PanasonicCR123A Lithium 3V Photo Lithium Batteries, 0.67" Dia x 1.36" H (17.0 mm x 34.5 mm), Black, Gold, Blue (Pack of 4)

Works for ADT smoke alarms

Glad I found these on Amazon! Needed to replace batteries in the smoke/carbon monoxide alarms throughout my whole house. Happy these came in 4 pack!These are great value! Batteries work perfect and stopped annoying beep from alarms.The alarms were a pain in the butt to remove back but replacing was easy.Hopefully these are durable and last a long time, last ones lasted 4 years!

Not much to say, I wanted original named brand batteries to replace what came with my ADT sensors. I bought the 4 pack. First sensor (Motion Sensor) that needed a new battery after installed in 2019.. Not bad after 5 years of constant movement triggering on that one sensor in livingroom weather system in armed or not. Bedroom sensor went bad last year, so ADT sent me a new one with a new battery, so i don't have to worry about that one for a while. Will see how long our 3rd motion sensor last from first install. The rest are on windows that don'tget opeded except one sliding door. It's a battery, not rocket science. Quick tip on pulse systems to reset sensor after new battery installed, wait 2min, then walk passed sensor to get red light to glow on sensor, wait 2min again away from sensor, then put in pass code and hit off Twice. Done

Great product 👌

The real deal and fresh, too, expiration date 9.5 years from purchase.

Used in water detectors

Product arrived in less than 24 hours! Batteries for my smoke detector! I’m definitely not about to sit up & listen to chirping all day from a low battery sensor! Thank you Amazon for your speedy service
