Car battery assembly considerations

March 30, 2024

Assemble the battery should pay attention to the following matters:

First, the welded positive and negative plate groups are interdigitated and then fixed together on a special jig. Gently poke the plates apart and install the separators one by one from the center to the sides. The grooves of the separators should face the positive plate, and the glass wool of the combination plates should also be attached to the positive plates. The partition should be installed upright.

Secondly, put the assembled plate group into the single compartment of the shell, and the elasticity should be appropriate. If you feel too tight, you can use a special wide face clamp to slowly compress; too loose, you should add pad spacers. Note that the positive and negative directions of the individual cells must be staggered.

Third, install the battery cover. Place a protective stencil horizontally on the upper part of the grid and install the battery cover. The height and position of the cover should be adjusted properly. If there is loose, it can be plugged with an asbestos rope around it. The gap between each pole and the pole hole of the battery cover should be tight, otherwise it must be sealed with asbestos rope or lead bush. Otherwise, the sealing glue can easily flow into the battery.

4. Welded joints and poles, first welding the lead bushes and pole piles of the battery cover, and then welding the poles and joints. Welded poles shall be moulded so that the molten alloy is filled in the pole piles and the piles are removed after cooling. When the poles and joints are welded, they should be melted from the center of the pole to the surrounding area, and the movements should be quick and accurate. Otherwise, welding prongs may easily occur. In order to make the joints beautiful, some rosin can be added during welding to increase the fluidity of the alloy.

5. Close the mouth, heat the sealed mouth to 190 - 200°C, infiltrate around the lid, pour 2/3 first, then add water until the seal is flush with the upper plane of the lid, and then smooth with an electric iron. (Do not use torches.) After sealing, the adhesive layer is acceptable without bubbles or cracks.
