Motorola SL7550 Common Replacement Accessories Buying Guide: Batteries, Belt Clips, Chargers and More

The Motorola SL7550 is a slim, professional MOTOTRBO™ portable two-way radio designed for users who need reliable communication in a compact form factor. Its thin profile and full keypad make it suitable for security teams, hotels, retail stores, property management, transportation, education, and other commercial environments.

Like any radio used every day, the SL7550's accessories can eventually wear out. Batteries lose capacity after repeated charging cycles, belt clips can break, antennas may become damaged, and charging or audio accessories may need replacement.

For companies that already own an SL7550 fleet, replacing individual accessories can be a practical way to extend the service life of working radios. For two-way radio repair shops, used-radio dealers, distributors, and accessory resellers, commonly requested SL7550 parts can also be useful products to keep in stock.

This guide covers the major Motorola SL7550 replacement accessories, including batteries, battery covers, carry holders, chargers, antennas, earpieces, screen protectors, and programming cables.

Note: The SL7550 is a discontinued radio model, so accessory availability can vary by region and supplier. Always verify the exact radio version, battery type, frequency band, and part number before purchasing.

Motorola SL7550 Replacement Accessories List

Here is a practical list of the main SL7550 accessories that repair shops and distributors may want to stock:

Motorola's official SL7550 documentation lists multiple battery, antenna, audio, carry, and programming accessories, including PMNN4468, HKNN4013, PMNN4425, PMLN5956, PMLN6074, PMLN7040, and PMKN4128.

1. Motorola SL7550 Replacement Battery

The battery is one of the most important replacement accessories for an SL7550 radio.

Motorola's SL7550 documentation lists three main Li-Ion battery options:

· PMNN4468 / PMNN4468A — 2300 mAh BT100x battery

· HKNN4013 / HKNN4013A — 1800 mAh BT90 battery

· PMNN4425 / PMNN4425B — 1400 mAh BT7X battery

These battery options give users different choices depending on operating time, weight, and radio configuration.

PMNN4468 2300 mAh Battery

The PMNN4468 is one of the most important SL7550 replacement batteries to consider. It provides higher capacity than the standard 1400 mAh option and is useful for users who need longer operating time.

Typical applications include:

· Security patrols

· Hotel operations

· Warehouses

· Transportation

· Retail

· Property management

Current accessory listings also identify PMNN4468 as a 2300 mAh battery used with the SL7550/SL7550e family.

HKNN4013 1800 mAh Battery

The HKNN4013 is an 1800 mAh Li-Ion battery. It can be considered when users want a balance between battery capacity and overall radio weight.

PMNN4425 1400 mAh Battery

The PMNN4425 is the 1400 mAh Li-Ion battery option.

For customers who use the radio for shorter shifts or want a lighter configuration, this battery may be appropriate.

2. How to Choose the Correct SL7550 Battery?

When buying an SL7550 replacement battery, do not choose solely according to the mAh number.

Check:

1. Battery model 

2. Battery physical dimensions 

3. Battery cover compatibility 

4. Radio frequency version 

5. Required operating time 

6. Replacement battery quality 

The battery cover is particularly important because the different battery capacities may use different covers.

For example, the PMLN6745/PMLN6745A is associated with the BT100x high-capacity battery, while PMLN6001/PMLN6001A and PMLN6000/PMLN6000A correspond to other battery configurations.

For repair shops, stocking the battery together with the corresponding battery cover can make replacement work much easier.

3. Motorola SL7550 Battery Covers

Battery covers are small components but are frequently damaged during repeated battery changes.

The main SL7550 battery covers include:

PMLN6745 / PMLN6745A

Designed for the BT100x 2300 mAh battery configuration.

PMLN6001 / PMLN6001A

Designed for the BT90 1800 mAh battery configuration.

PMLN6000 / PMLN6000A

Designed for the BT7X standard battery configuration.

These replacement covers are particularly useful for radio repair businesses because a cracked or missing battery cover does not necessarily mean the radio itself needs replacement.

4. Motorola SL7550 Belt Clip and Carrying Accessories

A professional radio is frequently attached to a belt or carried throughout a work shift, so the carry accessory is exposed to considerable mechanical stress.

For the SL7550, the PMLN5956 Swivel Carry Holder is an important replacement carry accessory. Motorola describes it as a lightweight carry holder designed for SL Series radios.

The PMLN5956 can be useful for:

· Security personnel

· Hotel staff

· Retail workers

· Maintenance teams

· Property management

· Event staff

The swivel design allows the radio to move with the user while remaining attached to the belt.

Why Stock SL7550 Carry Holders?

For repair shops and distributors, carry accessories are attractive inventory items because they:

· Take up little storage space

· Are easy to ship

· Are simple to replace

· Frequently experience physical wear

Replacing a damaged carry holder is also much less expensive than replacing a functional radio.

5. Motorola SL7550 Nylon Wrist Strap

The PMLN6074 is a nylon wrist strap listed among the SL7550 carry accessories.

A wrist strap can provide additional security when users frequently handle the radio.

It can be useful in:

· Warehouses

· Manufacturing

· Maintenance

· Transportation

· Outdoor operations

For distributors, wrist straps can be a useful add-on product when selling batteries, cases, or other SL7550 accessories.

6. Motorola SL7550 Leather Carry Case

For customers who want additional protection, the PMLN7040/PMLN7040A soft leather carry case provides an alternative to the standard carry holder.

The case features a 1.5-inch quick-release swivel clip and is listed for the SL7550/SL7550e family.

A protective carry case can be particularly useful for:

· Security companies

· Hospitality businesses

· Professional service teams

· Transportation companies

It can help protect the radio body from scratches and everyday wear.

7. Motorola SL7550 Screen Protector

The SL7550 includes a display and keypad, so protecting the screen can be useful for heavily used radios.

The AY000269A01 is listed as a clear screen protector for the SL7550e family.

For used-radio dealers and refurbishment businesses, a new screen protector can also help improve the appearance of a refurbished radio.

This is a relatively inexpensive accessory that can be added during refurbishment.

8. Motorola SL7550 Charger Replacement

A reliable charger is essential for keeping a radio fleet operational.

The SL7550 accessory ecosystem includes several charging options.

PMPN4009B/PMLN7094A Single-Unit Rapid Charger

The PMPN4009B/PMLN7094A is a  single-unit rapid charger listed for the SL7550e family.

It is suitable for:

· Individual radio users

· Small businesses

· Retail stores

· Small security teams

PMLN6701A Tri-Unit Charger

The PMLN6701A is a tri-unit rapid charger designed to simultaneously charge a radio, spare battery, and Bluetooth device.

For professional users, this can be more convenient than maintaining several individual chargers.

PMLN6687A Six-Pocket Charger

The PMLN6687A is a six-pocket rapid-rate charger designed for larger radio fleets.

It can be particularly useful for:

· Security companies

· Hotels

· Warehouses

· Factories

· Transportation companies

For a business operating multiple SL7550 radios, centralized charging can simplify daily fleet management.

9. Motorola SL7550 Antenna Replacement Guide

Antenna selection is another important part of SL7550 maintenance.

Motorola's SL7550 documentation lists antenna options for different frequency bands, including UHF and 800/900 MHz configurations.

UHF Antenna Options

Common UHF antenna part numbers include:

· PMAE4076 — 420–445 MHz

· PMAE4077 — 438–470 MHz

· PMAE4078 — 403–425 MHz

· PMAE4091 — 450–490 MHz

· PMAE4092 — 480–527 MHz

800/900 MHz Antennas

The official accessory list also includes:

· PMAF4017 — 806–870 MHz

· PMAF4018 — 896–941 MHz

How to Select an SL7550 Antenna

Always verify the actual radio frequency before purchasing.

Do not select an antenna simply because the connector or physical appearance looks correct.

Check:

· Frequency band

· Frequency range

· Antenna part number

· Radio configuration

· Required antenna length

For distributors, keeping several popular UHF antenna ranges in inventory can make it easier to support different SL7550 customers.

10. Motorola SL7550 Earpieces and Audio Accessories

The SL7550 is widely used in environments where hands-free or discreet communication is important.

Motorola's official SL7550 accessory information includes several audio options.

PMLN7159 Adjustable D-Style Earpiece

The PMLN7159 is an adjustable D-style earpiece designed for SL Series radios.

It provides a secure over-ear design and can be useful for:

· Security

· Hospitality

· Retail

· Events

PMLN7158 Surveillance Earpiece

The PMLN7158 is a one-wire surveillance earpiece with inline microphone and PTT.

Motorola's compatibility information specifically lists SL7550 and SL7550E among compatible radios.

This makes it especially relevant for security companies and other users who require discreet communication.

PMLN7203 Flexible Earpiece

The PMLN7203 flexible earpiece with boom microphone is another audio option listed for the SL Series.

PMLN7851A Bluetooth PTT Earpiece

For customers looking for wireless communication, the PMLN7851A is a Bluetooth PTT earpiece listed in Motorola's SL7550 accessory range.

11. Motorola SL7550 Programming Cable

For radio repair shops, programming accessories can be just as important as physical replacement parts.

The PMKN4128 Micro USB Programming Cable is listed in Motorola's SL7550 accessory documentation.

It can be useful for:

· Radio technicians

· Repair shops

· Radio dealers

· Fleet managers

When purchasing programming accessories, make sure the cable is intended for the exact radio series and software environment being used.

12. Recommended SL7550 Inventory for Repair Shops

If you operate a Motorola radio repair shop, used-radio business, or accessory distribution company, the following products are worth considering:

This inventory covers the major battery, charging, carrying, antenna, audio, and maintenance accessory categories for the SL7550.

Why Choose Compatible Motorola SL7550 Accessories?

For companies with an existing SL7550 fleet, compatible replacement accessories can provide a practical way to reduce maintenance costs.

Instead of replacing an entire radio because of a worn battery, damaged carry holder, broken battery cover, or damaged antenna, users can replace the individual component.

This approach can help:

Reduce Equipment Costs

Replacing individual parts is generally more economical than replacing a complete radio.

Extend Radio Service Life

New batteries, carry accessories, antennas, and audio accessories can keep existing radios useful for longer.

Reduce Downtime

Repair shops can complete simple accessory replacements faster when popular parts are already in stock.

Support Used and Refurbished Radios

For used-radio dealers, replacing worn accessories can improve the appearance and usability of refurbished SL7550 units.

Final Thoughts

The Motorola SL7550 remains a useful professional two-way radio for organizations that already operate SL Series equipment. Although the radio itself has been discontinued, many businesses continue to maintain existing units rather than replace an entire fleet.

The most important SL7550 replacement accessories include the PMNN4468/PMNN4468A 2300 mAh battery, HKNN4013 1800 mAh battery, PMNN4425 1400 mAh battery, PMLN6745 battery cover, PMLN5956 carry holder, PMLN7040 leather case, PMPN4009B charger, PMLN6701A tri-unit charger, PMLN6687A six-pocket charger, PMAE-series antennas, PMLN7159/PMLN7158 earpieces, and PMKN4128 programming cable.

When selecting an accessory, the most important factors are part number, battery configuration, frequency range, physical compatibility, and intended application.

For repair shops, distributors, and businesses searching for Motorola SL7550 replacement batteries, chargers, antennas, carry accessories, earpieces, or other compatible Motorola parts, maintaining a focused inventory of frequently requested items can make radio maintenance faster and more cost-effective.

With the right replacement accessories, businesses can extend the useful life of their existing SL7550 radios and avoid unnecessary equipment replacement.
