I'm selling a third party battery and charger for Canon 1D cameras. I never used it (just had it in the bag as a backup), and then sold the camera. This is a cheap alternative to the $200-ish OEM battery and hideously priced charger. Will fit the Canon 1D Mark III 1Ds Mark III 1D Mark IV 1DX 1D X and 1DC or 1D C .
