Highlight:
Digital cameras' power demands can quickly drain batteries, which means that you need to find batteries that will stand up to the rigors of these hungry devices. Alkaline batteries can quickly be run down in a digital camera and need to be thrown out once they are spent. Thus rechargeable Li-ion, NiMH, or NiCad batteries are a much better choice for digital cameras.

Summary:
* Being such a crucial task as if searching for a good heart for a human being, perhaps the most tedious thing about digital cameras is the quest for their battery consumption and thereby finding a suitable one for any particular one.
* Leaving aside the ever power thirsty LCD screens and flashes, the digital cameras themselves exhaust batteries much faster than film cameras, due to their state of the art electronic designs and intricate circuitry.
* Many digital cameras run from AA cells, around 4, and can even drain a set of alkaline cells in less than 1 hour of working!
* For example, the Kodak DC120 draws about 210mA during start or switch ON, but progresses to around 1.3A with the association of the LCD fully working and can go ahead to about 2.1A while picture taking and after it too.
* It is light in weight and currently available for many commercial uses and thus being so the Li-ion (Lithium Ion) battery type is becoming quite popular.
* This has an added advantage of being able to endow with more power than any of the other main cell types available.
* It is also free from the problems of memory effect, hat some battery types do have, and maintenance is least in this type of battery.
* 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 the problems of memory effect, and much more maintenance and care is required while handling this kind of battery.
* Apart from the different batteries themselves, the selection should be based upon the charging techniques and the different charges available for all these digital camera batteries.
