Energizer 123 Lithium Photo Battery, 12 Batteries, 1-Pack

This is a great pack! I got them to have for back up when our home alarm batteries need replacing. It is a great quantity and quality for the price. I will be buying this pack again.

Good life span

Great product

As good as regular batteries are, lithium technology / chemistry beats them. They last longer, work better in lower temperatures, and are lighter. We have high intensity flashlights and they each use a pair of 123 batteries. These deliver brighter light and last longer although because of the brightness, power drain is still strong. I have completely switched to Lithium batteries for all uses around the house and accept that the higher price is offset by longevity and low temperature performance.

I love the batteries. The device, an August door lock requires them. However, they only last roughly 3 weeks when the August lock is connected to a wifi network. While I understand that the device takes more power when Wifi is active, the manufacturer of either the batteries or lock should figure out a solution. 4 stars because I didn't want to take it all out on the Battery.

As advertised

Good batteries. Nice price!

I ordered these 123A size Lithium Energizer replacements when the batteries in my home window and door sensors started to weaken after 8 years. Based on previous experience, I expect these Energizers to last much longer than the originals. A review of batteries soon after purchase is probably not really all that meaningful, so I will check back when 8+ years have passed for a progress report. Since not all of the originals are going at the same time, I should be able to report on shelf life as well. Stay tuned.
