This battery last significantly longer than cheaper brands and keep devices powered for months without issues. They are not the cheapest, but the quality and durability worths the price since its unusual size. It’s kind of hard to find them so make sure you’re ordering the correct type.

Duracell batteries lasted for months in my TV remo
on December 4, 2025

I used Duracell batteries in my TV remote that gets used daily, and they lasted much longer than the previous brand I had. The power stayed strong with no signs of fading or weak performance. I didn’t have to replace them for months, which was a huge plus. Overall, they were reliable, long-lasting, and worth the price.

The only batteries that I use for many years. The battery life seems to last longer than other batteries. Power and packaging seems just like other brands.
