The digital camera rechargeable battery that I 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. Try to save battery usage when using a digital camera. The first is to avoid using unnecessary zoom operations. If you really want to zoom, it is recommended to move the camera to get the same zoom effect. The second is to avoid frequent use of the flash, the flash is a large power consumer, if you have to force it, it is best not to use. 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. When the digital camera battery is used for a while, the battery must be cleaned as necessary. Many people may only pay attention to the cleaning of the digital camera lens and the body, but never thought about cleaning the battery. In order to avoid the problem of power loss, it is necessary to keep the contact points at 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 detergent such as cleansing or chemical. Pay attention to charging with the correct method during the charging process of the digital camera battery. It is best to use the original digital camera charger, which will help extend 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 charging time of the lithium battery must exceed 6 hours, and the nickel-hydrogen battery must exceed 14 hours, otherwise the battery life will change in the future. short. If the digital camera 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. If you do this, you can't charge the battery. This is what people often call "memory effects", which reduce 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. If you do not intend to use the digital camera for a long time, you must remove the digital camera 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 general metal objects. Stored together. Because the battery is stored in a digital camera or charger for a long time, it may leak electricity and cause damage.
