The EOTech EXPS3 is a popular holographic weapon sight known for its rugged durability and clear sight picture. However, understanding its power source is crucial for maintaining its functionality and readiness. This guide delves into the specifics of the EOTech EXPS3 battery type, offering practical advice for users.
What Type of Battery Does the EOTech EXPS3 Use?
The EOTech EXPS3 uses a single 1/3N CR123A lithium battery. This is a common battery type readily available at most sporting goods stores, online retailers, and even some pharmacies. It's important to note that using the correct battery type is critical. Using an incorrect battery can damage the sight, void the warranty, and potentially lead to malfunction during crucial moments.
Why a CR123A Battery?
The CR123A battery's high energy density makes it ideal for powering the EXPS3's demanding electronics. Its compact size allows for a sleek sight design without compromising performance. This battery type is also known for its extended shelf life and relatively stable voltage output, ensuring consistent sight operation even after prolonged storage.
Maximizing Battery Life in Your EOTech EXPS3
While the CR123A provides ample power, several practices can significantly extend the battery's lifespan and minimize downtime:
1. Battery Quality Matters
Not all CR123A batteries are created equal. Opt for high-quality batteries from reputable brands. Lower-quality batteries can have inconsistent voltage output, leading to reduced sight performance and potentially shorter lifespan.
2. Turn Off When Not in Use
This might seem obvious, but consistently turning off your EXPS3 when not actively shooting significantly reduces battery drain. The EXPS3's standby power consumption, while low, adds up over time.
3. Store Batteries Properly
Proper storage of spare batteries can dramatically increase their shelf life. Keep batteries in a cool, dry place away from direct sunlight or extreme temperatures. Avoid storing batteries in close proximity to metal objects.
4. Check Battery Level Regularly
Regularly checking the battery level, either via the sight's battery indicator (if equipped) or by testing with a multimeter, allows for proactive battery replacement before unexpected failure occurs. This is particularly important in tactical or critical situations where the sight's reliability is paramount.
5. Understand Battery Runtime
The battery runtime of the EOTech EXPS3 varies depending on usage and environmental factors. However, under normal operating conditions, you can expect a reasonable battery life. Always consult the manufacturer's documentation for the most accurate runtime estimates.
Conclusion: Ensuring Your EOTech EXPS3 Remains Operational
Understanding the battery requirements of the EOTech EXPS3 is fundamental to its reliable performance. Using the correct CR123A battery, coupled with good battery management practices, ensures the long-term usability and dependability of this crucial piece of equipment. Prioritizing battery quality and following the tips above can significantly reduce downtime and maintain the readiness of your sight.
