Digital cameras suck up battery power

Digital cameras suck up battery power, and as time has passed their size is getting smaller, and subsequently has created a constant need to develop batteries tiny enough to fit into a camera and yet have the ability to supply power for a realistic time period

Two distinct boundaries exist in the battery types digital cameras.

Standard Mass Produced Stock Batteries

The first type of batteries are those that are acknowledged as being mass produced, most often AA, CR2, and CR-V3 batteries, although AAA batteries are used to operate a handful of small cameras. CR2 and CR-V3 batteries are lithium based, and designed for solo use. Also they are frequently seen in camcorders. AA batteries are the most common; conversely, the non-rechargeable type alkaline batteries only providing enough juice for just a very limited time period in the majority of cameras.

A majority of photographers utilize Nickel metal hydride AA batteries (NiMH) in their place, which afford an adequate power supply, plus the're rechargeable. These NIMH types of batteries do not supply as much energy as lithium ion batteries do, and also they more likely to become discharged when not in use. They come in varied ampere-hour (Ah) or milli-ampere-hour (mAh) rankings, which has a direct affect on how long they hold up while in use. Most often mid-range consumer cameras and a few low end versions utilize standard mass produced batteries; while just a handful of DSLR cameras can use them (the Sigma SD10 for example). Rechargeable RCR-V3 lithium-ion batteries also are offered as a substitute for non-rechargeable CR-V3 batteries.

Custom Camera Manufacturer Batteries

These are batteries created to a camera makers custom requirements, and may be either OEN of aftermarket replacement parts. Just about all custom proprietary batteries happen to be lithium ion type. Although they only endure a limited amount of recharges prior to the start of battery life degrading most often as much as 500 cycles), but they offer significant performance in relation to their size. The bottom line is that at both extremes of the spectrum of both high end pro cameras plus low end consumer versions are apt to employ lithium ion batteries.

The first is batteries that are an established off-the-shelf form factor, most commonly AA, CR2, or CR-V3 batteries, with AAA batteries in a handful of cameras. The CR2 and CR-V3 batteries are lithium based, and intended for single use. They are also commonly seen in camcorders. The AA batteries are far more common; however, the non-rechargeable alkaline batteries are capable of providing enough power for only a very short time in most cameras.

Most consumers use AA Nickel metal hydride batteries (NiMH) (see also chargers and batteries) instead, which provide an adequate amount of power and are rechargeable. NIMH batteries do not provide as much power as lithium ion batteries, and they also tend to discharge when not used. They are available in various ampere-hour (Ah) or milli-ampere-hour (mAh) ratings, which affects how long they last in use. Typically mid-range consumer models and some low end cameras use off-the-shelf batteries; only a very few DSLR cameras accept them (for example, Sigma SD10). Rechargeable RCR-V3 lithium-ion batteries are also available as an alternative to non-rechargeable CR-V3 batteries.

Proprietary Batteries
Batteries built to a manufacturer's custom specifications, and can be either aftermarket replacement parts or OEM. Almost all proprietary batteries are lithium ion. While they only accept a certain number of recharges before the battery life begins degrading (typically up to 500 cycles), they provide considerable performance for their size. A result is that at the two ends of the spectrum both high end professional cameras and low end consumer models tend to use lithium ion batteries. updated article Mar 28, 2011

Effective January 1, 2008, you may not pack spare lithium batteries in your checked airline baggage. On January 1, 2008, the U.S. Department of Transportation (DOT) implemented a new rule for airline passengers traveling with spare (uninstalled) lithium batteries as follows Passengers are prohibited from carrying spare lithium batteries in checked baggage. In carry-on baggage, passengers may still carry any number of smaller lithium ion batteries (those with 8grams or less of equivalent lithium content) and smaller lithium ion metal batteries. The following lithium batteries can be carried for air travel. A battery's electrical connections (also called contacts or terminals,) must be protected from contact with metal or other batteries that may cause the battery to short-circuit. ✓
