Duracell 21/23 12V Alkaline Battery, 4 Count Pack, 21/23 12 Volt Alkaline Battery, Long-Lasting for Key Fobs, Car Alarms, GPS Trackers, and More

Package says Best before MAR 2023. No way to tell expiration date when ordering. Worked in my device without issue.

Received on time and was as expected.

This came right ontime to my rescue...

It’s a battery and it works fine.

Bought this for when I needed them. Purchased Nov. 2020 and tried to use them today June 2021. All the batteries in the pack were dead. Went out and purchased one at my local store, worked fine.

Definitely worth buying.

Quality product and speedy delivery.

These batteries were purchased to power my autonomous servant robot. Let me tell you, they were so powerful that it has developed new functionality. It was programmed to clean up around the house and bring me the occasional adult beverage. Now it has started calling itself Ultron and talking about world domination. It has some theory about a “sky net”... it’s so silly sometimes. Anyway.. great batteries!

Used it for my garage door opener remote.

Shipping was super fast and the battery expires in 2020 Very happy with the purchase!
