Speaking of some of the above, played a decisive role, is the battery cell. A powerful companies, should disclose information on their use of batteries. First-class batteries, a Panasonic, Sanyo, Mitsibish, Hitachi and so few; second point, there are GS, GP, etc.; once again, it is the domestic HYB, BAK, LISHEN, BYD, etc.; most times is is unclear the number of unknown brand. When everyone in the optional battery, as long as is clearly the name of factory batteries, they will not lose fooled. Lithium and nickel-metal hydride battery comparison In the purchase of digital camera batteries, the sales staff will recommend lithium batteries for consumers, because lithium batteries have high energy, small size, etc., but the lithium battery of choice for digital cameras is really it? Misunderstanding lithium battery: lithium battery energy density, small size, is the first choice for digital camera power supply. 1, the average charging time from the flash analysis, the use of lithium batteries have an advantage. Discussion: from the use of terms, digital camera viewfinder, exposure, image processing, playback and storage when they have different power consumption characteristics; from the main power devices to analyze, LCD screen, flash, image sensor and processing engine is power-hungry, but basically is unexpected type, only in the moment of the work of high current, usually quiescent current is very small. This determines the power consumption characteristics of a digital camera, you need to have a sudden high current power supply capacity. From this point of view, relatively low internal resistance of battery is more suitable for digital cameras, digital cameras, it can significantly improve the response speed. The average charging time from the analysis of the flash, using lithium camera ahead, usually only 3 seconds, while the use of Ni-MH battery models tend to be longer than 6 seconds.
