The battery life of digital night vision devices varies due to many factors. Here is a detailed introduction:
Battery life of different products
Battery life of some common digital night vision devices:
1、onick NP-1600 digital night vision device: can work continuously for 10 hours without infrared, and about 3 hours after turning on the infrared light.
2、onick S60 handheld infrared thermal imager night vision device: battery life up to 8 hours.
3、NB-500 full-color night vision device: the longest battery life in day mode is 5 hours, and the longest battery life in night vision mode is 4.5 hours.
4、NB-590 handheld infrared thermal imaging night vision device: built-in 6000mAh battery, continuous working time ≥5h.
For reference of other similar products: general digital video cameras such as Songdian DV, the battery life is 60-120 About minutes. Since it is not a professional night vision device, the battery life will be shorter when the night vision function is turned on, but it can be used as a reference.
Factors affecting battery life
Device type: Different types of digital night vision devices have different energy consumption. For example, night vision devices based on thermal imaging principles usually consume more power than night vision devices based on optical and electronic magnification principles, resulting in relatively shorter battery life.
Usage environment: In extremely cold or hot environments, the performance of the battery will be affected, resulting in shorter battery life. Generally speaking, too low a temperature will slow down the chemical reaction of the battery and reduce the available power; too high a temperature may cause the battery to overheat, accelerate power consumption or even damage the battery.
Usage mode: If you use high-power consumption functions for a long time, such as continuously turning on the infrared fill light, recording or using high-power electronic zoom, the battery power consumption will increase significantly and the battery life will be shortened. On the contrary, if you only use the camera function or use the device intermittently, the battery life will be relatively long.
Battery type: Common battery types include lithium batteries, nickel-metal hydride batteries, etc. Different types of batteries have different characteristics such as energy density and self-discharge rate, which directly affect the battery life performance. Lithium batteries generally have higher energy density and lower self-discharge rate, providing longer battery life at the same volume.
