SPECIFIC GRAVITY OF ELECTROLYTE AND LEVEL DETECTING DEVICE FOR LEAD-ACID BATTERY

摘要

PURPOSE:To ensure not only freedom from the indication of abnormality even in the substantial fluctuation of an electrolyte level, but also the proper indication of replenishment timing and enable the application of the device in the title even to a battery type having a different a maximum liquid level position by providing a plurality of silver sulfate dispersion holes at the lower part of a cylindrical part, dislocating the holes from each other within the predetermined range and arranging the holes in upper and lower levels. CONSTITUTION:Silver sulfate dispersion holes 25 and 26 at the lower part of a cylindrical part 13 are made plural, dislocated from each other within a range of 0 to 120 deg. and arranged in upper and lower levels. When an electrolyte decreases and a magnetic float 22 comes down, the float 22 comes near a lower stopper 26 and turns off a reed switch 23. As a result, a detecting monitor indicates that a lead acid-battery is abnormal. When the electrolyte is at a position near a maximum liquid level and the battery discharges, thereby reducing the specific gravity of the electrolyte to the predetermined level, the magnetic float 22 comes down and nears the upper end of the lower stopper 26. As a result, the reed switch 23 is burned off and the monitor indicates that the lead-acid battery is abnormal.
