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

Got this for my instant camera battery replacement needs, and it worked great. Energizer is always trustworthy, & appealed with the pricing of these for a pack of 2. I would recommend these. 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

Works great for replacing the battery in Google/Nest temperature sensors. They last awhile and resolved the issue I was having where the sensor would randomly disconnect from the thermostat, even though the nest app said the battery was ‘OK’. Read more
