Industry Background

Laser distance meters have become essential tools across construction, interior design,
surveying, smart home installation, and outdoor measurement. As devices become smarter—
integrating OLED displays, Bluetooth data synchronization, continuous measurement modes,
and advanced processors—their performance increasingly depends on one critical component:
the battery.

Modern laser distance meters require far more power than traditional AAA or coin-cell designs.
Typical power-consuming features include:

• High-power laser emission
• Continuous distance calculation
• Bright backlit displays
• Bluetooth wireless transmission
• Built-in computing and memory
• Vibration or beeper feedback

To meet these demands, manufacturers now rely on rechargeable lithium batteries—
most commonly 14500, lithium polymer, or 18650 cells—depending on product structure
and target runtime.

Pain Points in Today’s Laser Distance Meters

1. High instantaneous current causes voltage drop

When the laser is triggered, current spikes occur. Low-grade cells with high internal
resistance cannot handle the load, leading to screen flicker, laser failure, or sudden shutdown.

PKNERGY Advantage:

• Low-internal-resistance Grade-A cells
• Stable laser startup under high load
• No “press but cannot measure” failures

2. Continuous measurement mode drains power quickly

Continuous measurement keeps the laser active while refreshing the display and transmitting
data. Weak batteries often collapse within minutes.

PKNERGY Advantage:

• High-discharge 14500 / 18650 cells
• 1–2 hours stable continuous measurement
• No voltage sag or device lag

3. False capacity claims lead to unrealistic runtime

Many low-cost meters advertise exaggerated capacities, yet internally use recycled or
low-capacity cells—resulting in poor real-world runtime.

PKNERGY Advantage:

• Honest capacity ratings
• Verification reports available
• 100% new, consistent cells

4. Harsh field conditions require industrial-grade batteries

Laser meters are often used outdoors and on construction sites, where temperature variation
and vibration are common.

PKNERGY Advantage:

• Reliable operation from –20°C to 60°C
• Vibration-resistant assembly options
• Optional epoxy reinforcement and protective coating

5. Limited internal space requires flexible battery formats

Internal space is constrained by the laser module, motherboard, display, and housing,
leaving little room for batteries.

PKNERGY Advantage:

• Standard 14500 and 18650 cylindrical cells
• Custom lithium-polymer pouch shapes
• Tailored dimensions for OEM designs

Conclusion — Precision Comes From Algorithms, Reliability Comes From the Battery

A laser distance meter may have advanced sensors and algorithms, but without a reliable
battery it will inevitably suffer from weak laser output, flickering displays, fast power
drain, and shortened lifespan.

Leading manufacturers are upgrading their power systems—and PKNERGY provides the
industrial-grade lithium battery solutions required for true reliability, stability,
and long-term performance.
