Replacement Battery Enclosure Cover for Ultra-High Capacity Portable Radios
Maintain Sleek Structural Integrity
Secure your long-life power cells and safeguard your ultra-thin transceivers from hardware exposure.
The Motorola PMLN6745A Extended Battery Cover Door is a genuine original equipment manufacturer (OEM) replacement mechanical housing component designed specifically for slim-profile portable two-way radios. When expanding field operations with thicker, long-lasting power cells, standard factory backplates cannot enclose the increased physical dimensions. The Motorola PMLN6745A provides the precise physical depth extension necessary to enclose high-capacity power systems without causing structural gaps. It serves as an essential component for sustaining factory-spec setups utilizing Motorola CP200d Accessories and SL series components. The Motorola PMLN6745A is the updated version of the Motorola PMLN6745. The Motorola PMLN6745A is the updated version of the Motorola PMLN6745.
Engineered for discrete security networks, hotel operations coordinators, and corporate management teams, this hardline composite battery door eliminates fleet vulnerability down-times. Standard batteries keep a radio ultra-slim, but multi-shift environments require high-capacity cells that protrude from the standard rear framework. Deploying the Motorola PMLN6745A bridges this structural variation, clamping down tightly over the expanded cell block to re-establish a flush rear profile. This direct physical replacement prevents dust particles, workplace fibers, and airborne moisture film from slipping into the internal copper connection rails.
As a direct factory update, this heavy-duty plastic component replaces obsolete legacy part numbers including PMLN6745 and PMLN6001. Installation is entirely tool-less and completed in seconds by aligning the primary locking clips against the bottom edge of the transceiver frame and pressing forward until the latch locks cleanly into place. Fleet supervisors should note that this door is exclusively required for deep-profile extended cells and will sit loose if paired with shallow standard batteries.
Also fits the Motorola BT100 radio.
Key Features & Benefits
-
Extended Battery Dimension Accommodation: Precision-molded to fit perfectly around deep-profile high-capacity batteries without popping open under pressure.
-
Robust Shielding Protection: Forms a rigid barrier over the battery cell casing to protect critical gold-plated internal contacts from job-site debris.
-
Direct Authorized OEM Upgrade: Manufactured as the official, factory-spec modernization part to replace older PMLN6745 and PMLN6001 covers.
-
Tool-Free Snap Latch Mechanism: Features an optimized quick-release mechanical design for swift field battery swaps without down-time.
-
Impact-Resistant Polymer Composition: Formulated from a durable, matte-black compound that resists surface scuffs, friction wear, and drops.

Frequently Asked Questions
Can I use this specific battery door with the standard slim battery that came with my radio?
No. The Motorola PMLN6745A is specifically molded with extra depth to house thicker, high-capacity batteries like the PMNN4468. If you try to use it with a standard slim battery, the power cell will remain loose inside the housing, causing the radio to lose connection and turn off.
Does this battery cover include any rubber waterproof sealing gaskets?
This component features a hardline structural friction barrier built to match original factory enclosure parameters for slim-series portable radios. It provides solid defense against daily debris, dust ingress, and light operational contact, but it is not intended for complete underwater submersion.
Is an external tool required to remove the battery door during shift changes?
No. The cover utilizes standard integrated mechanical quick-release tabs that replicate your original radio design. You can easily remove and swap the battery door by hand during active multi-shift rotations without using tools or prying devices.
