Product Information

It is commonly associated with the LiftMaster 373P Premium remote battery layout and is used where the remote battery tray calls for CR2016 cells. This is a battery replacement item only and does not change remote frequency, coding, or receiver compatibility.
Compatibility and Application
This battery is commonly used with select LiftMaster remote controls and is especially associated with the 373P Premium remote. Compatibility is based on the battery size printed in the remote, not the garage door opener model.
Use Notes

- Does not reprogram the remote or change the opener/receiver frequency.
- The 373P remote may require more than one coin cell depending on the function being restored.

Technician Note
Do not force a thicker coin cell into a CR2016 battery tray. A wrong-size battery can bend the contacts, crack the case, or create intermittent power that looks like a remote or receiver problem.
Before Ordering
- Open the remote and confirm CR2016 is printed in the battery area.
- Check how many CR2016 cells are required for the remote version.
- Note battery polarity before removing the old battery.
- Inspect the contacts for corrosion or looseness before installing the new cell.
Professional Advisory
Remote batteries are low-voltage service items, but damaged or corroded remotes should be replaced rather than forced back into service. Keep coin batteries away from children and dispose of used cells properly.
