The Burris FastFire II is a popular red dot sight known for its compact size, rugged construction, and ease of use. However, like all electronic devices, it relies on a battery for power. Understanding the battery type, replacement process, and maximizing battery life is crucial for maintaining optimal performance in the field. This guide provides a comprehensive overview of everything you need to know about the Burris FastFire II battery.
Understanding the Burris FastFire II Battery
The Burris FastFire II utilizes a single CR2032 3-volt lithium battery. This type of battery is readily available at most sporting goods stores, pharmacies, and online retailers. Its small size contributes to the sight's compact profile, while its lithium chemistry ensures a long lifespan and consistent voltage output, crucial for reliable red dot illumination.
Battery Life Expectations
Battery life on the FastFire II varies depending on several factors:
- Brightness Setting: The higher the brightness setting, the faster the battery will drain. Using the lowest brightness setting compatible with your lighting conditions will significantly extend battery life.
- Environmental Conditions: Extreme temperatures (both hot and cold) can impact battery performance and reduce lifespan.
- Battery Age: Even unused batteries degrade over time, so using fresh batteries is always recommended.
While Burris doesn't provide a precise runtime, users generally report battery life ranging from several months to over a year with moderate use and lower brightness settings. Regularly checking your battery level is essential, especially before heading out for important shooting sessions.
Replacing the Burris FastFire II Battery
Replacing the battery is a straightforward process, requiring no special tools:
- Remove the sight: Carefully remove the FastFire II from your firearm.
- Locate the battery compartment: The battery compartment is typically located on the bottom of the sight. You may need to gently pry open a small access door or use a small, flat-head screwdriver to release it. Consult your owner's manual for specific instructions related to your model and mounting method.
- Remove the old battery: Gently remove the depleted CR2032 battery. Note the positive (+) side of the battery for correct orientation during installation.
- Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side is facing upwards, as indicated in the battery compartment.
- Reassemble the sight: Carefully reattach the battery compartment cover or door.
- Remount the sight: Carefully remount the sight back onto your firearm.
Important Note: Always use genuine CR2032 batteries. Using counterfeit or off-brand batteries can lead to reduced performance, shorter lifespan, or even damage to the sight.
Tips for Maximizing Burris FastFire II Battery Life
Here are some practical tips to get the most out of your FastFire II battery:
- Turn the sight off when not in use: This is the single most effective way to conserve battery power.
- Use the lowest brightness setting possible: Adjust the brightness setting to the minimum level that provides sufficient illumination for your shooting conditions.
- Store the sight in a cool, dry place: Extreme temperatures can negatively affect battery life.
- Avoid leaving the sight in direct sunlight: Prolonged exposure to direct sunlight can accelerate battery drain.
- Periodically check the battery level: Regularly checking the battery level will help you avoid unexpected power failures.
By following these simple guidelines, you can significantly extend the life of your Burris FastFire II battery and ensure your red dot sight remains operational when you need it most. Remember to consult your owner's manual for specific instructions regarding battery replacement and maintenance for your particular model.
