Energizer CR2450 3V Lithium Coin Cell Battery

One of the most powerful coin cells on the market, the Energizer CR2450 3V Lithium Coin Cell has all the power you need to run your small electronics. These Lithium-based coin cells are built to the highest Energizer standards, featuring an incredible 620 mAh capacity that allows them to last substantially longer than their silver oxide counterparts. Their extensive 6-8 year shelf-life makes them ideal for numerous compact devices such as remote car starters, key-less entry systems, watches, and back-up power sources to keep clocks and calendars running. The CR2450s require extremely infrequent changing yet power devices you depend on every day, saving you a good chunk of cash in the long run.

Im using 5 of these for my 1980s ROSTOV CYCLOPS NS3 Night Vision Scopes IR light (laser). Kudos to Energizer for still making these dinosaurs cause I would of been out of luck using Duracells 5420s. Hahahaha see what I did there.

Awesome batteries for Viking 3350 welding hood !!!
January 11, 2018
We purchase and use these for a Lincoln Electric welding hood model 3350 and they work great and the price from Battery Junction just can't be beat. I buy several at a time to save on shipping and it still costs less than buying locally. Thanks Battery Junction.

Great deal but slow shipping

Great pricing but took over 2 weeks to get. Since they are batteries and the holidays I am assuming that is why it took so long. Will order again
