Most of the new DeWalt use lithium ion batteries or lithium-ion cells, because they produce a higher voltage for less than cells are the tool necessary to power so that the battery very much easier. Former nickel-cadmium battery DeWalt contained packages or NiCad cells, which, in time not to hold their charge so that the tool of the power to find quickly died is, even if you it be simply loaded. However it is not necessary, NiCd batteries(e.g. DEWALT DC9071 battery, DEWALT DC9091 battery) can quickly and cost-effectively to renovate your old DeWalt battery .
Put the old DeWalt battery, which should to be renovated on a desktop. Read the label on the bottom or on the side of the battery, to determine the output voltage. The most ancient DeWalt NiCd rechargeable batteries are either 12 volts(DeWalt DE9074 battery) or 14.4 volts(DeWalt DE9094 battery).
You share the voltage on the former DeWalt battery with 1, 2-output displayed. This shows the number of replacement cells, you have to buy each cell NiCd 1.2 Volt produces. For example, DeWalt 14.4 volt battery of 12-cell has only 14.4 Kbps to 1.2 subdivided is equal to 12.
Get the number of replacement cells, you need to renovate the old DeWalt battery from a supplier of electricity, so if the battery 14.4 volt get 12 or, if his 12 volts 10. NiCad cells available anywhere and relatively inexpensive.
You use a small Phillips screwdriver, loosen the six screws, that the battery in position to keep lid. Repealed, if the lid is raised and you will find within individual cells.
Find out how the cells in the DEWALT battery are set. Cells, sometimes in click, others have tabs welded. If they click, tear off with a screwdriver to. If they are merged, you need a soldering iron to heat. On the tab and the battery, put the tip of soldering iron. Let the solder to melt. Pry of the cell of the Chamber of the batteries as soon as the solder melts, and then remove the iron. Repeat the procedure to remove all cells until you. Turn the iron.
Put 10 or 12 NiCad cells in a clear plastic bag and put aside. Nickel-cadmium battery recycling facility they need to use the batteries, they should be thrown in your normal household waste. You can advice on how to remove the battery, by clicking the link in the resources section.
Set the NiCad replacement cells in the empty battery. Please add it properly at the terminals of the cell with the right connections in the battery adapted. "-" On the other, each cell is "+" on one end and marks. The pulled a small piece of metal at the top of the cell is the positive pole and the surface flat on the floor of the cell is the negative terminal. Look in the battery, and you will see a chart like the cells must be equipped with. "-" It's "+" for the positive and marked for the negative. Get it wrong, the cells damage and is not dangerous, but the battery does not work.
If you use this method, or the heat of a soldering iron, when they sealed shall be adapted to, press the cells in place with your fingers. Touch the end of iron welding in the leg and battery. Can make some welds and melt. Remove iron solder and solder paste when it melts. Let harden welding and repeat the process on the other tabs. Turn the weld if all cells in the village are welded.
Put the lid on the battery. Put six Phillips screws in the holes and pull the screws with a Phillips screwdriver. Set your DeWalt renovated battery into the unit, which supplies it.
