The optimal power source for the Holosun EPS Carry is typically a CR1620 3V lithium battery. This cell format provides the necessary voltage and current to operate the optic reliably. For example, a high-quality CR1620 battery ensures consistent performance and extends the operational lifespan of the optic before replacement is needed.
Selecting a suitable power source is crucial for maintaining the optic’s zero and ensuring consistent target acquisition. The lifespan of the battery directly impacts the user’s confidence in the optic’s readiness for immediate use. Historically, lithium batteries have become the standard due to their high energy density, long shelf life, and ability to function in a wide range of temperatures.
