MRB400 1.35V Zinc Air Battery Z400PX PX400 EPX400 RM400, Exell Battery, Mfr#: MRB400

Exell MRB400 1.35V Zinc Air Battery Z400PX PX400 EPX400 RM400. Replacement for: PX400 / EPX400 / RM400 / H-B / V400PX / E400N / PM400R / KX400 / T400N The PX400 is is a discontinued Mercuric Oxide coin type cell that was commonly used in cameras and is now banned because of toxicity and environmental fears. The original PX400 mercury cell produced 1.35V. There are two possible replacements for this PX400 cell: * the equivalent silver oxide cell, the S400PX. * the equivalent zinc air cell, the WeinCELL MRB400. There are no alkaline cells manufactured of this size and shape. Another PX400 replacement is a zinc air battery. The WeinCELL MRB400 is a custom zinc/air battery designed to replace banned mercury batteries. WeinCELLs deliver the same 1.35 V voltage and stability of output as did the mercury PX400 batteries so there is no need to adjust your exposure. The WeinCELL MRB400 batteries last much longer than hearing aid batteries, some times up to a year. To achieve this longer life, the MRB400 used a proprietary electrolyte and has only two small air holes, instead of the 7 larger holes found in standard hearing aid batteries. • • •
