Tis a battery!

Without these your camera probably won't work, if it does, let me know and I'll buy your camera.

Does the job


from Atlanta, GA  -  Photo Enthusiast

The battery is for an SD14 and works very well. It seems to hold a charge very well and charges quickly with the SD14 charger included with the SD14 kit. I have not had any issues with the battery in 30 days of continuous use.

Questions about this item:

Shopper  Why Did You Choose This?
THOMAS J S  Spare battery for Sigma SD15 DSLR. I prefer to use the Sigma brand for this.
VERONICA C  this is veronica yes. I'm looking for a battery, a battery grip, and a hot shoe flash for a sigma sd1?
PAUL U  I recently purchased two Sigma BP-21 packs for my SD14 because I had previuosly purchased two third party batteries which proved to be substandard. The Sigma BP-21 that came with the camera even after three years of use still performs FAR better then the off brands. The two new Sigma BP-21s have proven to provide me with enough power for well over 300 image captures from each battery. Would I recommend the purchase of Sigma battery packs over off market battery packs? Absolutely, even though the off markets were a third of the price they provided far less images per charge. Shopping with Adorama has been a pleasure from the veery begining. They have been honest and easy to deal with at all times I regularly recommend them to family and friends. Stick with the name brands as much as you can and you will avoid disappointment. I will comtinue to shop with Adorama in the future.
VERONICA C  does this battery work on the sigma sd1 and do you have a battery grip , and a hot shoe flash that will fit this camera?
SONJA R  Veronica, I have the SIGMA SD-14 and it uses the Sigma BP-Lithium Battery. I have the battery charger and cord that came with the camera. About the flash, I have never considered the external and don't know if it can be used with this camera. One more thing I'm not much help on -- have no idea what the battery grip is. See my many photos on facebook -- most have been taken with this camera and I'm very pleased with it.
