What type of battery?

Source: 2020 - 03 - 26 thy hits: what type of battery? Digital camera battery is needed to stay afloat. In general, the digital camera can choose dry cells, alkaline zinc manganese battery, nickel cadmium battery, nickel metal hydride batteries, lithium ion battery and lithium battery as a power source. Alkaline zinc manganese battery this battery is the best. 5. 电池在市场上,我们可以很容易地购买。 The battery is easy to buy in the market. Their battery of digital camera mostly is the underlying product, without any special skills and data modification. Because there are many different kinds of the products in the shop, the user does not have to worry about the price of the battery, however, because of their limited skills, their power and battery life is much lower than other batteries. Sometimes, its power is not enough to drive a digital camera, and even affect the digital camera. Early nimh battery is nickel cadmium battery substitutes, compared with the nickel cadmium battery, nickel cadmium battery advantage has become increasingly apparent. Greatly reduces the nimh batteries' recall effect, it is more convenient, the use of nimh battery service life is longer, Up to 1000 times) 。 In addition, the nimh batteries also has large capacity, large depth of discharge, resistance to overcharge, over discharge, short charging time etc. Ni-mh battery is the most important is no longer toxic heavy metals are used as the data, can eliminate the pollution to the environment. At the same time, on the electrical characteristics is similar with nickel cadmium battery, in the actual application can completely replace the nickel cadmium battery, don't need to make any changes to the camera. Nickel metal hydride batteries are not perfect, of course, there are also some disadvantages. The high temperature characteristics is poorer. Environment and the high temperature of 45 degrees Celsius above zero degrees Celsius under low temperature environment, the nimh battery cannot work normally, even at the bottom of the camera could not be started. In addition, the battery self-discharge rate is relatively high, storage after a period of time will find the power is decreased obviously, there is also a nimh batteries have subtle effect of recall. Lithium-ion batteries, lithium-ion battery price is relatively high, but it has a light weight, large capacity, large energy density, compared with nickel metal hydride batteries, lithium ion battery is relatively simple, energy is higher than 60%. As a result, production and sales of lithium ion batteries are gradually replacing nickel metal hydride batteries, become a digital camera to use one of the main battery. In addition, the lithium ion battery has' recall effect is small, do not contain toxic substances, etc, as well as the extensive use of the important reasons. Lithium ion battery and lithium battery technology, the function is good, but the price is a bit high, use is more exquisite, messy, especially lithium ion battery charger must be 'special', it can't compatible with other battery charger. Alkaline zinc manganese battery, although the unit price is low, consumers can afford to buy, but its service life is short, the long-term use of the average consumer is difficult to bear the cost. Cadmium nickel battery, nickel metal hydride battery, by contrast, is now on the production technology is mature, the battery price is reasonable. If you used a mismatch of battery or not saving, the battery will run out before you take too many pictures. The following method can save battery consumption: the first, try to avoid unnecessary zoom operation; Second, to prevent the frequent use of flash, flash is a kind of large power consumption equipment, we try to prevent the use; Third, when adjusting the composition, the viewfinder is better than LCD. Since most digital camera by opening the LCD screen to view will consume more energy, so can increase the number of batteries can be used to close them one or two times. Fourth, use less as far as possible the continuous function. Most digital cameras use the built-in cache to temporarily store digital photos. If the frequent use of the cache, they need a lot of power. Therefore, reduce the use of continuous dynamic impression taken function, is of great help to save electricity.
