How To Rebuild A Power Tool Battery-super bass

.puters-and-Technology Make sure that you purchase the same type of rechargeable battery cells unless you are sure that your charger and tool will operate with the other type. If so, use Ni-Mh batteries — they are superior to Ni-Cad cells in that they do not develop a "memory" when charged to less than full capacity. Use a rotary tool with a wire brush attachment to clean off any oxidation on the contacts and connecting wires left in the pack. Refer to your notes and install the new batteries the same way as the previous arrangement. Solder the new connections securely. Attach a chisel tip to the soldering iron, and heat it up. Use the tip to cut an outline along the top of the base of the battery pack. Pull off the top and set it aside. Inside will be a group of C-size rechargeable batteries in a generic cardboard casing. Read the text on them, which will indicate whether the cells are Nickel-Cadmium (Ni-Cad) or Nickel Metal-Hydride (Ni-Mh). Put the top of the battery case back on and fasten the screws, or for the molded pack that has been cut open, use a liberal amount of an epoxy adhesive to glue the pieces back together. Be sure to let the pack charge fully (overnight) before using it for the first time. Eg : 1.DeWalt has established itself as a maker of quality and long-lasting cordless tools. These tools often be.e favorites of their owners and get put to heavy use. While the tool itself is likely to last for many years, the battery packs that power these tools generally have a shorter effective life. If you have noticed your DeWalt battery pack has less power and does not charge well, you can rebuild it and have your favorite tool performing like new again. Check the plastic case of the battery pack for small screws that allow access to the inside of the pack. If there are screws present, remove them with the screwdriver and open up the pack. Look over the grouping of sub-C rechargeable battery cells inside the pack and write down how they are arranged and connected. You will use these notes to reassemble the pack with new cells later. Warm the connections for each cell with the soldering iron, and remove the old cells. Place the top piece of the plastic case back over the cells and align it with the bottom piece of plastic. Insert the screws and secure them firmly. If the pack had no screws and was cut open, mix some epoxy adhesive and glue the two pieces together. Place the new pack on the charger overnight and it will be ready to use in the morning. 2. The batteries on cordless power tools are usually the first part to fail. If you’ve ever priced a replacement battery pack, you’ll know that it is probably not a cost-effective purchase. Most people would rather buy a new tool than spend over half the price of a new tool on a replacement battery pack. The best option might be to rebuild the batteries, but only if you have some experience using a soldering iron. Remove the battery pack from your cordless tool. Unscrew the screws holding the battery case together. Open the battery case. Remove the battery cells–they will all be wired together as a unit. Remove the connecting wires by holding them with pliers while melting the solder that holds the wire to the battery terminals, using a soldering iron. Slide the battery cells into one half of the battery case. Replace the other half of the cover. Fasten the screws that hold the case together, using a screwdriver. Charge the battery pack overnight before using it with your cordless power tool. About the Author: 相关的主题文章:
