Coming to next one in line, NiMH (Nickel Metal Hydride). This is a battery that is perhaps most frequently under use for not only digital cameras, but also for other sophisticated devices like laptop computers! This has advantage of being cheap in price due to fact that it incurs cheap manufacturing costs, and thus a choice for many users! But this does have problems of memory effect, and much more maintenance and care is required while handling this kind of battery. Another such battery is NiCAD (Nickel Cadmium) Battery. This is perhaps belonging to one of older cell types generally available for older laptops and electronic devices. These batteries or cells have an aptitude for handling high power loads, and therefore is more frequently found in handy power tools and devices that require more amounts power to work efficiently and perfectly. Yet again, these batteries too have problems of memory effect, and much more maintenance and care is required while handling this kind of battery.
Apart from different batteries themselves, selection should be based upon charging techniques and different charges available for all these digital camera batteries. Latest batteries come handy with charging free techniques too! So care needs to be taken in this area also, depending upon requirements of user.
With all vivid conversation regarding hearts of digital cameras, their batteries, it is expected for every person going through lines to have grabbed a significant amount of information in dealing with intricacies of purchase, and thereby also augment ability of person in using such a sophisticated device as a digital camera with a proper battery!
