ENCLOSED CLAD LEAD STORAGE BATTERY

摘要

PURPOSE:To improve the discharge capacity thus to improve the service life by employing a tube of thin composition thereby realizing the electrical resistance or the quantity f water supply suitable for electrolyte gel. CONSTITUTION:A tube 2 having thin composition is employed to prevent separation of gel at the tube section thus to improve the discharge performance of an enclosed clad lead storage battery employing a lead alloy core metal 1 which will never lower the hydrogen overvoltage considerably. The tube has the electrical resistance in dilute sulfric acid having the specific gravity of 1.200 under the temperature of 25 deg.C lower than 0.002 ohm.dm<2> and the water pass quantity in the water under the pressure of 10cm water pole higher than 200cc/min.cm<2>. Consequently, the discharge performance is never damaged while the active material is never softened nor dropped resulting in improvement of the service life.
