Key Features & Benefits
• 3-Volt Lithium Chemistry: Delivers consistent, long-lasting power output to prevent signal degradation, ensuring your remote maintains its maximum operating range over years of daily use.
• Precision CR2016 Form Factor: Ensures a perfect, tight fit within specific remote battery trays, preventing the battery from shifting or losing electrical contact when the remote is dropped or jostled on a keychain.
• High Energy Density: Capable of powering demanding multi-function transmitters—such as the 373P with its proximity sensor and bright LED lights—without experiencing rapid voltage drops under heavy load.
• Extreme Temperature Tolerance: Maintains optimal chemical stability and reliable operation in severe environmental conditions, performing flawlessly from freezing winter mornings to hot summer afternoons inside a vehicle.
• Extended Shelf Life: Retains its charge for up to 10 years in proper storage, allowing facilities managers and professional technicians to safely stock multiple units for future deployment without fear of battery degradation.
Compatibility Guide
Following strict manufacturer logic, the Liftmaster 10A19 (CR2016) 3V Lithium Battery is engineered for specific Chamberlain Group access transmitters.
• Compatible Brands: LiftMaster, Chamberlain, and Sears Craftsman.
• Primary Application (373P): Specifically required for the LiftMaster 373P Premium Remote Control. Please note that the 373P utilizes a stacked battery design and requires two (2) CR2016 batteries to function correctly.

Frequently Asked Questions
Q1: How many batteries does the LiftMaster 373P remote actually require?
A1: The 373P Premium Remote requires two (2) CR2016 batteries. They must be stacked one on top of the other within the battery tray to provide the necessary power for its advanced proximity lighting and RF transmission features.
Q2: Can I use a CR2032 battery instead of this CR2016?
A2: No. While both batteries output 3 volts and share the same 20mm diameter, the CR2032 is 3.2mm thick, which is exactly twice the thickness of the CR2016 (1.6mm). Forcing a CR2032 into a CR2016 slot will permanently damage the remote's casing and contact pins.
Q3: How do I know when it is time to replace the battery in my remote?
A3: The most common indicators of a failing battery include a noticeably decreased operational range, the requirement of multiple button presses to activate the door, or the LED indicator light on the remote becoming dim or failing to illuminate entirely.
Q4: Which side faces up when installing the battery?
A4: In almost all LiftMaster remotes, the positive (+) side of the battery, which features the engraved text and battery size, should face upwards and make direct contact with the primary metal retaining clip.
Q5: Are there any specific handling instructions during installation?
A5: It is highly recommended to handle lithium coin cells strictly by their edges. Touching the flat top and bottom surfaces with bare fingers can transfer microscopic skin oils that increase electrical resistance, potentially reducing the operational efficiency and lifespan of the battery.
