The packaging of the Duracell 9-volt battery is labeled very well to let you know product. Duracella's a reliable battery and I trust it for its known current and power to trust in my smoke detectors.

Tried and true Duracell batteries, work amazing every single time. Last forever and very efficient, smoke alarm batteries last me about two years with one battery.

Reliable and long lasting. Truly trusted for the most important things in my homelike smoke detectors. Easy to find in stores and online. Even though off market brands are cheaper, I trust Duracell for the important stuff
