Is There a Difference in Battery Life Among Popular Red Dot Brands?

April 5, 2026

Quick Answer

Battery life can vary significantly among popular red dot brands, with some lasting up to 50,000 hours and others only 1,000 hours. These differences are primarily due to the type and quality of the battery and the electronics used. Hunters should consider their needs and budget when choosing a red dot sight.

Battery Life Comparison

When comparing popular red dot brands, hunters should consider the battery life of each model. For example, the Aimpoint Pro lasts around 30,000 hours on a single AA battery, while the Trijicon RMR is powered by a single CR2032 battery and lasts up to 3 years under normal use. The Leupold DeltaPoint Pro also uses a single CR1632 battery and lasts around 2,000 hours, but has a more affordable price point.

Red Dot Sighting Techniques

To get the most out of your red dot sight, hunters should focus on proper sighting techniques. This includes aligning the dot with the target and ensuring a consistent shooting position. Hunters should also consider using a red dot sight with a 2 MOA dot for deer hunting, as this provides a more precise aiming point and allows for quick target acquisition.

Additional Considerations

When choosing a red dot sight for deer hunting, hunters should also consider additional factors such as durability, water resistance, and size. For example, the Aimpoint Micro T-2 is a compact and rugged sight that is designed for extreme use and can withstand rough handling. Hunters should also consider the weight and balance of the sight, as well as its adjustability and zero reset features.
