Avoid “rechargeable CR123A” unless explicitly stated as compatible by Vortex, as standard rechargeable lithium-ion batteries (often labeled RCR123A) may have different voltage outputs that could potentially damage your optic or perform inconsistently. The Vortex Strikefire 2 is designed for the standard 3V disposable CR123A.
How to Change the Battery in Your Vortex Strikefire 2: A Step-by-Step Guide
Replacing the battery in your Vortex Strikefire 2 is a straightforward process. Follow these simple steps to get your optic powered up again safely and correctly.
Gathering Your Supplies
Before you start, make sure you have everything you need:
- New CR123A Lithium Battery: Ensure it’s a fresh, reputable brand.
- The Vortex Strikefire 2 Optic: With the old battery needing replacement.
- A Soft Cloth: To keep dust and fingerprints off the lens and battery compartment.
- Optional: A Small Coin (like a quarter): Some models have a battery cap that can be opened with a coin. Check your specific Strikefire 2 manual if unsure.
Step-by-Step Battery Replacement
Here’s how to swap out the battery:
- Power Down: Turn off your Vortex Strikefire 2 using its power button. This is an important safety step to prevent accidental firing if the optic is mounted on a firearm. If it is mounted, ensure the firearm is unloaded and the safety is engaged.
- Locate the Battery Compartment: The battery compartment on the Strikefire 2 is typically found on the side of the optic. Look for a small, cylindrical cap.
- Open the Battery Compartment:
- On many Strikefire 2 models, the cap might have a small slot or a textured grip that you can unscrew by hand.
- If it’s a bit stubborn or has a slot, a coin can be used to gently turn it counter-clockwise. Be careful not to force it or scratch the finish of your optic.
- Remove the Old Battery: Once the cap is off, the old battery will be visible. Gently tip the optic or use a non-metallic tool (like a wooden toothpick) to carefully prise it out. Avoid using metal objects that could short-circuit the battery.
- Inspect the Compartment: Take a moment to look inside the battery compartment. Make sure there’s no dust, debris, or corrosion. If you see any, gently clean it with a dry, soft cloth or a cotton swab.
- Insert the New Battery: This is critical: pay attention to the polarity. The CR123A battery has a positive (+) end and a negative (-) end. Most optics have a diagram inside the compartment showing which way the battery should face. Typically, the positive (+) end (the flat end with the small bump) goes in first, towards the front of the optic, and the negative (-) end (the rounded end with the larger contact) faces towards the rear cap.
- Close the Battery Compartment: Carefully screw the battery cap back on. If you used a coin, snug it up by hand. Ensure it’s properly sealed to protect the battery from moisture and dust. Do not overtighten.
- Power On and Test: Turn your Vortex Strikefire 2 back on and check the brightness of the red dot. Test the different brightness settings to ensure everything is working correctly.
If your optic doesn’t power on, double-check that the battery is inserted correctly with the right polarity and that the cap is securely closed.
Maximizing Battery Life for Your Strikefire 2
Getting the most out of your CR123A battery means smarter use and proper storage. Here are some practical tips:
Smart Usage Tips
- Adjust Brightness Appropriately: The Strikefire 2 has multiple brightness settings. Use the lowest setting that allows you to clearly see the reticle in your current lighting conditions. Higher brightness uses more power.
- Turn Off When Not in Use: This sounds obvious, but it’s easy to forget. Make it a habit to power down your optic when you’re done shooting or when it’s stored.
- Avoid Extreme Temperatures: While lithium batteries are tough, prolonged exposure to extreme heat or cold can affect their performance and lifespan. Store your optic in moderate conditions when possible.
Battery Storage and Handling
Proper storage can ensure your spare batteries are ready when you need them:
- Keep Them in Original Packaging: This protects them from scratches and prevents accidental short-circuiting if they touch other metal objects.
- Store in a Cool, Dry Place: Avoid damp areas or places with rapid temperature changes.
- Don’t Mix Old and New Batteries: Always replace all batteries at once if you were using multiple. For the Strikefire 2, which uses a single battery, this isn’t an issue but is good practice for other devices.
- Check Expiration Dates: For spare batteries, periodically check their expiration dates.
For more on battery care and safety, you can refer to guidelines from organizations like the Energizer battery safety page, which offers general best practices for handling and using various battery types.
