Rayovac
The Rayovac KECR20321 CR2032 3V lithium coin cell battery is a compact power source built for the gear that matters in the field. Whether you're powering an optic's illuminated reticle, a rangefinder, a red dot sight, or any number of tactical and outdoor electronics, this 3-volt battery delivers the stable, dependable performance hunters and shooters expect when it counts. Rayovac's reputation for reliability makes this a solid choice for keeping backup batteries in your range bag, truck, or pack.
The CR2032 form factor is industry-standard for precision optics and electronics, meaning compatibility is rarely an issue. With a 225mAh capacity, this cell provides sustained power for extended use in devices engineered around this chemistry. Lithium coin cells hold their charge well in storage and perform consistently across temperature ranges, a real advantage if you're shooting from a heated truck bed in winter or glassing from a sun-baked ridge in summer.
Keep a spare CR2032 on hand—dead batteries have a way of showing up at the worst moment. A few of these tucked into your gear bag weigh nothing and can save a hunt or range session.
| Voltage | 3.0V |
| Chemistry | Lithium |
| Capacity | 225mAh |
| Form Factor | CR2032 Coin Cell |
| Brand | Rayovac |
CR2032 coin cells power many optics with illuminated reticles, laser rangefinders, thermal scopes, red dot sights, and various electronic outdoor gear. Check your device's manual or battery compartment to confirm compatibility.
Runtime depends entirely on the device and how often it's used. A light-use optic might run for months or longer on a single cell; heavier-use electronics will deplete it faster. Lithium chemistry provides good shelf life, so keep spares on hand.
Lithium batteries perform well across a wide temperature range, making them suitable for cold mornings and hot afternoons in the field. Extreme cold will temporarily reduce output, but performance typically rebounds as the battery warms.
