Acidity condition indicator for battery, e.g. lead accumulator, comprises visible rod and rod retaining and fixing holder and is prepared by two-component injection molding

摘要

In an acidity condition indicator (16) for a battery (11), comprising a visible rod (14) and a holder (12) for retaining the rod and fixing the indicator to the battery housing (10), the rod and holder are prepared by two-component injection molding, the holder being injected around the rod. Independent claims are included for: (1) a battery with an acidity condition indicator as above; (2) the production of the acidity condition indicator, including the stage of producing the rod and holder by two-component injection molding; and (3) the production of a battery, including the stages of producing an acidity condition indicator as above and connecting the indicator to the housing and the other components of the battery.
