Energizer Ultimate Lithium 9V Batteries, 2 Pack For Multipurpose - 9V - 9 V DC - Lithium (Li) - 2 / Pack

Product arrived in perfect condition. My only problem was that a signature was required upon delivery.

I use these in my smoke detectors. They last much longer than a regular battery. It give a good feeling.

Quick delivery and the best quality batteries. I never use any other batteries.

Always have a supply. Doesn't let me down.

longest lasting on the market

lithium is the only way to go!

I am sure these are awesome batteries but they don't fit in a chamberlain garage door opener keypad and that's why I bought them. The corners of the battery are not rounded like a normal 9 volt battery and this causes the problem with fitting the intended application. I will find a use for them. I'm sure they are great batteries just like the AA and AAA are.

I purchased this 2-pack 9V Energizer Ultimate Lithium on 06/05/2025 which was delivered on 06/09/2025 as a backup batteries for my Smoke Alarm. The package looked very old and beat up. I tried to have it replaced at the Store (ST %23 04568) on 06/17/2025 but the store didn't have a 2-pack package so I ended up keeping this. According to the Customer Service Representative, I can return this but she can't give me what they have at the same price because they are not the same.

Package received OPENED!! How do I know if the batteries will work and if they have been used??? The package was intact so the batteries were aleady opened BEFORE THE ITEM WAS SHIPPED.
