Maha, better known for their battery chargers has introduced a new business line called "Powerex". Powerex has introduced a range of four Lithium-Ion / Lithium-Polymer rechargeable battery packs which are directly compatible with several digital camera models which take proprietary designed packs. The four packs are the MH-BP511 (Canon G1, G2, D30, D60 etc.), MH-NP80 (Fujifilm / Toshiba / Kodak), MH-ENEL1 (Nikon Coolpix 775, 885, 995, 880, 885, 5000 etc.), MH-NB1L (Canon PowerShot S100, S110, S300 etc.). These packs are completely compatible and have either the same or higher capacity than the packs they replace.
