Abstract

PURPOSE:To enable to monitor the life of a lead storage battery without measuring the specific gravity of electrolytic solution by measuring the elongation of the top of a positive plate by an optical fiber bundle and an indicator attached on the top of a negative plate. CONSTITUTION:A lead storage battery 1 consists of a battery jar 2 and a lid 3, and positive plates 4, negative plates 5 and liquid absorbing separator 6 are inserted in the electrolytic tank 2, where most of electrolytic solution is held in the separators 6. An optical fiber bundle 7a serves as an image guide for observation and an optical fiber bundle 7b serves as a light guide for illumination, and both an object lens 11 and an eye piece 12 are provided. An indicator 10 is attached to the top 9 of a negative plate. By measuring the elongation 13 of the top 8 of a positive plate by means of the optical fiber bundles 7a, 7b and the indicator 10, life of the lead storage battery can be monitored and, when the elongation of the positive plate reaches 10% or more, significant drop of the battery capacity can be known.

ことができないという欠点があった。Prior Art and Points of Interest Conventionally, the lifespan of lead-acid batteries has generally been determined by measuring the specific gravity of dilute sulfuric acid, which is an electrolytic solution. However, in so-called sealed lead-acid batteries, in which the electrolyte is essentially non-fluidized, there is no free electrolyte whose specific gravity can be measured, so it is not possible to determine the battery life from the specific gravity of the electrolyte. The drawback was that it couldn't be done.
