POLARITY INDICATING APPARATUS FOR BATTERY

摘要

PURPOSE: A polarity-indicating apparatus is provided to improve coherence to prevent damage by external impact, and to easily and simply conduct measurement using a power input and output terminal for inspection. CONSTITUTION: A polarity-indicating apparatus for a storage battery comprises a terminal which inputs and outputs power from a storage battery; and a polarity plate(10) which displays polarity of power from the outside of the terminal and is fixed to the cover of the storage battery. The polarity plate comprises a guide part(12) which consists of a wall side upwardly protrude upward from a hole(13); and an expansion part which has one or more lower protrusions downward from a lower side extended from the lower side of the guide part to a plate. The guide part comprises one or more insertion holes(122) which are formed on the wall side.
