Are Duracell Plus Power 9V batteries reliable for long-term use?

When it comes to batteries, reliability over time is one of the most important factors. Some products perform well initially but lose power quickly. I’m interested in whether these 9V batteries maintain consistent performance, especially in devices that require stable energy. Would like to hear real usage experiences.

When choosing 9V batteries, reliability is usually more important than anything else, especially for devices like smoke detectors or audio equipment. Many cheaper options may seem similar, but they often lose power much faster. I was checking details on https://www.comparor.com/uk/duracell-plus-power-alkaline-batteries-9v-pp3.html and it looks like this model is designed for stable long-term use. That kind of consistency can make a big difference in everyday situations.
