Do battery types affect thermal scope performance?

Choosing the Right Battery for Thermal Scopes

Choosing the right battery for your thermal scope is crucial for optimal performance. When hunting hogs, a thermal scope’s ability to detect heat signatures is often the difference between a clean shot and a missed opportunity. Most thermal scopes use lithium-ion batteries, but the chemistry and size of these batteries can vary greatly. For example, the Anker 26800mAh PowerCore Fusion offers a high capacity at a relatively small size, making it an excellent choice for thermal scopes. However, even with a high-capacity battery, the scope’s performance can still be affected by the battery’s internal resistance and the scope’s power requirements.

Power Delivery and Thermal Scope Performance

The internal resistance of the battery affects its ability to deliver power to the scope. A battery with high internal resistance can lead to voltage sag, which can decrease the scope’s performance and heat signature detection capabilities. For example, a 12V battery with 10% internal resistance may only deliver 10V to the scope under load, reducing its performance by 17% (1V/12V x 100%). To minimize voltage sag, choose a battery with low internal resistance (less than 10%) and check the scope’s power requirements to ensure the battery can deliver the necessary power.

Battery Type and Scope Compatibility

When selecting a battery for your thermal scope, ensure it is compatible with the scope’s voltage and power requirements. Many thermal scopes use 12V or 15V batteries, but some may require a specific battery type, such as a 18650 lithium-ion battery. Check the scope’s manual or manufacturer’s website for recommended battery types and capacities. In addition to compatibility, consider the battery’s size, weight, and ruggedness to ensure it can withstand the rigors of hunting in the field.
