Alright, so I finally got my hands on these Duracell Coppertop C batteries, and let me tell you—they don’t disappoint. First off, the packaging is solid (no pun intended), and you can tell these aren’t some flimsy off-brand batteries.

I popped them into my baby’s Einstein soother toy, which usually drains batteries like crazy. Three weeks later? Still going strong. That’s insane compared to the generic ones I used before that barely lasted a week.

Also, shoutout to Amazon for the lightning-fast delivery. I ordered these in a panic when our flashlight died during a storm, and they arrived the next day. Lifesaver.

Yes, they’re pricier than some other brands, but you get what you pay for. Duracell has never let me down—whether it’s toys, medical devices, or even my Roomba (which chews through batteries like candy). These last way longer.

Pro tip: Stock up during sales. Trust me, having a pack of these stashed away is like having emergency gold. 12-year storage guarantee? Sold.

TL;DR: Expensive but worth every penny. Long-lasting, reliable, and Amazon delivers them faster than pizza. 10/10 would recommend.
