Advantages and Features MOTOROLA PMNN4489A

  1. Intrinsic Safety: MOTOROLA PMNN4489A’s TIA4950/UL certification ensures safe operation in explosive zones, eliminating the risk of spark – induced ignition in oil refineries, chemical plants, or mining sites.
  2. Smart IMPRES Technology: MOTOROLA PMNN4489A tracks cycle life, state – of – health, and charge history via IMPRES software, enabling proactive fleet maintenance and reducing unexpected battery failures.
  3. Extended Runtime: MOTOROLA PMNN4489A’s 2900mAh capacity delivers 25–27 hours of use, supporting 12+ hour shifts without recharging for utility linemen, firefighters, or plant operators.
  4. Harsh Environment Durability: MOTOROLA PMNN4489A’s IP68 rating ensures reliable performance in dusty, wet, or high – vibration settings, withstanding outdoor and industrial abuse.
  5. Broad Compatibility: MOTOROLA PMNN4489A works with 20+ Motorola portable radio models, maximizing investment by fitting existing and new fleet radios.

Application Cases MOTOROLA PMNN4489A

  1. Oil Refinery Communication: A major oil company deployed MOTOROLA PMNN4489A in its offshore refinery radio fleet. Its intrinsic safety and IP68 rating allowed safe use in Zone 1 hazardous areas, and 27 – hour runtime cut shift – change battery swaps by 75%, improving worker safety and operational efficiency.
  2. Wildland Firefighting: A fire department used MOTOROLA PMNN4489A with APX3000 radios. Its IP68 waterproofing survived rain/flood exposure, and IMPRES tracking let the department replace aging batteries proactively, reducing radio downtime by 40% during wildfire responses.
  3. Mining Operations: A mining firm integrated MOTOROLA PMNN4489A into its underground radio system. Its intrinsic safety and extended runtime kept teams connected for 14 – hour shifts, while dust/water resistance prevented failures in harsh mining conditions.

Selection Suggestions

  1. Choose MOTOROLA PMNN4489A for Motorola MotoTRBO e Series, APX, or DGP radios used in hazardous locations (oil, gas, mining), prioritizing its TIA4950/UL intrinsic safety and IMPRES tracking.
  2. Prioritize MOTOROLA PMNN4489A for 12+ hour shift operations, leveraging its 2900mAh capacity and 27 – hour runtime to avoid mid – shift recharges.
  3. Select MOTOROLA PMNN4489A if you use IMPRES fleet management software, as its smart data tracking reduces maintenance costs and extends battery life.

Precautions

  1. Use only Motorola IMPRES – certified chargers with MOTOROLA PMNN4489A to maintain safety, runtime, and IMPRES functionality; avoid generic chargers that void warranties.
  2. Do not expose MOTOROLA PMNN4489A to temperatures beyond -20°C to +60°C, as extreme heat/cold degrades capacity and lifespan.
  3. Replace MOTOROLA PMNN4489A after 500 charge cycles or when IMPRES software flags “end – of – life” to ensure reliable performance in critical operations.
  4. Store MOTOROLA PMNN4489A at 40%–60% charge in a cool (15°C–25°C), dry place when not in use for long periods.
  5. Do not disassemble or puncture MOTOROLA PMNN4489A, as this risks fire/explosion; dispose of via certified e – waste recyclers.
