Replacement Extended-Capacity Battery Door Cover for Motorola LEX L10
Genuine Motorola Solutions Original extended-depth rear battery compartment cover engineered for high-capacity batteries on the LEX L10 LTE handheld.
The Motorola HKLN4620A (also cataloged as HKLN4620) 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 personnel, law enforcement, private security details, and enterprise operations running extended multi-shift duty cycles, this specialized cover accommodates thicker high-capacity battery packs. Sourced directly from our verified inventory of Motorola Two-Way Radios & Accessories, the HKLN4620A replaces lost, cracked, or worn extended battery doors to keep your broadband communication device fully operational in the field.
Molded with an expanded depth profile measuring 4.25 x 2.75 x 0.38 inches, the Motorola HKLN4620A provides the internal clearance required to enclose high-capacity extended batteries (such as the 4500–4560 mAh PMNN4475 series) that cannot fit beneath a standard flat door. The interior perimeter features an integrated elastomeric sealing gasket engineered to maintain factory ingress protection certified under IEC Standards (IEC 60529 IP67), shielding internal contacts, SIM cards, and microSD bays against water immersion up to 1 meter for 30 minutes. Constructed from shatter-resistant polycarbonate with reinforced mechanical snap-retention tabs, the door prevents accidental battery ejection during active physical movement or high-vibration vehicle transit.

Important Model & Battery Notes:
- This door is engineered specifically for the LEX L10 running high-capacity batteries. The subsequent LEX L11 uses a different chassis architecture and requires door part numbers HN001154A01 or HN001155A01.
- This door is contoured with deep clearance for extended high-capacity batteries (PMNN4475 series). For standard slim-profile batteries (PMNN4472A series), use the standard battery door (HKLN4619A).

Frequently Asked Questions
What is the difference between the HKLN4620A and HKLN4619A battery doors?
The HKLN4620A is an extended-depth door designed to fit thicker high-capacity batteries (such as 4500–4560 mAh packs). The HKLN4619A is the standard flat door designed exclusively for slim standard-capacity batteries (2280–2340 mAh packs).
Does this extended battery door fit the Motorola LEX L11?
No. The LEX L11 utilizes a completely redesigned physical housing and battery bay. The LEX L11 uses part number HN001155A01 for its high-capacity battery door.
Can I use this door with a standard-capacity battery?
While the locking tabs match the chassis, this door is built with added depth to accommodate thick batteries. Using it over a slim standard battery leaves internal clearance that may allow the battery to rattle or shift, and could compromise gasket compression. Use the HKLN4619A standard door for slim batteries.
Why is replacing a damaged battery cover important?
A cracked, warped, or loose battery door compromises the perimeter rubber gasket seal, exposing electrical contact pins and sensitive internal SIM slots to rain, sweat, and dirt. Replacing a damaged cover restores factory IP67 water immersion and dust protection.
Does this part include a battery?
No. The HKLN4620A includes only the authentic Motorola replacement extended polymer door cover.
