Problems such as breakage of the portion and increase in electric resistance occur. In order to prevent such inconvenience, it is essential to inspect the connection state of the inter-cell connection part. Conventionally, however, it is necessary to visually inspect the appearance and airtightness, or to short-circuit the electrode plate due to the outflow of abnormally molten lead from the connection part. The next abnormality is generally detected by a short inspection, and the internal state of the connection is not inspected.

The two straps are welded through the through holes provided in the partition. Next, a step of inspecting the connection state of the inter-cell connection by providing a current between the two straps and measuring the voltage drop value or measuring the resistance value between the two inter-cell straps is provided. If there is a gap or poor connection between members inside the cell-to-cell connection, the electrical resistance will increase, resulting in an abnormal voltage drop or abnormal resistance due to ohmic loss. Or By detecting this, the connection between cells can be inspected more reliably and nondestructively than in the past, and a good lead-acid battery can be manufactured.

In FIG. 1, reference numerals 1 and 2 denote straps, reference numeral 3 denotes an inter-cell connection portion, reference numeral 4 denotes a battery case partition wall, and reference numerals 5a and 5b denote extruded electrodes for welding. As the welding operation, for example, the partition wall through-hole diameter is 10 mm.
If it is on the order, it can be performed at 5500 to 6000 A × 10 Hz. FIG. 2 shows a schematic correlation between the welding current and the voltage drop at that time. If the current value is small, the melting of the strap is insufficient, so that the electric resistance at the portion is large and the voltage drop is large. Conversely, if the current value is too large, welding failure occurs due to excessive melting of the strap, resulting in a large voltage drop.

By measuring the resistance value between the two straps, the state of the connection part is checked by the step of checking the connection state. Needless to say, there is no essential difference between the voltage drop value and the resistance value, and it can be appropriately selected. In this embodiment, a method of detecting a voltage drop value when a predetermined current flows is adopted.

できる。FIG. 3 shows the relationship between the voltage drop value and the connection strength when the current value is 20 A. The connection strength is determined by a threading torque inspection method. As is clear from the figure, there is a clear correlation between the voltage drop value and the connection strength. By comparing the voltage drop value when a predetermined current flows with the predetermined value, the connection between cells can be performed. It is possible to detect a gap inside the portion, a joining failure of the members, and the like. In the case of the lead storage battery in this embodiment, it is known that there is no problem in the connection portion if the torque value is 50 or more. As is clear from the figure, it was confirmed that the torque value was exceeded when the voltage drop value was 0.3 mV or less. Therefore, in the case of the present embodiment, by selecting the storage batteries with the reference value being 0.3 mV, only those having a good connection state can be flowed to the next step.
