Energizer Max AAA Alkaline Battery 4 ea (Pack of 2)

Best lithium battery, but don't think they outperform for the price. Yes they hold a charge for years when not in use, so they're good in low power consumption products, but are not worth the money compared to alkaline when using in a flashlight and measuring hours of light time vs. cost of battery. Triple the price does not equate to triple the hours of use, but they'll hold a charge and do not deteriorate in voltage over long periods of time when not in use. Good for storage, emergencies, use in a flashlight that sits in a car unused for a long time. But if you're burning up batteries with high use in toys and daily use, go with Alkaline.

I use the Energizer Ultimate Lithium AA batteries throughout my Airbnb to keep essential devices — from smart locks to remotes — running smoothly. They last significantly longer than standard batteries, which means fewer replacements and more peace of mind. Guests benefit from uninterrupted convenience, and I appreciate the dependable performance. Long-lasting, low-maintenance, and a smart investment for any hosting setup.

Good quality

Work well for my cameras, and fit perfect. Of residing in the city (busy street) battery life is not the best.

All of our smoke detectors needed new batteries. These were the win. They last a year and will be replaced with like kind. Easy to install and good value

Good price better than box stores. Just installed in my Smoke Alarms

Works great for our outdoor security cameras. Batteries are long lasting. We tried other brands, but these hold up the best, and we don’t have to change batteries as often. It was a noticeable difference when we switched to using these.

Lithium batteries last so long
