Film coatings ranging from 0.100 to 76 μm can be applied in a single operation. The coating thickness is uniform, even on irregular surfaces. Desired contact points, such as battery contacts or connectors, must be covered with an air-tight mask to prevent the parylene from coating the contacts. Applying parylene is a batch process that does ...
General Motors, and other automobile manufacturers, have also begun using side-post battery terminals, which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached. These side posts are of the same size and do not prevent incorrect polarity connections.

[44] If the battery is overfilled with water and electrolyte, then thermal expansion can force some of the liquid out of the battery vents onto the top of the battery.
Volkswagen and a technology partner have mastered a battery manufacturing process called dry coating which if scaled up could cut the cost of cell production by hundreds of millions of euros a ...

The silver-plated wire coating cold-welds to the gold. If corrosion occurs, it occurs on the outside of the wire, not on the gas-tight contact where oxygen cannot penetrate to form oxides. A correctly designed wire-wrap tool applies up to twenty tons of force per square inch on each joint. The electronic parts sometimes plug into sockets.
