Μπαταρία Λιθίου Duracell 790102 3V LM 2032 2PCS

It's a battery. In a sealed packet. Just what you need.

Duracell are the best because they last the longest.

Very good product for the price I paid, considerably cheaper at City Plumbing compared to other retailers.

Great year. I don't know how the world will be in 2032, but it seems like Energizer thinks it's gonna be a great year for batteries. Small and easy to hide, they give you the extra kick you are looking for.
