Replacement Battery Door for TLK 100 and PMLN7932A Holster

Replace a damaged or missing rear battery cover on your Motorola WAVE TLK 100 with the genuine Motorola HKLN4678A Battery Door.

This factory replacement component securely covers the TLK 100 battery compartment while providing the correct exterior fit for use with the compatible PMLN7932A carrying holster and belt clip.

The HKLN4678A is the battery door only. The PMLN7932A holster, TLK 100 radio, battery and belt clip are not included.

Compatible Radio

• Motorola WAVE TLK 100

• Motorola WAVE TLK 100i

• Select regional equivalents using the same TLK 100 housing

This battery door is not designed for the newer Motorola TLK 110, which uses a different radio housing and replacement cover.

Compatible Carry Holster
