First you have the mixtures of manganese dioxide, graphite, and an electrolyte. That mixture dell Latitude D830 battery is ground down and aged. Then the mixture is put into a pressed tablet. The tablets are then inserted into a steel can. The steel can and the mixture becomes the cathode of the alkaline dell MM165 battery. Then they put an indent at the top of the can and sealant is placed above it. They do that so the battery doesn't leak.
The next step is to add the anode. The anode is made up of mostly zinc and some other amterials. They put a separator in the can so the anode does not touch the other mixture. Now that the two mixtures are in there, the battery will actually work now. Since the can is not sealed yet, the dell YD626 battery would not last long at all. So the next thing is to seal the battery closed. This will make sure the battery will last long and bring good performance.
The seal is made of many different things. The first is a brass nail, which is the current collector, there is a plastic gasket, a stee washer, and a metal cap to top it off. Now there is a top that gets welded on to battery. This way the dell 312-0393 battery is safe to hold and touch. The last step is to putthe label on, sea it up, and ship it off. There is your battery.
