Review: Too costly Almost 400 per piece - You get only four pieces in total for the price paid. Description about the product is not clear!
Review: Duracell is pretty much the brand I always end up going back to. They just last longer than the cheap ones, and I don’t have to change them out as often. I’ve used them in toys, remotes, even my kid’s nightlight, and they hold up really well. They’re not the cheapest, but honestly it’s worth it because you don’t burn through batteries so fast. Nothing worse than something dying right when you need it, and these seem to save me from that. Overall, solid batteries. Reliable, no issues, just does what you need them to do.

### ⭐⭐⭐⭐⭐ Review
*by J***M on 13 December 2025*

There are moments, often unremarked, when one depends upon a quiet, uncomplaining force to keep the machinery of life from falling into silence. The Duracell Coppertop 9V Battery belongs to that class of steadfast companions. It does not boast or glitter; it simply endures. I placed it into devices that live in shadow—smoke alarms, measuring instruments, the unseen sentinels of domestic order—and there it labored on, faithful as an old sailor keeping watch through the night. What struck me most was its refusal to fail suddenly or theatrically. Its power ebbs with dignity, not treachery, allowing one time to prepare rather than be betrayed. In a world prone to cheap promises and abrupt endings, this battery provides continuity, a dependable current amid uncertainty. It is not romance, but reliability has its own severe beauty. Five stars, for the Duracell Coppertop performs its duty without complaint, and in doing so, earns a rare and lasting trust.
