Energizer Ultimate Lithium 9V Batteries (1 Pack), Lithium 9 Volt Batteries

Bought these as a replacement for security system. I like the battery life of Energizer. Also price was not bad for 6 batteries.

I purchase these lithium batteries when I need long-term performance without having to pay constant attention to whether or not the battery still has power. I find them perfect for the alarm clock backup feature in the event of a power failure and for emergency equipment like radios and flashlights that are not used every day. Their best features are their long life and dependability. These batteries outperform your typical battery by a mile. "Oh, but the cost is prohibitive," some people will say. I can attest that they are worth every penny. One would replace standard batteries at least twice before having to repurchase one of these powerhouses once.

I use them for my pistol light, typical small size battery, works great, light weight, provides a the full lighting capability of my light for full brightness, battery life honestly unknown because I am not heavily using my light.

These batteries last a long time and are essential to keeping our home safe. The main purpose of the batteries are for the smoke/carbon monoxide detector.

Good batteries for my flashlights. They usually last about 6 to 9 months .

work fine

Good quality. Ease of use. Capacity is good. Compatibility is there.I use this battery for my smoke detector. Battery quality and longevity are great.

I haven't had any trouble with these batteries. They work as intended.
