One may think that their new digital camera, whether it is the new Canon EOS 7D, the Olympus EP-1, or the Nikon D5000, is a great self-contained image machine. But have you ever considered whether there may be parts of your digital camera that are consumable?  

Initially the first response would be no. Unlike a printer that has ink or toner you would think that a digital camera would not have any consumables.  

Upon further review one might say that the memory is the consumable. While memory can be consumed it also can be cleared and reused so would not meet the definition of a true consumable if you agree with the most common definition: Consumable -liable to be used up or depleted  

Lithium ion batteries became popular with the portable consumer electronic market because of their high energy-to-weight ratio's and ability to hold a charge for long periods of time when not being used. Because of their use in aerospace and defense government, architects' work continually on improving the technology. As with all technology, improvements come quick so the few disadvantages are likely to soon be resolved.  

Currently the major concern with lithium ion batteries, especially in digital camera use, is with aging. Some deterioration is noticeable after one year. Large percentages fail after 2-3 years.  

The new lithium ion improvements favoring enhancements in chemical combinations are being reported every 6 months or so. So the life of batteries is sure to be extended soon.  

You may have heard that you should totally discharge the battery with subsequent full recharges to prolong your battery life. The truth is that batteries favor partial use with partial charge on most days saving the full discharge and recharge for once every 30 charges so it can recalibrate and synchronize the fuel gauge with the battery's recollection of charge. If this synchronization is ignored the battery will become less and less efficient.  

So Yes, the battery can be considered a consumable. To ensure your digital camera is always ready and available a second lithium ion battery should be considered and is recommend. For additional information on the latest digital camera equipment visit Online Digital Camera Reviews your trusted online resource.
