DURNERGY 9 Volt Battery for Smoke Alarms, 9v Battery 8 Pack, Smoke Detector Battery, 9v Batteries, Square Batteries 9V Alkaline Batteries, 10-Year Shelf Life

Good quality product

It works and it’s affordable! I’m not sure how long it will last, but for the price I paid, I can get three sets—definitely worth it! Just to clarify, I wasn’t paid for this review. I’m just excited to have found a reliable battery at such a low price!

These fit perfectly for items that require 9v, the battery life seems to be just as good and as strong as some other name branded batteries. They help me not go crazy, I cannot stand that chirp and I have like 4 smoke detectors in my house. I also noticed that the light on my scale is much brighter than before, I've never needed a new battery and the battery that it came with didn't power it up as much as this one.

Il fonctionne très bien

It seems like good batteries overall; however, the next day, one was already faulty after being added to a smoke detector, which was odd since the alarm started malfunctioning right after putting in one of these new batteries. I used several at the time while replacing some alarms, and the others are holding up fine so far. It’s a decent deal considering the number of batteries you get in the pack, though quality control could be better. I still have five remaining out of the 8-pack to use, so hopefully the rest perform well.
