The digital battery is based on the ordinary lead-acid battery, and the digital chip is installed, so that the digital battery has many functions that the ordinary battery does not have. If you use a mismatched digital battery or don't pay attention to saving, the battery will not be in you. Exhausted when taking a few photos. The following methods can save battery usage:
　　 1. Avoid frequent flashing: If you are not a professional photographer, unless you are not seeing the black night of the five fingers, the light intensity of ordinary daytime is enough for a general digital camera.
　　 2, try to avoid unnecessary zoom operation: zoom camera lens stretches and shrinks, very power-hungry. You can move more and use the “manual zoom” instead of “camera zoom” to save power.
　　 3. Don't let the display keep on: If you don't have much power, you can turn off the LCD screen and use the viewfinder to adjust the picture composition. For a digital camera, the LCD should be the most power-consuming part. Digital cameras can be used up to about 3 times longer than the original screen.
　　 4. Use less continuous shooting and video recording: Try to use the continuous shooting function and the dynamic video shooting function as much as possible, because the completion of these functions is to use the built-in cache of the body to temporarily save the captured picture, which consumes a lot of power.
　　 5, avoid frequent opening, shutdown: Many users know that the display is always lit and very power-hungry, so in order to save power, it is frequently turned on and off. In fact, the power that is wasted and shut down frequently may be more than that consumed by the high-brightness display. Especially for a camera with a large lens and a large telescopic lens, the switch is very power-hungry. Most digital cameras have an automatic shutdown option. This setting should not be set too short, otherwise it will easily lead to frequent opening and closing. Of course, frequent manual opening and shutdown should be avoided as much as possible.
　　 Anyone who uses a digital camera knows that there are certain restrictions on using alkaline batteries or nickel-cadmium-metal hydride rechargeable batteries. If digital cameras are compatible with alkaline batteries and nickel-metal hydride rechargeable batteries, the cost of using alkaline batteries will be compared. High, and the shooting time that can be maintained is not long. If the NiMH battery is used, although the shooting time is improved, it takes a long time to charge, and there is always inconvenience in charging when traveling. When a digital camera uses a dedicated battery, the price of a dedicated battery is generally expensive, and the purchase is too large. In the case of an emergency, it is difficult to replace it with another battery.
　　 The digital battery is the youngest battery in a digital camera. The digital battery has the same ability to output high voltage as other metal lithium batteries. The voltage range is between 3.0 and 4.0V, but it is safer than metal lithium. The reason is that it is adopted. In the lithium ion state, the digital battery has no flowable liquid electrolyte, but instead the polymer electrolyte is conductive. Compared with the aforementioned batteries, lithium-ion batteries have excellent discharge voltage, large capacity, wide operating temperature range, low self-discharge rate, long storage life, no memory effect and no environmental pollution. Kind of energy. For digital cameras, two other important advantages of digital batteries are: formability and lighter weight. The plasticity of the appearance makes the digital camera less compact than the battery, and can be made smaller; the lighter weight allows the digital camera to be more portable. The main disadvantage of digital batteries is that they have a short life span, and the number of charge and discharge cycles is generally around 300, and the price is higher.
