How To Repair Power Tool Battery -meyou

.puters-and-Technology However, nickel-based batteries are still widely used, and although producers have eliminated some of the earlier problems with nickel batteries, can they still lose their ability to keep a full charge after a certain time. Fortunately, in contrast to lithium batteries can usually to repair, by known you a technique, such as a deep discharge. Cordless power tools are a great convenience for both the professional and the do-it-yourself homeowner. Unfortunately, the rechargeable battery packs that power these tools usually fail within 18 to 24 months. What many tool owners do not know is that within these BOSCH 2 607 335 246 battery packs is a simple arrangement of rechargeable size C batteries, which they can rebuild themselves. Power tool batteries that are rechargeable can develop a memory if they aren’t used often or used to their full charge. Once a battery develops memory it can seem to be fully charged but when you use the tool, the battery will be dead within a few minutes. This is an annoying feature of rechargable power tool batteries that you can fix in just a few days with a couple of simple steps. Take the battery from the charger. Put the battery in the power tool. Choose a low-power setting, if it has one. A slow discharge is usually better than a fast discharge, because the battery starts to repair itself, so the longer it will take during the proceedings are the better the results to be likely. Turn the tool again, after it has cooled. You may have thought the battery was .pletely dead, but it is easily recovered only neither works nor have tool. To run it, as before, it is not enough energy to use for all jobs, but it will be for a few minutes or so to run. Turn off the tool and allow 5 minutes for him see whether wins the battery no energy, then on again. If it works, it runs until it stops. If the device does not work, the battery is fully discharged. Turn off the charger to the LED, the color changes or shuts off. Take the Dewalt DE9037 battery from the charger and put in it your tool, which is now ready for use. 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). 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. 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. Run the tool with the battery in the morning. If it will run the tool, use it until it goes .pletely dead. By doing this, you are essentially erasing the memory in the battery and deleting the false empty cycle of the battery. Use a digital multimeter, or DMM, to measure the battery voltage. Turn on the DMM, and set it to measure the rated voltage of the battery. Place the red lead on the positive PANASONIC EY9230 battery pole and the black lead on the negative pole. Read the meter and record the value. If the display shows a number that is at least half of the battery’s rated voltage, the positive lead is on the negative battery pole. If the display reads a negative value of one or two volts, your DMM leads are correctly oriented, but the battery polarity has reversed. Keep track of which pole is which.
