The Aimpoint Comp M2 is a popular red dot sight known for its reliability and durability. A crucial aspect of maintaining its functionality is understanding and managing its battery life. This guide delves into everything you need to know about the Aimpoint Comp M2 battery, from battery type and life expectancy to replacement procedures and troubleshooting tips. We'll cover everything from prolonging battery life to dealing with a dead battery in the field.
Understanding the Aimpoint Comp M2 Power Source
The Aimpoint Comp M2 utilizes a single DL1/3N battery, also known as a CR2032. This is a readily available, inexpensive, and common lithium battery type, making replacements easy to find at most sporting goods stores, online retailers, and even pharmacies.
Battery Life Expectations
The Comp M2's battery life is significantly impacted by 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 drastically extend battery life.
- Environmental Conditions: Extreme temperatures (both hot and cold) can affect battery performance and lifespan.
- Battery Age: Even unused batteries degrade over time. Using fresh batteries is always recommended.
Aimpoint officially states that the battery life can range from 2 years to 5 years. However, realistic expectations based on user experiences and brightness settings should fall in the 2-3 year range under typical use. Remember, these are estimates; your actual battery life may vary.
How to Check Your Battery
While there isn't a direct "battery level indicator" on the Comp M2, you can infer battery status by observing the red dot's intensity. A significantly dimmer or flickering red dot is a strong indicator of low battery. Aimpoint recommends replacing the battery when the dot begins to noticeably dim. Don't wait until the dot disappears completely; you'll want to replace it before you need it in a critical situation.
Replacing the Aimpoint Comp M2 Battery: A Step-by-Step Guide
Changing the battery on the Aimpoint Comp M2 is a relatively straightforward process:
-
Gather your materials: You will need a new DL1/3N (CR2032) battery.
-
Access the battery compartment: Locate the small screw on the bottom of the Comp M2. You'll need a small flathead screwdriver. Carefully remove this screw.
-
Remove the battery cover: Once the screw is removed, the battery cover should easily unscrew from the sight.
-
Replace the battery: Carefully remove the old battery and insert the new DL1/3N battery, ensuring the positive (+) side faces up.
-
Reassemble the sight: Replace the battery cover and screw it securely back onto the sight. Tighten the screw firmly but avoid over-tightening.
