Maintenance and Battery Tips for Long-Term Thermal Binocular Performance

The Importance of Proper Care

Thermal binoculars are precision instruments—combining sensitive electronics, optical coatings, and AI-enhanced imaging systems into one rugged device. With the right maintenance routine, you can keep your ATN BINOX 6 DUAL operating at peak performance for years.

Unlike conventional optics, thermal systems require a balance of cleanliness, care, and power management. The following guide outlines best practices for maintaining image clarity, preserving battery health, and ensuring long-term reliability in the field.

1. Cleaning the Lenses and Sensor Housing

Use the Right Tools

  • Microfiber Cloth or Lens Tissue: Always use a clean, lint-free cloth to wipe lenses.

  • Lens Cleaning Solution: Use only optical-grade solution designed for germanium or coated lenses. Avoid alcohol or ammonia-based cleaners—they can damage coatings.

  • Lens Brush or Air Blower: Gently remove dust and debris before wiping to prevent scratches.

Cleaning Procedure

  1. Remove surface dust using a soft blower or brush.

  2. Moisten the microfiber cloth with cleaning solution—never apply liquid directly to the lens.

  3. Wipe in gentle circular motions from the center outward.

  4. Allow the lens to air dry before storing the device.

Why It Matters

The BINOX 6 DUAL uses high-transmission germanium lenses. These lenses are durable but sensitive to scratches and contaminants, which can scatter infrared light and reduce clarity. Keeping them clean ensures the SharpIR® AI engine receives the purest possible signal.

2. Protecting the Housing and Electronics

General Handling

  • Always store your device in the protective bag or case provided.

  • Avoid dropping, bumping, or over-tightening tripod mounts.

  • Do not expose the binoculars to direct heat sources (like car dashboards or heaters).

Environmental Protection

The BINOX 6 DUAL is IP67-rated, meaning it’s waterproof and dustproof. However, you should:

  • Rinse gently with fresh water after exposure to salt or dust.

  • Dry thoroughly before charging or opening any ports.

  • Keep port covers securely closed during field operations.

Storage Conditions

  • Temperature Range: Store between -10°C and +40°C (14°F to 104°F).

  • Humidity: Keep below 60% relative humidity for long-term storage.

  • Position: Store flat or upright, never under heavy weight or pressure.

3. Battery Maintenance and Power Management

Understanding the Power System

The ATN BINOX 6 DUAL runs on two replaceable 18650 rechargeable batteries, delivering up to 8 hours of continuous use. Proper care of these batteries ensures consistent performance and extended lifespan.

Charging Best Practices

  • Use the supplied 18650 charger or a high-quality compatible charger.

  • Charge before first use and after long periods of storage.

  • Avoid leaving batteries on charge overnight or unattended.

  • Charge at room temperature (10°C–30°C / 50°F–86°F).

Storage and Longevity

  • Store batteries at 50–70% charge if the device will be unused for more than a month.

  • Recharge every 2–3 months to prevent deep discharge.

  • Do not expose batteries to moisture, direct sunlight, or freezing temperatures.

External Power Options

The BINOX 6 supports USB-C external power for extended missions. Connecting a power bank ensures uninterrupted use during long hunts, surveillance, or multi-day expeditions.

When using external power:

  • Ensure cables are fully seated and protected from tension or water exposure.

  • Disconnect external power during rain or when storing the device.

4. Software and Firmware Maintenance

Keep Firmware Updated

ATN regularly releases firmware updates to enhance stability, SharpIR® performance, and app connectivity.

  • Connect the device to the ATN Connect 6 app to check for updates.

  • Follow on-screen instructions for installation—never power off during the process.

Regular Calibration

Thermal sensors perform best when periodically recalibrated:

  • Access Calibration Mode in the settings menu.

  • Choose Auto for continuous self-adjustment or Manual when precision tuning is required in extreme environments.

Calibration removes image drift, aligns temperature readings, and ensures consistent clarity across sessions.

5. Handling After Exposure to Extreme Conditions

Cold Weather Operation

  • In freezing environments, battery efficiency may drop. Keep a spare pair of 18650 batteries inside your jacket to stay warm.

  • Avoid rapid transitions from cold to warm environments to prevent condensation on internal optics.

Heat and Humidity

  • In hot or tropical climates, use silica gel packs inside the carrying case to control moisture.

  • Avoid storing in direct sunlight to protect electronic components and screen contrast.

Rain and Saltwater

The BINOX 6’s IP67 housing resists rain and temporary submersion, but salt residue can degrade seals. After marine use, rinse gently with fresh water and dry completely before storage.

6. Common Mistakes to Avoid

  • Overcleaning the Lens: Excessive cleaning may wear coatings—only clean when visibly dirty.

  • Using Incorrect Chargers: Always use approved chargers to prevent overvoltage damage.

  • Leaving Batteries Inside Long-Term: Remove batteries when storing the device for months to avoid corrosion.

  • Ignoring Firmware Updates: Outdated software can reduce SharpIR® efficiency or app compatibility.

  • Operating with Wet Ports: Moisture inside USB-C or battery compartments can short circuits.

7. Long-Term Care and Professional Service

Even the most durable systems benefit from occasional professional maintenance. ATN recommends:

  • Annual inspection of seals, ports, and optical alignment.

  • Replacement of worn batteries every 2–3 years depending on usage.

  • Factory recalibration if thermal imaging becomes inconsistent or degraded.

Conclusion: Protect the Vision That Protects You

Thermal binoculars are an investment in precision and awareness. By maintaining your ATN BINOX 6 DUAL with proper cleaning, calibration, and battery care, you ensure it performs flawlessly when it matters most.

Durability begins with routine discipline. Keep lenses clean, power systems healthy, and firmware up to date—and your device will deliver years of uncompromised clarity and reliability in every mission.
