First off, these batteries are legit. I’ve been using them for my dog’s fence collar after ditching those overpriced 'Power Caps.' With a hobby knife and some patience, I popped these in as replacements—same voltage, same performance, way cheaper. Pro tip: A dab of super glue keeps the cover snug if you’re DIY-ing like me.
They arrived fully charged and fit perfectly in my Garmin power pedals too. At first, I was skeptical about the DL1/3N vs. CR1/3 labeling, but they’re identical. No hiccups there—just smooth, reliable power for my rides.
But here’s the catch: Don’t expect miracles in high-drain devices. In my laser sight, they burned out way faster than I hoped, even sitting unused for months. Not ideal for emergency gear where reliability is non-negotiable.
Price-wise? Decent for Duracell quality, but still stings a bit when you need frequent replacements. Solid for niche uses (like hacking Power Caps), but maybe stock up if your gadget guzzles juice.
