PURPOSE:To prevent the performance deterioration without requiring complicated maintenance for maintaining the battery characteristics by applying the chemical conversion treatment to a retainer-type lead storage battery then storing it under a condition that an impedance means is connected between both negative electrode and positive electrode terminals. CONSTITUTION:An electrode group stacked with a positive electrode plate and two negative electrode plates in turn through a separator 6 made of glass fibers is inserted into a battery jar 7 made of resin. Next, a sulfuric acid electrolyte is injected, and a battery jar cover 8 fitted with negative electrode and positive electrode external terminals 9, 10 is fixed to obtain a lead storage battery. An impedance means is connected between the negative electrode and positive electrode terminals of a storage battery 1 for storage after the chemical conversion treatment. This impedance means is set to such a size that the battery is discharged at a current value less than that for five-hour rate (0.2C). For example, a resistor of 20OMEGA corresponding to the 0.1C current is connected. Accordingly, complicated maintenance is not required and the battery performance deterioration can be prevented. |
