    On my way out of the store I’m found a rack of batteries and remembered I needed a few 9V. Product placement was key and helped me a lot as the rest of the batteries are in the back of the store.

    I buy the 9v max battery energizer every year for my smoke detector. I prefer putting a new 9v battery when the time changes. It’s easier for me to remember when it’s been changed.

    Check your batteries and make sure they're not close to the "best by" date. These batteries have a 5 year shelf life, but the pack I received on Oct. 2024 have a "best by" date of Dec. 2025. It's not an expiration date, I know. The batteries still work and I kept my order. I would have just liked to receive a pack that was a little newer.
