Sigma BP-21 Li-Ion Battery for Sigma SD-14 Digital SLR Camera

The Sigma BP-21 Rechargeable Lithium-ion battery provides enough power to the SD14 digital camera to shoot approximately 500 images on one full charge. It takes about 120 minutes to fully charge with the BP-21 battery charger. Your Sigma digital camera is like a mini-computer with a lens. The battery must power the LCD monitor, the motorized zoom autofocus mechanism, metering system, electronic flash and more. A spare rechargeable battery is an essential accessory. No power, no pictures. With constant shooting, flash usage, image playback, especially when you have access to additional memory, your standard battery alone will not usually be sufficient. Providing an extra 1500 mAh of power, this spare BP-21 will not put constraints on how you want to shoot. A battery loses power in cold weather and can become too cold to operate the camera. Keeping a spare battery warm in your pocket to maximize battery power and periodically switching the cold battery for the warm one can significantly enhance battery performance.
