Battery maintenance For a (segment) digital camera battery, the length of time used is not only related to its quality and power, but also has a lot to do with the user's operation. Most photographers are habitually placed in the camera bag after each use of the camera, or placed in the cabinet, the battery is not taken out and stored separately, this seems to sound no problem, but not conducive to the battery protection.
Usually if you don't use the camera for more than 15 days, it is best to take the battery out of the camera and store it separately. The best place to store it is in a dry and cool place, and do not store the battery together with metal objects.
Rechargeable battery test According to our survey, most of the digital cameras currently available on the market use lithium batteries, which are relatively convenient to store. The only thing to note is that if you don't use it for a long time, it is best to activate the battery once every 2 months, that is, to discharge it once, which can effectively extend the battery life.
As for the Ni-MH No. 5 battery, the most annoying thing is the memory effect. This effect will reduce the total capacity and usage time of the battery, and as time goes on, the stored charge will become less and less, and the battery will be consumed more and more. The sooner. Therefore, you should try to use up all the power and recharge it. Every time you charge it, you must charge it to the fullest to power off.
If you use alkaline batteries temporarily when you go out, be sure to take them out in time. Otherwise, if you don't use them for a long time, the battery will easily splatter the circuit and the camera will not escape the fate of scrapping.
For users who use alkaline batteries, as mentioned above, it is important to remember to remove the battery after using the digital camera to avoid battery leakage and damage the machine.
For users who use rechargeable NiMH batteries and lithium batteries. The charging of the battery is very particular. The battery that you just bought is generally low or has no power. The first charge must be sufficient. The charging time of a lithium battery generally exceeds 8 hours, while the charging time of a nickel-hydrogen battery generally exceeds 16 hours. To achieve the best results, that is, to make the battery reach its maximum power, it is usually necessary to repeatedly charge and discharge more than 3 times. After the battery is used three times, it is best to find a chance to completely discharge the battery and then charge it. Try not to charge it repeatedly when the battery has residual power, otherwise it will shorten the battery life. After the battery is fully charged, it is generally hot. It is best to wait until the battery is cooled before loading it into the camera.
However, it is noted that lithium batteries do not discharge because they have no memory effect, otherwise they will only damage the battery structure and deplete the battery life.
In addition, in order to avoid the loss of power, users of nickel-metal hydride batteries should not let the positive and negative poles of the battery contact the conductor at the same time after charging the battery. For example, do not touch the two ends of the battery at the same time with your fingers. Users who use lithium batteries should try to keep the positive and negative contact points of the battery inside the camera battery box clean. If necessary, use a dry cloth to wipe gently and then insert the battery.
It should also be noted that even users who use lithium batteries should fully discharge the digital camera when it is not used for a long time, then remove the battery and store it in a dry, cool environment. Another thing to note is that users who use nickel-metal hydride batteries or lithium batteries should not put their batteries in their bags, pockets, handbags or containers filled with metal objects to prevent short circuits. .
Digital camera battery saving method:
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.
6, optical anti-shake 毋 normally open: optical anti-shake is achieved by driving the lens assembly or image Sensor to offset the relative motion between the image of the object and the sensor. No matter which kind of optical image stabilization method, it will cause a lot of power consumption. In particular, some models can set the anti-shake mode to “normally openâ€, which will cause more power loss. For this reason, we should turn off the optical image stabilization function in a scene with good lighting. When it is necessary, it should also use the "normally open" mode.
The battery is the key to digital cameras. I am afraid that the importance is second only to the lens. To be successful, a strong battery is essential for subsequent power supply. However, if the battery is in good condition, if it is not well maintained and maintained, it will take a long time to lose strong power, so the maintenance of the battery is very important.
