Digital camera battery needs to maintain normal operation. Under normal circumstances, a digital camera can be used dry batteries Laptop Battery, alkaline zinc-manganese batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries and lithium batteries as its power supply.
Alkaline zinc-manganese batteries
This battery is very easy to buy in the market, get 5 batteries, they have not been of special materials and technological innovation, the use of such batteries are mostly at the bottom of digital camera products. Because a wide range of marketing, so the user need not worry about the price of the battery, but also because of technology, common, its power supply and staying power is far inferior to other than a few batteries. Sometimes, his power is insufficient to pull the launch of digital cameras and even IBM FRU 92P1137 Battery digital cameras will be affected.
Ni-MH battery
This battery is an early alternative to nickel-cadmium batteries, as opposed to nickel-cadmium batteries, nickel-metal hydride batteries have a more compelling advantages. It greatly reduces the existing nickel-cadmium battery "memory effect", which makes the use of nickel-metal hydride batteries more convenient and more long-term cycle life (up to 1000 times). In addition, the Ni-MH battery also has the power of high capacity, large depth of discharge, overcharge and over-discharge resistance, charging time is short and so obvious advantages. The most important thing is to use nickel-metal hydride batteries are no longer toxic heavy metals as a material that can eliminate its impact on the environment. At the same time, in the electrical properties with the nickel-cadmium batteries are similar, in practical applications can replace IBM 02K6651 Battery nickel-cadmium batteries without the need for any transformation of the camera.
Of course, the Ni-MH battery is not perfect, it also exist some disadvantages. It is relatively poor high-temperature properties, in temperatures above 45 degrees Celsius environment, as well as 0 degrees Celsius below the low-temperature environment, the nickel-metal hydride batteries will not work, or even impossible to start the camera; In addition, the battery self-discharge rate is quite high , the storage period of time will find it significantly reduced the electricity; there is a nickel-hydrogen batteries also exists a slight memory effect.
Lithium batteries
Lithium-ion battery IBM 02K6928 Battery prices higher, but it has a light weight, large capacity, energy density advantage compared with the nickel-metal hydride batteries, lithium-ion batteries are relatively portable, while the energy is higher than 60%. Because of this, lithium-ion battery production and sales are increasingly more than nickel-metal hydride batteries, a digital camera is now mainly used as one of the battery. In addition, the lithium-ion battery is almost no "memory effect" as well as the advantages of non-toxic substances is also an important reason for its wide range of applications.
Lithium-ion batteries and lithium batteries state of technology, performance, relatively well, only slightly higher prices, pay attention to use relatively complex, in particular, lithium-ion battery IBM 02K6620 Battery charger must be "dedicated", it can not charge the battery with other compatible. Alkaline zinc-manganese batteries, although the price is low, consumers could afford, but its short life, long-term use of ordinary consumers can hardly bear the cost. In contrast, nickel-cadmium batteries, Ni-MH battery is more mature in manufacturing technology, the price more reasonable battery.
If you are using does not match, or not pay attention to save the battery IBM 02K7039 Battery, the battery will not shoot you when you run out of a few pictures. The following approach can save the battery usage: first, try to avoid using unnecessary zoom operation; second, to avoid the frequent use of flash, flash is a big power, we try to avoid using; third, when adjusted better to use the viewfinder when the picture composition device, rather than using the LCD. Because most digital cameras are due to open the LCD viewfinder and consume more power, turn it off can increase two to three times the battery standby time; Fourth, minimize the use of multi-shot. Most of the multi-shot digital camera built-in cache to use the fuselage to temporarily save the digital photos. If regular use of these caches, then the required power is very large. Therefore, IBM ThinkPad X60 Battery reducing the use of Continuous and dynamic image video capture function, saving of much help.
