An information collection and storage system and method wherein pulses representing sensed information are counted and wherein resulting pulse counts are written into a volatile random access memory which forms a part of a detachable battery powered memory pack. The memory pack is selectively removable from the system and has a rechargeable battery which supplies the sole source of operating power for preserving the data stored in the volatile memory both when the memory pack is connected in the system and removed from the system for transit to a data read-out center.
