The battery selection for handheld searchlights should balance capacity, weight, safety, and environmental adaptability. Regular maintenance and proper use can significantly extend battery life and ensure reliable operation of equipment during critical moments. If used in fields such as firefighting and rescue, it is recommended to prioritize industrial grade batteries and searchlight matching solutions.

Battery capacity and endurance
Capacity unit: usually marked in milliampere hours (mAh) or watt hours (Wh), with longer battery life as the value increases.
Range calculation:
Assuming a searchlight power of 10W and a battery capacity of 36Wh (such as 3.7V/10000mAh lithium battery), the theoretical range is:
36Wh ÷ 10W=3.6 hours (may be shortened in actual use due to brightness adjustment, circuit losses, etc.).

Actual range correction factors
|Influencing factors | Correction coefficient | Explanation|
|-----------------------|--------------|---------------------------------------|
|Circuit conversion efficiency | × 0.7-0.9 | LED driver circuit, boost loss (DC-DC conversion)|
|Depth of Discharge (DoD) | × 0.8-0.9 | Lithium batteries are recommended to be discharged to 20% capacity to extend their lifespan|
|Environmental temperature | × 0.6-1.0 | Low temperature (<0 ℃) significantly reduces the available capacity of the battery|
|Dimming mode | Proportional adjustment | Strong light mode (power) vs Energy saving mode (20%)|
Actual endurance formula
Actual endurance ≈ theoretical endurance × correction factor
-Example: With a theoretical duration of 3.6 hours and a comprehensive correction factor of 0.75, the actual range is approximately 2.7 hours.

Portability and Lightweight Design
Compact size and low weight: Most models weigh between 90g and 300g, with WHZH7106 weighing only 90g and WHHZ7520 weighing 160g, making it convenient to carry around or put in a pocket.
Multiple carrying modes: Supports handheld, hanging rope, strap or magnetic fixation (some models such as WHHZ7520), suitable for different work habits.
Lightweight and tough material: The shell is made of aluminum alloy and high-strength engineering plastic. For example, WHHZ7632 uses PC material, which combines impact resistance and lightweight.
