Which Battery Is Best for the PMPN4604?

Choose the NNTN9216 for standard APX NEXT use in non-HAZLOC environments.

Choose the NNTN9217 when the APX NEXT configuration requires a compatible UL Division 2 battery.

Choose the NNTN9089, NNTN9090, PMNN4895 or PMNN4896 when maximum APX NEXT runtime is more important than minimum size and weight.

Choose the PMNN4816 for routine APX N70 use and a more compact battery profile.

Choose the PMNN4817 for APX N70 users requiring maximum available capacity for long shifts.

Choose the PMNN4818 when an approved safety-rated APX N70 battery is required.

Motorola IMPRES 2 Charging Technology

IMPRES 2 is Motorola’s intelligent battery-charging and management system. The PMPN4604 communicates with compatible Motorola IMPRES batteries and automatically adjusts charging according to battery condition, temperature, usage history and remaining capacity.

IMPRES 2 benefits include:

• Up to 3-amp fast charging

• Automatic recognition of compatible IMPRES batteries

• Automated battery calibration

• Optimized charging for standard- and high-capacity batteries

• More accurate radio battery-gauge information

• Reduced need for manual battery maintenance

• Support for battery self-calibration

• Improved long-term battery management

• Charging with the battery alone or attached to the radio

Actual charging time and battery life depend on battery capacity, age, condition, temperature, radio settings and usage.

PMPN4604 Charging Time

The PMPN4604 can provide up to 3 amps of charging current. Exact charging time depends on:

• Battery capacity

• Remaining battery charge

• Battery age and condition

• Battery temperature

• Whether calibration is required

• Whether the radio is operating while charging

A partially discharged standard-capacity battery generally charges faster than a completely depleted high-capacity battery. An IMPRES calibration cycle will also take longer than a normal charging cycle.

For the fastest and most consistent charging results, turn the radio off before placing it in the charger.

Charging a Battery Alone or Attached to the Radio

The PMPN4604 offers two convenient charging methods:

Charge the Radio and Battery Together

Place a compatible radio with its battery installed directly into the charging pocket. This is the most convenient option for daily charging after a shift.

Charge a Spare Battery

A compatible battery can be placed directly into the charger without being attached to the radio. This allows users to operate the radio with one battery while charging a spare.

PMPN4604A vs PMPN4604B

PMPN4604 is the base product number. PMPN4604A and PMPN4604B identify Motorola manufacturing or product revisions.

Both revisions are associated with the IMPRES 2 single-unit fast-charging platform. However, buyers should confirm the supplied revision, power supply and radio compatibility when purchasing replacement, open-box or used equipment.

Unless a specific revision is required by an agency contract or equipment standard, the current Motorola-supplied revision is generally the appropriate choice.

PMPN4604 vs NNTN9199

The PMPN4604 and NNTN9199 are both Motorola IMPRES 2 single-unit chargers for compatible APX NEXT batteries.

Choose the PMPN4604 when charging both APX NEXT and APX N70 platforms is important.

Choose the Motorola NNTN9199 for a dedicated APX NEXT single-unit charging installation.

PMPN4604 vs PMPN4591

The PMPN4604 charges one radio or battery, while the PMPN4591 supports a shared fleet.

Choose the PMPN4604 for an individual desk, office or home. Choose the Motorola PMPN4591 six-unit charger when multiple radios must be charged in one location.

PMPN4604 vs NNTN9115

The PMPN4604 is intended for one user, while the NNTN9115 provides six charging positions and six information displays.

The Motorola NNTN9115 is a better option for departments that need to charge several APX NEXT radios together.

Replacement Power Supply Options

Common power-supply references associated with the PMPN4604 charging platform include:

• Motorola PS000040A01

• Motorola PS000040A02

• Motorola PS000116A01

The correct power supply depends on the charger revision, input-voltage requirements and whether a separate AC power cord is required.

Do not order a replacement power supply based only on connector appearance. Confirm the exact charger revision and electrical specifications first.

Accessory compatibility depends on the radio model, battery thickness, firmware and required safety classification.

Is the PMPN4604 HAZLOC Approved?

The PMPN4604 should not be operated in a hazardous atmosphere unless the charging equipment and location are specifically approved for that use.

The charger can charge compatible safety-rated batteries, including selected NNTN9217, NNTN9088, NNTN9090, PMNN4812, PMNN4818 and PMNN4896 revisions. However, charging a safety-rated battery does not make the charger itself HAZLOC certified.

Safety-rated batteries should be charged in a designated non-hazardous area according to agency procedures and applicable safety requirements.
