IMPORTANT NOTE: This FNB-83xh is an exclusive-design product, incorporating high-capacity SANYO cells. The casing is custom-tooled to accomodate these battery cells, and the battery pack is 1/16" thicker than a standard OEM battery. The fit on the radios is excellent. The battery fits under the belt clips just fine. If you have a desktop charger with a tight pocket (where the radio & your original battery together leaves no extra room in front of charger pocket), then the FNB-83xh and your radio may not fit in your charger together. The battery CAN be charged separately (alone) in the charger pocket. If you wish to charge battery and radio together, and your charger is the tight pocket style, then the highest-capacity battery available for that purpose is the FNB-83x (7.2v 2000mAh NiMH).
