Genuine Motorola Solutions Original replacement rear battery compartment door designed to restore secure retention and IP67 environmental sealing on LEX L10 LTE handhelds.
The Motorola HKLN4619A (also cataloged as HKLN4619) is an authentic original equipment manufacturer (OEM) replacement rear battery door engineered specifically for the Motorola LEX L10 Mission Critical LTE Handheld. Designed for frontline public safety officers, emergency services personnel, and enterprise security teams, this rugged rear cover protects the battery compartment against physical shock, drop impact, and moisture penetration. Sourced directly from our verified inventory of Motorola Two-Way Radios & Accessories, the HKLN4619A replaces lost, cracked, or worn factory battery doors to keep your LTE broadband device in active duty readiness.
Engineered specifically for use with the standard-capacity 2280/2340 mAh battery pack (PMNN4472A), the Motorola HKLN4619A fits flush against the LEX L10 rear chassis to maintain the device's slim, pocketable form factor. Crucially, the door features integrated elastomeric perimeter sealing that preserves the handheld's factory IEC Standards IP67 water submersion (up to 1 meter for 30 minutes) and dust-tight rating. Utilizing heavy-duty reinforced locking tabs, the door prevents accidental battery ejection during active physical pursuit or tactical operations.

Frequently Asked Questions
Which device does the Motorola HKLN4619A battery door fit?
The HKLN4619A is engineered specifically for the Motorola LEX L10 Mission Critical LTE Handheld.
Does this battery door fit the newer Motorola LEX L11?
No. The LEX L11 features an entirely redesigned, larger physical housing and battery interface. The LEX L11 requires part number HN001154A01 for standard slim batteries or HN001155A01 for high-capacity batteries.
Will this door fit high-capacity extended batteries on the LEX L10?
No. The HKLN4619A is contoured specifically for the standard slim battery (PMNN4472A). If your LEX L10 uses the thicker, high-capacity 4560 mAh battery (PMNN4475A), you must use the extended battery door, part number HKLN4620A.
Why is replacing a damaged battery door important?
A damaged, cracked, or warped battery door compromises the internal gasket seal, allowing water, humidity, and dust to reach the internal battery contacts and SIM slot. A fresh OEM door restores factory IP67 water submersion resistance.
Does this replacement door include the battery?
No. The HKLN4619A includes only the authentic Motorola replacement polymer back cover door. The battery pack is sold separately.
