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.

I have used the energizer lithium 9 V batteries for years in my radio, and it works for a very long time. It’s very lightweight and never gets overheated like some batteries do

I have these in all of my smoke detectors, and they are going strong! They have great power. The size and weight are similar to other 9V batteries. The packaging was easy for me to open.
