PowerEx (Maha) has announced three new Lithium-Ion battery packs designed to be a cheaper option to the camera manufacturer branded packs. These batteries are essentially identical to the supplied battery and are fully compatible with both camera and charger. In some cases the PowerEx batteries actually have more capacity than the standard battery. The MH-FM50 is compatible with Sony cameras which used the NP-FM50 battery, the MH-ENEL3 is compatible with tne Nikon D100 and the MH-NP200 is compatible with the Minolta DiMAGE X, Xi and Xt. These batteries are in addition to the wide range of compatible (cheaper than branded) Lithium-Ion batteries PowerEx already have.
