I trust Energizer's Ultimate Lithium 9V Batteries and use them in our smoke detectors, son's toys and appliances around our home. They are reliable, affordable, and last a long time.

These Energizer batteries really do keep on going and going. I have these in many different electronics around my home and I really don't need to replace them very often, they don't seem to drain very quickly.

This is my go to battery for my smoke alarms in my home. I have 4 alarms in my home and even if I miss my mid-year change out they are still charged and protecting my home.
