, output stability, and compact structural design.
Project Challenges
- Long continuous printing requires high battery endurance
- High instantaneous load during printing may cause voltage drops or shutdown
- Frequent charge–discharge cycles demand strong cycle stability
- Limited internal space requires strict control of size and weight
- Harsh environments require higher reliability and stability
Customized Battery Solution
- 18650 1S2P configuration: 5200mAh capacity for extended runtime at 3.7V platform
- 5A peak discharge capability: ensures stable output during printing load peaks
- ABS+PC housing: flame-retardant and impact-resistant design for higher safety
- Multiple protection system: overcharge, over-discharge, overcurrent, and short-circuit protection
- Wide temperature design: supports -20°C to 60°C discharge for outdoor and complex environments
Application Results
- Significantly extends device runtime for long-duration mobile operations
- Stable output under high-load printing, reducing shutdown risk
- Flame-retardant structure improves overall safety and reliability
- Lightweight design enhances handheld comfort and usability
- Improved overall stability and longer service life of the device
