Is your battery backed up garage door motor beeping every 30 seconds or so? Then its probably because the old battery can no longer hold a charge. This battery did the trick for mine, a chamberlain myq opener.

Exact replacement for the Liftmaster. Silenced the annoying alarm after loss of power for a few days. System is working well with the new backup battery and alarm is silent. I would recommend this for replacement if required.

La batterie que j’ai reçu est étiquetée comme ayant été fabriquée en 2017, elle a été très longue à recharger par mon ouvre-porte (environ 72 heures), néanmoins elle fonctionne bien. On verra a l’usage combien de temps elle durera. J’ai conservée l’original pendant 7 ans.
