Review on Rayovac Fusion Premium Alkaline 9V Batteries, Red/Silver, 2 Count by Jorge Gutierrez

Revainrating 4 out of 5

Shelf life is almost 5 years

Received a pair of these batteries today. The expiry date listed on it was February 2024, leaving 4.5 years until expiration. Output voltage 9.7V. For the convenience of one-day delivery and at a price of $3.35 each, I am satisfied. I use it in a heat gun with an infrared thermometer. They are made in China. Also, the infrared thermometer was purchased on 11/2015 and came with a battery (non-alkaline) that expired on 8/2017. Lasted until 10/2019 with moderate use.
