Seems to be working well
So far so good. Just installed it and it charged up and it’s working fine. Will have to wait and see how long it lasts. Got 6 years out of the original.

Questions remain
The battery arrived on time. When checking the manufacturing date on the box I learned that the battery is already 9 months old. Not happy about this as it raises questions on longevity; however, when buying the battery I also purchased the 2 year protection plan. The installation was easy. I was hoping the box would provide suggestions on how to dispose of the old battery but it did not. The battery is working but I am not in the position of weighing in on longevity or value for money although I do feel the purchase price was a bit much.

Batterie semblable à l’originale, préalablement très longue a recharger.
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.
