How to Choose Digital camera Battery
The power usage time is the number of photos that the digital camera can take with the original battery. Digital cameras can usually use dry batteries, alkaline zinc-manganese batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, and lithium-ion batteries as their power sources. Using a battery as a power source not only is easy to replace, but also makes the camera easy to carry, flexible to operate, and the range of battery options is relatively large.
The rechargeable battery that has just been bought is generally low or no power, and should be charged before use. Regarding the charging time, it depends on the charger and battery used, and whether the voltage is stable or not. If it is the first use of the battery, the charging time of the lithium-ion battery must be more than 6 hours, and the nickel-hydrogen battery must be more than 14 hours, otherwise the battery life will be shorter in the future. Generally, it takes several charging/discharging processes to achieve the best efficiency. And when the battery has residual power, try not to recharge it to ensure battery life. The fully charged battery is very hot and should be cooled down before loading it into the camera.
Digital cameras have a strong power consumption capacity. If you use a battery that does not match or do not pay attention to saving, the battery will run out when you have not taken a few photos. The following methods can save battery consumption: First, try to prevent unnecessary zoom operations; second, prevent frequent flash use, which is a big power user, so everyone should try to avoid using it; third, it is best to use viewfinder when adjusting the picture composition Instead of using LCD. Because most digital cameras consume more power due to the opening of the LCD screen for viewing, turning it off can increase the battery backup time by two or three times; fourth, try to use the continuous shooting function as little as possible. Most of the continuous shooting functions of digital cameras use the built-in buffer memory to temporarily save digital photos. If these caches are used frequently, a lot of power is required. Therefore, reducing the use of continuous shooting and movie movie shooting functions is very helpful for power saving.
In order to prevent the problem of power loss, it is necessary to clean the battery. Keep the contact points at both ends of the battery and the inside of the battery cover clean. Use a soft, clean dry cloth to wipe lightly when necessary. Never use clean or chemical solvents to clean your digital camera, battery, or charger. If you plan to not use the digital camera for a long time, you must remove the battery from the digital camera and fully discharge it (some chargers have this function, if there is no short-circuit with a small resistance, try to discharge the battery) In a dry, cool environment, and do not store the battery with ordinary metal objects. When storing fully charged batteries, be sure not to put them in leather bags, pockets, handbags or other containers with metal objects to prevent short circuits.
