Digital camera battery maintenance and maintenance knowledge
Digital cameras rely primarily on batteries to provide power, but if you're using a mismatched battery or don't pay attention to saving, the battery will run out when you're not taking a few photos. Of course, the battery will eventually run out, and when you find that they are running out, you need to replace them.
There are also many places to pay attention to the storage and carrying of batteries. The rechargeable battery that you just bought is generally low or has no power and should be charged before use. The fully charged battery is very hot and should be cooled before being loaded into the camera. In order to prolong the shooting time, you should try not to use the LCD viewfinder during shooting; reduce the number of optical zooms; reduce the number of times the flash is used; pay attention to the integrity of the battery insulation, and if it is found to be damaged, it should be adhered with a transparent tape.
Regardless of the type of battery, as long as it is sold with DC, there are general precautions in the manual, and some manufacturers even print a separate guide on the use of batteries and chargers. These instructions are some of the most basic but also necessary maintenance methods, such as the battery should choose the charging method, charging time and so on. It is a pity that many users often ignore these instructions and put them on the shelf. Recommendation: For DC novices, it is absolutely necessary to spend a little time reading these guides.
We should try to save battery usage when using it. The first is to avoid unnecessary zoom operation. If you want to zoom, it is recommended to move the camera to get the same zoom effect! Secondly, avoid frequent use of flash, flash is a big power consumer, it is recommended that you do not use it if you have to. . It is better to use the viewfinder instead of the LCD display when adjusting the image. The LCD display consumes a lot of energy, so it's best to use it less, because normal shooting can be done through the viewfinder. Of course, you can't block it to save power. For example, the LCD screen is an indispensable part when shooting at close range. Finally, remember to turn it off when not using a digital camera.
There are two types of batteries used in today's DCs: dedicated lithium batteries and AA batteries (the most commonly used nickel-metal hydride rechargeable batteries). The special lithium battery is light in weight, large in capacity, environmentally friendly, and has almost no "memory effect", but it is expensive, has poor versatility, and has a lot of fakes. Nickel-metal hydride batteries have the advantages of high capacitance, large depth of discharge, overcharge and overdischarge, and short charging time. The most important thing is that nickel-metal hydride batteries are cheap and versatile.
The power consumption problem of digital cameras is a big problem. Even with enough batteries, it will cause a lot of trouble because of the frequent replacement of the battery, not to mention the problem that there is not enough battery to make the digital camera unusable. Therefore, we must pay attention to the correct use and maintenance during charging and use.
When you purchase a new battery or a battery that has not been used for several months, you can fully activate the electronics after a few full cycles, otherwise the battery life will be shorter in the future. Lithium batteries must be charged for more than 6 hours, and nickel-metal hydride batteries must be more than 14 hours, so that the battery can be fully charged.
Using the original charger and battery will help extend battery life. For charging time, it depends on the charger and battery used, and whether the voltage used is stable.
When the battery still has residual power, try not to recharge it to ensure battery life. Even if the battery has been used up on the digital camera, in fact, there is still a little power left in the battery. If the rechargeable battery is repeatedly charged without running out, the battery life will be slowly shortened. In order to restore the original time to the original level, it is necessary to repeatedly "recharge after use". At this time we can use a small flashlight to solve this problem. If it is a rechargeable battery No. 5, it can be charged in the flashlight and then recharged.
Turn off the LCD display, a large power consumer, and use the optical viewfinder. If you have to use the LCD display, it is best to reduce its brightness or switch to black and white mode. This saves power and extends battery life.
The battery is fully discharged and recharged periodically. The easiest way is to use an adjustment charger or a pulse charger.
Do not use old and new batteries at the same time. Even with the old and new batteries of the same brand, it will cause damage to itself, and the circuit parts related to digital cameras will be dangerous. Therefore, you must pay attention to the use of new and old batteries.
Usually, many charging problems are caused by the battery's contact points being unclean, so you should use a cotton swab dipped in alcohol to wipe the contact points of the cleaning battery.
Pay attention to the temperature of charging and use, which is especially important for NiMH batteries. Battery charging should be performed at an ambient temperature of 0 °C to 40 °C. Charging below 0 °C will cause the internal charge of the battery to be abnormal, resulting in an unrecoverable performance that continues to decrease. Charging above 40 °C may cause leakage.
If you are not using the camera for a long time, remove the battery from the camera and store it in a cool, dry place.
No matter which kind of rechargeable battery is used, it should not be put into the digital camera immediately after charging. It is better to leave the battery that has just been charged for a while. This is mainly because the voltage of the closed circuit of the battery that has just been charged has It may be higher than the rated voltage. If the camera is loaded immediately, it will affect the relevant circuit components inside the camera. Therefore, it is best to wait until the rechargeable battery is self-discharged to the rated voltage. Of course, don't leave the fully charged rechargeable battery unused for a long time, which is not good for the rechargeable battery itself.
Finally, I would like to remind you that if you can use the AC voltage regulator to adapt the power supply, it is best to use the AC voltage regulator to adapt the power supply. After all, the cost of the rechargeable battery is still high. Most digital cameras are equipped with their own AC regulated power supply. Before using it, please make sure that your AC adapter power supply is external 110V or 220V, because if the plug is not properly installed, it is easy to burn the power supply or even the camera. Don't use other voltage-regulated power supplies at will, because the cameras produced by various camera manufacturers have different adaptation voltages, currents, and specifications. It is easy to use improperly regulated power supply. Damage to the camera's power connector. In severe cases, the camera may be burnt out due to voltage and current mismatch. Therefore, we must pay special attention to it.
Most people don't pay much attention to the cleaning of batteries. To avoid the problem of power loss, keep the contact points on both ends of the battery and the inside of the battery cover clean. If necessary, gently wipe with a soft, clean, dry cloth. Never use a cleansing or chemically soluble detergent such as thinner or a solvent containing alcohol to clean your digital camera, battery, or charger. In addition, before using the battery, use a soft dry cloth to clean the contact points on both ends of the battery, and keep the contact points at both ends of the battery as clean as possible to ensure that the battery is fully charged. If the electrode of the battery is oxidized, wipe it off. If it is severely oxidized or peeled off, replace it with a new one.
Charging with the correct method has a great impact on the battery. Using the original charger and battery will help to extend the battery life. For charging time, it depends on the charger and battery used, and whether the voltage used is stable. If it is the first battery used (or a battery that has not been used for several months), remember that the lithium battery must be charged for more than 6 hours, and the NiMH battery must be more than 14 hours, otherwise the battery life will be Will be shorter. It is generally necessary to go through several charging/discharging processes to achieve optimum efficiency. When the battery still has residual power, try not to recharge it to ensure battery life. If you charge a nickel-cadmium battery, stop charging it for a while, then charge it again. This will not fill the battery. This is what we call the “memory effectâ€, which reduces the total capacity and usage time of the battery. As time goes on, the stored charge will be less and less, and the battery will be used faster and faster.
In addition, if you do not intend to use the digital camera for a long time, you must remove the battery from the digital camera or the charger, and discharge it completely, then store it in a dry, cool environment, and do not use the battery and the general Metal items are stored together. Because the battery is stored in a digital camera or charger for a long time, it may cause leakage and damage. In order to avoid a short circuit in the battery, when the battery is not in use, it should be stored with a protective cover. Be especially careful when storing fully charged batteries, no matter which type of battery is the same, never in a bag, pocket, tote bag or other container containing metal objects.
