Lasted 5 years and 8 months.
I am going to assume that the energizer ultimate lithium 9V is as good as or better than the energizer advanced lithium 9V. I installed an energizer advanced lithium in a Kidde model i9040 smoke detector on February 17, 2015. Today, October 24, 2020 the smoke detector started chirping, indicating low battery. The energizer ultimate lithium batteries that I purchased in 2017 are still going strong. By the way, the 10 years indicated on the packaging are for shelf life only, not for powering smoke detectors 10 years. Long lasting!

Las compré para usarlas en una cámara Olympus Infinity Stylus. Llevo 2 meses usando la cámara y el indicador de batería me sigue mostrando que la carga aún está llena. Creo que el paquete completo me durará para más de un año.
