ABSTRACT:
A rechargeable battery pack includes at least a power cell and a substantially sealed housing adapted to permit venting therefrom of increased internal housing pressure while normally maintaining a substantially air-tight closure. A novel charge status indicator for integration with the battery pack provides a positive indication of the substantially fully charged status of the power cell.
