Motorola IMPRES™ Li-Ion Rechargeable Battery, 3200mAh, IP68, TIA4950 (PMNN4810)

From a product-positioning standpoint, PMNN4810 sits at the intersection of three priorities that matter to professional radio users: runtime, ruggedness, and safety certification. Its 3200mAh capacity targets longer operating shifts, its IP68 rating supports challenging outdoor and industrial conditions, and its ANSI/TIA-4950 intrinsically safe certification makes it relevant for users operating around flammable gases, vapors, dusts, or fibers when used in properly approved configurations.

Motorola also states that when PMNN4810 is used with IMPRES chargers, the charge cycle can increase by 43% to increase talk time, and the battery’s self-calibration feature eliminates the need to recondition the battery every 29 days. Those are significant operational advantages for fleets that depend on predictable daily charging and minimum downtime.

Design and Features

High-capacity lithium-ion construction

PMNN4810 is a lithium-ion rechargeable battery with a 3200mAh capacity. In practical terms, this positions it as a higher-end option within the R7 battery lineup, above slimmer and lower-capacity alternatives such as Motorola’s 2200mAh and 2850mAh R7 batteries. Motorola’s R7 datasheet shows that the 3200mAh PMNN4810 is grouped with the larger-format battery options intended for longer runtime.

IP68 environmental protection

The IP68 designation is a major part of the PMNN4810’s appeal. IP68-rated accessories are typically chosen for environments where dust ingress and water exposure are real concerns, such as construction sites, utilities, logistics yards, manufacturing plants, and outdoor field operations. Motorola’s official naming of the battery specifically includes IP68, confirming that rugged environmental sealing is one of its defining features.

TIA4950 intrinsically safe certification

One of the most important differentiators of PMNN4810 is its TIA4950 designation. Motorola states that the battery is certified as intrinsically safe, and the R7 datasheet further explains that ANSI/TIA 4950 and CAN/CSA C22.2 No. 157-92 certification applies for specified hazardous location classes and groups when properly equipped with a Motorola UL-approved battery. This makes PMNN4810 relevant for oil and gas, mining, chemical, energy, and industrial safety workflows.

IMPRES charging intelligence

Motorola’s IMPRES ecosystem is designed to improve battery management and charging performance. For PMNN4810, Motorola specifically claims two user-facing benefits when paired with IMPRES chargers: up to 43% longer charge cycle to increase talk time and self-calibration that removes the need for periodic manual reconditioning every 29 days. Motorola’s 2024 IMPRES self-calibration document also lists PMNN4810 among the batteries that support this functionality.

Technology and Specifications

The core specifications for PMNN4810 are established by Motorola’s official product page and the MOTOTRBO R7 datasheet:

Key specifications

• Part number: PMNN4810
• Battery type: IMPRES Li-Ion rechargeable battery
• Capacity: 3200mAh
• Protection rating: IP68
• Safety classification: TIA4950 intrinsically safe battery
• Official compatible product listed by Motorola: MOTOTRBO R7 Digital Portable Radio

Runtime and radio configuration context

Motorola’s R7 datasheet shows that the MOTOTRBO R7 with 3200mAh HAZLOC IMPRES Li-Ion Battery (PMNN4810) delivers listed battery-life figures of 29/22 hours, 28/21.5 hours, and 27.5/22 hours for different digital/analog model configurations shown in the sheet. The same datasheet lists an operating temperature of -20°C to 60°C (-4°F to 140°F) in that configuration.

Physical impact on the radio

The R7 datasheet also shows that using PMNN4810 affects the final radio size and weight. For the R7 with PMNN4810, Motorola lists dimensions of 131.8 x 56 x 40.7 mm or 131.8 x 56 x 37.3 mm, depending on model variant, and weights of 366 g or 339 g. This matters because higher-capacity batteries often involve a tradeoff between extended runtime and a slightly thicker radio profile.

Applications and Use Cases

PMNN4810 is best suited to professional users who need more than basic battery endurance.

Hazardous industrial environments

Because Motorola explicitly identifies PMNN4810 as a TIA4950 intrinsically safe battery, it is particularly relevant in environments where standard commercial batteries may not be appropriate. These include refineries, petrochemical sites, gas utilities, industrial processing facilities, mining operations, and other regulated work areas.

Long-shift operations

The 3200mAh capacity and Motorola’s published runtime figures make the battery suitable for workers covering extended shifts without convenient mid-day charging, including security teams, maintenance technicians, transportation staff, and field service crews.

Outdoor and severe-weather usage

The IP68 construction makes PMNN4810 attractive for users who regularly work around rain, washdowns, airborne dust, mud, or dirty field conditions. While the exact level of real-world resilience depends on the total radio-and-battery assembly, the battery’s IP68 designation supports deployment in tough environments.

Managed radio fleets

Organizations running fleets of MOTOTRBO R7 radios can benefit from the IMPRES charging ecosystem, especially where device uptime and battery health tracking matter. The self-calibration feature is especially useful in larger fleets because it reduces maintenance friction compared with older battery management routines.

Advantages / Benefits

Longer runtime potential

The first major benefit is simple: more operating time. Motorola positions PMNN4810 as a high-capacity 3200mAh battery, and the published R7 figures show it among the longest-runtime battery options in that family.

Intrinsically safe deployment

The second major benefit is compliance-oriented: PMNN4810 supports hazardous-location use when paired correctly with approved Motorola equipment. For many industrial buyers, that is not a luxury feature but a requirement.

Reduced battery maintenance burden

Motorola’s self-calibration claim is important because it simplifies lifecycle management. Instead of requiring regular manual reconditioning, the battery can work within the IMPRES charging system in a more automated way.

Rugged environmental durability

The IP68 rating supports use where lesser batteries or accessory combinations might be less desirable. For field users, rugged sealing contributes to confidence in harsh daily use.
