Lithium Battery Solutions for Modern Scanners: Powering Accuracy, Mobility, and Operational Efficiency

Industry Background

In industries such as logistics, manufacturing, retail, and field services, handheld and fixed scanners have become indispensable. From barcode and QR code scanning to RFID-enabled tracking, precision and mobility are essential. As scanners evolve toward higher processing capabilities, wireless connectivity, and longer operating shifts, the demand for reliable and compact lithium battery solutions has also increased.

The global digitalization of supply chains has accelerated the adoption of portable scanning equipment. Warehouses rely on high-frequency barcode scanners for inbound and outbound operations, retail stores depend on mobile POS systems for inventory checks, and transportation companies utilize handheld scanners for last-mile tracking. Each of these devices requires stable, lightweight, and long-lasting power to avoid downtime in busy operations.

Traditional NiMH batteries, once common in scanners, can no longer meet today’s runtime or fast-charging demands. Lithium-ion and lithium-polymer batteries have therefore become the mainstream choice due to their higher
energy density, lighter weight, and longer cycle life. Working with a professional custom battery partner like PKNERGY allows scanner OEMs to optimize both performance and cost from the beginning of the design cycle.

Pain Points in Modern Scanners

Despite technological improvements, scanning devices still face several challenges:

• High daily usage:
  Warehouse and retail environments require scanners to operate continuously for 8–12 hours or even longer in peak
  seasons.
• Peak discharge demands:
  Rapid scanning, wireless transmission, and real-time data syncing require strong pulse-current support to keep the
  device responsive.
• Compact housing:
  Scanners are becoming slimmer and more ergonomic, leaving limited internal space for the battery pack.
• Durability requirements:
  Devices must withstand drops, vibration, and frequent charging cycles without battery failure or swelling.
• Battery safety & compliance:
  Ensuring compliance with global safety standards and transportation regulations is critical for devices used and
  shipped across multiple regions.

Addressing these pain points requires not only the right cell chemistry but also a well-engineered pack, protection
circuit, and mechanical design.

Solution Value: Why PKNERGY Lithium Batteries?

PKNERGY custom lithium battery packs provide key advantages for handheld and fixed scanning devices:

• High energy density:
  Supports long runtime while keeping device weight as low as possible, improving operator comfort over long shifts.
• Pulse-current capability:
  Ensures fast, responsive scanning and stable wireless transmission performance, even under heavy usage.
• Customizable shapes:
  Soft-pack LiPo batteries and cylindrical cell packs can be tailored to fit compact scanner housings, curved grips, or
  detachable battery modules.
• Long cycle life:
  Ideal for businesses using devices daily in high-turnover environments like distribution centers and supermarkets.
• Multiple protection features:
  Built-in BMS/PCM protects against overcharge, over-discharge, over-current, short-circuit, and in many cases
  over-temperature.
• Certifications & reports:
  UN38.3, IEC62133, MSDS, and other test reports are available to support global shipment and device compliance.

Technical Insights

1. Chemistry Options

• Lithium-polymer (LiPo) for ultra-slim ergonomic scanner designs, especially where the battery must follow
  the curve of the handle or grip.
• 18650/21700 cylindrical cells for higher capacity and extended durability, suitable for industrial or
  warehouse scanners with larger housings.
• LiFePO4 for applications focusing on maximum safety and very long cycle life, such as scanners used in harsh
  industrial environments or where battery longevity is critical.

2. Electrical Parameters

• Voltage range:
  Typically a single 3.7 V cell or customized multi-cell configurations (e.g. 7.4 V, 11.1 V) depending on system design.
• Discharge performance:
  Discharge rates capable of supporting continuous scanning plus wireless data transmission without voltage drop issues.
• Fast-charging options:
  Optional fast-charging support for “quick swap-and-go” operations between shifts or during short breaks.

3. Mechanical Customization

• Slim and curved battery shapes to match scanner grip designs and keep the device comfortable to hold.
• Reinforced outer casing or customized plastic shell for impact resistance and safer drop performance.
• Flexible cable length, connector types, NTC temperature sensor, and protective circuits tailored to your PCB.

4. Safety and Reliability

• Strict cell sorting and matching from PKNERGY’s production line to ensure consistent performance.
• PCM/BMS integration according to device requirements and safety standards.
• Drop-testing, vibration-testing, and environmental testing as part of the pack validation process.
