LiftMaster K41-0105-000 33Ah Battery Tray — Heavy-Duty Gate Operators
LiftMaster K41-0105-000 33Ah Battery Tray — Heavy-Duty Gate Operators
The LiftMaster K41-0105-000 is the 33Ah battery-tray service reference identified for documented heavy-duty gate-operator installations. It provides the specified physical battery support rather than supplying batteries, a charging circuit or a complete larger-battery conversion. Match the exact enclosure, mounting position and approved battery arrangement before ordering. The33Ah designation describes the intended battery-capacity context, not a promise of a particular backup runtime or permission to install any battery that can be placed inside the cabinet.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| HD arrangements specifying K41-0105-000 | Match enclosure and tray attachment. |
| 33Ah battery layout | Confirm approved battery dimensions, quantity and connections. |
| INBATT33 industrial support | Separate service reference and application. |
| Other33Ah trays | No interchangeability from capacity wording alone. |
| Battery-capacity changes | Require the complete approved conversion and charging requirements. |
Evaluate the Entire Battery Installation Before Increasing Capacity
Record the operator and enclosure model, existing battery dimensions and the intended battery arrangement. A larger battery can require different mounting and wiring, and the charger or solar system must support the approved configuration. Do not assume that installing a larger tray authorizes any battery chemistry, voltage or capacity that physically fits.
Have the installer inspect the original support, retention and cable routing. Batteries are heavy and their terminals can deliver substantial fault current even when mains power is disconnected. Preserve the manufacturer’s mounting clearances and avoid routing cables across sharp edges or moving components. Diagnose weak backup performance before assuming a capacity change is the necessary repair.

Package Contents and Separate Requirements
This offer identifies the K41-0105-000 battery tray. Batteries, hold-downs, a complete mounting-hardware set, charging electronics and a 33Ah adapter harness are not promised as included. Confirm the current package and the operator’s complete battery arrangement before ordering. A tray-only purchase does not establish a larger-capacity backup conversion, and a diagram showing batteries above the tray does not make those batteries part of this service offer.
Safety Warnings — Read Before Installation or Service
- WARNING: Batteries can cause burns, short circuits and lifting injuries. Installation requires personnel familiar with the operator and battery safety procedure.
- Isolate mains, solar and battery supplies as directed before working on the tray or wiring. Keep tools and conductive objects away from exposed terminals.
- Support batteries during removal and installation, preserve polarity and use the specified cable routing and retention. Do not fit damaged or leaking batteries.
- After installation, verify the charging and backup functions and complete the operator’s required travel, reversal and protection checks.
Related Products and Important Differences
- LMRRUL monitored photo eye — a separate protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
- LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.
