|An intelligent camera deserves an intelligent battery, and the EOS-1Ds Mark III is at the head of the class. Smaller, lighter, smarter and more powerful than its Ni-MH counterpart, the Lithium-ion battery delivers up to 1800 images per charge*. It also communicates vital information about itself via the LCD panel display and Battery info screen, including battery type, capacity, shutter count and rechargeable performance.
||To avoid the problem of inaccurate display of the battery level caused by repeated charging and discharging of the battery, the EOS-1Ds Mark III alerts you when the battery requires recalibration. This helps the battery maintain accurate information of its actual capacity, essential for proper display of the battery level by the camera.
