Case study dry cell battery

Where steam is available, a flame should, however, never be used. Batteries with high gravity or hot electrolyte have burned and carbonized separators, turning them black and rotting them, the negative paste becomes granulated and is kept in a soft condition, and gradually drops from the grids on account of the jolting of the car on the road.

Removing a few separators will permit you to separate the groups before removing the rest of the separators. Some digital meters set the range automatically. Why did one of the terminal connectors get loose and make a slopper.

If the post seal consists of a lead sealing nut, this may be removed now. However, trouble often arises in a battery whose negatives still have considerable capacity, and such negatives may safely be used with new positives. Fold this in half by bringing the ends together; cut a taper on the crease and unfold it again to produce a strip with a narrow indentation in Case study dry cell battery middle.

In this way, put in the six separators, with the grooved side toward the positives, working outward in both directions from the center, Fig. To make the test in this way. However, batteries of different sizes may have the same voltage.

Once this material becomes bulged nothing but pressing will put it back where it belongs, and until it is pressed back into the grids the plates are in a poor condition for service. First look over the ignition system and spark plug for trouble, and also make sure that the carburetor is receiving fuel.

When making an installation, it is always a good plan to carry' the following material for taking care of spillage and broken jars: Handle every cell of a battery that comes in for repairs in the same way, even though only one dead cell is found, and the others are apparently in good condition.

One pilot cell contains the pilot ball for determining the end of the charge, and other pilot cell containing the ball for determining the end of the discharge. Here again the labeled boxes described on page come in handy. This sketch should be made on the tag -which is tied to the battery.

It should be one which is not very cold in winter, as a cold battery is very sluggish and seems to lack capacity. Continue the charge until the electrolyte clears up, and its specific gravity stops rising and the plates have a normal color' over their entire surface.

New plates are required.

You may also put negatives back in jars from which they were taken, and fill with water. Place the case so that this mark is toward you. These processes are slower at lower temperatures and so it is to be expected that the internal resistance of the cells should increase with decreasing temperature.

This should be lone very carefully, however, and the straightening done. Step 1 Strip both ends of each length of wire and install an alligator clip on each end. Suppose the battery showed poor capacity on test, what would you do?. SIC Case Studies - 3-August Case Study: Eveready Battery Company Location: Asheboro, NC (Randolph County) N.C., which manufacture and packages Energizer brand dry cell batteries.

It offers a pictorial step-by-step. Anode: Zinc inner case Cathode: graphite rod E = V In the alkaline dry cell (alkaline battery), the acidic ammonium chloride of the regular dry cell is replaced by basic (alkaline) potassium hydroxide.

e) Study all battery manufacturers’ specific precautions and recommended rates of charge while charging. 4) DC AND AC CONNECTION PRECAUTIONS a) The Minn Kota charger will only charge 12 volt 6 cell lead acid batteries. DO not use this battery charger for dry-cell batteries that are commonly used Fresh water and soap should be nearby in case battery acid contacts skin, clothing, or eyes.

3. Wear eye protection and protective clothing. Study all battery manufacturers' precautions such as removing or not removing cell caps while charging and recommend.
