Motorola NNTN8359CR IMPRES ATEX Li-Ion Battery

The Motorola NNTN8359CR IMPRES battery is a Li-Ion pack for operations that require documented intrinsic-safety and protection specifications alongside IMPRES battery management. It carries ATEX and IECEx intrinsic-safety ratings and a general IP67 rating, while IP64 is stated for the ATEX environment. Minimum capacity is 1800 mAh and typical capacity is 2075 mAh, with approximately 500 charge cycles listed in the supplied data. This combination establishes the battery’s distinct position within the accessory family: it supports compatible DP4401 EX and DP4801 EX radios with a defined safety and protection profile rather than acting as a generic power pack. The unit weighs 220 g and measures 135 × 54.48 × 20.8 mm. Separate typical operating times for analog and digital modes also support mode-aware deployment planning.

The field role of the Motorola NNTN8359CR IMPRES battery

The battery combines Li-Ion chemistry, IMPRES capability, and ATEX and IECEx intrinsic-safety ratings. These factors make its selection a broader matching task than choosing on capacity alone. The radio, operating environment, and documented safety requirements all matter. Supplied compatibility covers DP4401 EX and DP4801 EX, so the pack should be connected to one of those named models in deployment records. Typical operation is stated as 16 hours in analog mode and 19 hours in digital mode. Those are separate mode-specific figures and should not be combined. The two capacity figures also have distinct meanings: 1800 mAh is the stated minimum capacity, while 2075 mAh is the stated typical capacity. Inventory and procurement records should preserve those labels instead of presenting one as the other.

Protection and intrinsic-safety context

The NNTN8359CR carries a general IP67 rating, while IP64 is listed for the ATEX environment. Keeping both ratings with their stated contexts prevents one from being used as an inaccurate substitute for the other. ATEX and IECEx are the two documented intrinsic-safety ratings for this battery and are central to its operating identity. The supplied information does not specify zones, gas groups, or further approval subdivisions, so no broader scope should be inferred. When preparing a site equipment record, a team can document the battery model, compatible radio, and stated ratings, then compare that record with the operator’s approved safety requirements. This preserves the difference between a supplied product specification and the separate site decision that determines whether the complete radio configuration is authorized for a particular work area.

Saudi-sector applications

The specification set is relevant to teams in sectors where compatible communications equipment may need documented intrinsic-safety credentials, including selected energy, industrial processing, maintenance, and field-service operations. In those settings, safety or procurement staff can check ATEX and IECEx and then match the battery with a DP4401 EX or DP4801 EX before adding it to the equipment register. The IP67 rating and stated temperature limits support documentation of operating conditions, while dimensions and weight inform carry and storage planning. Organizations using analog or digital radio modes can also keep the relevant typical operating figure in their shift plan. Sector membership alone does not approve the battery for a specific location; the site’s requirements still need to be matched against the exact documented ratings without adding an unstated certification scope.

Positioning NNTN8359CR among named sibling accessories

The family includes batteries identified as HNN9008A, HNN9009A, HNN9013D, MT-777-BT, PMNN4544A, PMNN4809, and PMNN4889, together with chargers MDHTN3001, PMPN4283A, PMPN4572A, and WPLN4189A. No capacity, weight, or operating-time figure should be transferred from any sibling to the NNTN8359CR. This pack is distinguished by its own IMPRES and Li-Ion description, ATEX and IECEx ratings, IP67 protection, minimum and typical capacities, and compatibility with the named EX radios. It is a battery rather than a charger, and its documented intrinsic-safety profile differs from the radio-specific role stated for MT-777-BT. Selection should begin with compatible radio and site requirements, followed by the capacity, operating-time, and temperature specifications that belong specifically to this pack.

Capacity, operating life, and charge cycles

Minimum capacity is 1800 mAh, while typical capacity is 2075 mAh. The supplied specification lists approximately 500 charge cycles, which is an approximate figure rather than an absolute outcome under every usage condition. Typical battery life is stated as 16 hours in analog mode and 19 hours in digital mode. These figures allow a fleet manager to separate three concepts: pack capacity, approximate charge-cycle count, and typical operating time for the selected radio mode. Charging duration and operating voltage are not provided and should not be added to a comparison. IMPRES is part of the documented battery description and can be recorded when matching the pack to an appropriate management and charging arrangement, without assuming further technical details that are absent from the supplied specifications.

Dimensions, temperature limits, and deployment notes

The NNTN8359CR measures 135 × 54.48 × 20.8 mm in height, width, and depth and weighs 220 g. Its discharge temperature range is -10°C to +55°C, while the charging temperature range is 0°C to +45°C. The difference matters in deployment planning because a temperature allowed for discharge is not automatically allowed for charging. A site can place these limits in its storage, use, and charging procedure and keep charging activity within the stated range. The complete battery designation should remain visible and connected to the compatible radio and ratings record. This makes the pack a traceable component of the communications system and keeps capacity, protection, intrinsic-safety, and temperature information attached to the correct model rather than mixed with specifications belonging to another battery.
