Motorola PMNN4497A High-Capacity Battery

What is the PMNN4497A?

The Motorola PMNN4497A is a Motorola Original® lithium-ion rechargeable battery for the Motorola CLS business-series two-way radios. Rated at 1,800 mAh and 3.7V, it serves as the standard replacement battery for the CLS1110 and CLS1410 radios, succeeding earlier batteries including the 56557, SNN5571, and HCNN4006. Its primary function is to restore or extend operating time for CLS-series radios in business environments requiring all-day communication.

Specifications

What's in the Box

• 1× Motorola PMNN4497A Lithium-Ion Battery

No charger or battery door is included. A compatible charger and a standard battery door are required separately. If using a high-capacity battery door for CLS radios, verify door compatibility with your specific CLS model before ordering.

Who This Product Is For

The PMNN4497A is the standard-issue replacement battery for CLS-series radios, which are widely deployed in business environments that rely on single-shift or multi-shift communication. The following industries commonly use CLS radios and routinely need replacement batteries:

• Retail — Staff on long floor shifts who need radio coverage for an entire business day without access to a charger mid-shift.
• Restaurants and food service — Teams coordinating across front-of-house, back-of-house, and delivery often run radios through double shifts; a spare battery eliminates communication downtime.
• Hospitality — Hotels, resorts, and event venues operate CLS radios across housekeeping, facilities, and front desk teams, frequently across multiple shifts per day.
• Event venues and theaters — Movie theaters, performing arts centers, and sports venues typically run CLS radios during events; a fully charged spare allows quick swaps between crews without docking a radio.
• Security — Guard teams and security coordinators on extended patrol shifts benefit from having backup batteries available to maintain continuous radio contact.
• Warehousing and light manufacturing — Facilities operating two or three shifts daily often rotate batteries rather than return radios to a charging station between uses.
• Catering and event production — Catering teams and event staff at off-site locations frequently have limited access to charging infrastructure, making a spare battery a practical operational requirement.

This battery is also appropriate for any organization that runs CLS radios across multiple shifts or needs to keep radios in active service longer than a single charge cycle allows. Buying replacement batteries in quantities matched to radio fleet size is a common practice for facilities managers and IT/communications coordinators managing CLS deployments.

Frequently Asked Questions

What radios is the Motorola PMNN4497A compatible with?

The PMNN4497A is compatible with Motorola CLS-series and VL-series business two-way radios, specifically the CLS1110 and CLS1410. It is not compatible with Motorola CLP-series, CLPe-series, CP-series, or DTR-series radios. If you are unsure which battery your radio requires, check the label on your existing battery or consult the radio's user guide.

What older Motorola battery does the PMNN4497A replace?

The PMNN4497A is the current Motorola Original® replacement for several earlier CLS-series batteries, including the Motorola 56557, BAT56557, SNN5571, SNN5571B, HCNN4006, and HCNN4006A. These older part numbers were the factory-included batteries in earlier CLS radio production runs. The PMNN4497A is a drop-in physical replacement for all of them.

How long does the PMNN4497A battery last on a single charge?

Motorola rates the PMNN4497A for up to 15 to 18 hours of operation per charge. Actual operating time depends on the radio's duty cycle — the ratio of time spent transmitting, receiving, and in standby. Heavier transmit usage reduces battery life. Under a standard business-radio duty cycle (5% transmit, 5% receive, 90% standby), the battery is designed to cover a full work shift without requiring a mid-shift charge.

Does the PMNN4497A work with my existing CLS charger?

Yes. The PMNN4497A is compatible with Motorola's standard CLS-series single-unit and multi-unit chargers, including the Motorola PMPN4529A drop-in tray charger. The battery uses the same physical form factor and contacts as the batteries that originally shipped with CLS radios, so it charges correctly in any standard CLS charging cradle without modification.

Do I need a different battery door when using the PMNN4497A?

The PMNN4497A uses the same standard battery door that ships with CLS1110 and CLS1410 radios. No special high-capacity door is required for this battery, as it is the same size as the original CLS battery. If you are purchasing a separately marketed "high-capacity" aftermarket battery of greater capacity, that may require a different door — but the OEM PMNN4497A does not.

Is the Motorola PMNN4497A a Motorola genuine part or an aftermarket battery?

The PMNN4497A sold by techwholesale.com is a Motorola Original® (OEM) battery, manufactured to Motorola's specifications under Motorola quality controls. It carries a 12-month Motorola manufacturer warranty. Aftermarket third-party batteries that cross-reference the PMNN4497A part number are also sold by other suppliers, but those are not covered under Motorola's warranty and may have different capacity ratings, materials, or quality standards. When ordering, confirm the product is labeled as a Motorola Original® or Motorola Genuine part.

How many replacement batteries should I buy for a fleet of CLS radios?

A common approach for facilities running CLS radios across a single daily shift is to have one spare battery per radio, allowing one to charge while the other is in use. Organizations running two or more shifts back-to-back often maintain two spare batteries per radio to ensure each shift starts with a fully charged unit. For high-use environments where radios are in continuous operation, having batteries rotate through a multi-unit charger throughout the day is typical practice.
