These Energizer CR2 lithium batteries do exactly what they’re supposed to—reliable power with zero hassle. I’m using them in my Vortex rangefinder, and performance has been solid. Fast readings, no lag, and consistent output even in colder temps. They hold their charge well, and Energizer’s lithium cells tend to last noticeably longer than cheaper off-brands, so you’re not constantly swapping batteries during a hunt. Packaging is clean, batteries are fresh, and the price is reasonable for the quality. If you need dependable CR2s for optics or other gear, these are a safe bet. Read more

I have 2 transmitters for my Shearwater Perdix dive computers and these are the exact batteries needed. I change batteries at the beginning of the dive season (June) and have never needed to replace a battery mid-season. I only do about 30-40 dives/year, so my schedule does not really tax the endurance of the battery but they work well. Read more
