Duracell 2032 Battery Review: Reliable Power with Key Safety Features
My two-pack arrived on schedule in a slim, secure cardboard box. Each battery was sealed tightly in its own child-proof plastic blister pack, requiring scissors to open. The batteries themselves were pristine and ready to use right away.
Built Quality
The battery has a solid, well-constructed feel with a clean, polished metal finish. The bitter coating is a subtle but important textural addition that doesn't interfere with its function.
Long-Lasting Power & Performance
I used one of these Duracell 2032 batteries to replace the dead cell in my car's key fob. The fob immediately recognized the new battery, and the lock/unlock buttons responded from over 50 feet away across a parking lot. After two months of daily use, the signal strength remains just as strong. I also placed the second battery into an Apple AirTag I use to track my luggage. It survived a cross-country flight and a week of travel, with the Find My app showing a consistent, strong signal the entire time without any drop in reported battery life.
Child Safety Design
The non-toxic bitter coating is a genuine deterrent. Out of curiosity, I lightly touched my finger to the battery's surface and then to my tongue. The intensely bitter taste was immediate and unpleasant, lingering for a few minutes. This feature provides real peace of mind. The packaging is equally impressive; the hard plastic clamshell is fused so tightly that it’s impossible to tear open by hand without using a scissor blade to cut through the perforated edge.
Guaranteed Shelf Life
Knowing these batteries are guaranteed for a decade in storage, I bought a few extra packs. I keep them in a drawer with my other spare household electronics supplies, confident they will hold their charge until my next key fob, thermometer, or garage door remote needs a fresh cell.
Ease of Use
While the packaging is intentionally tough, a quick snip with scissors pops the battery out cleanly. It slid perfectly into the battery compartment of my key fob, making a secure connection with the metal contacts for immediate power.
