     First check whether the battery is really damaged. Unplug the AC power, then press the laptop power button, see the battery light is flashing, if the flash, laptop battery under normal circumstances should be no problem. With a multimeter Measure the battery voltage, if the voltage is 11 volts, the dell xps m1530 battery  charge and discharge due to the long wrong can not be discharged.
     And is fully discharged. Remove the battery from the notebook, and then find a large resistor (you can also use routers, hubs, switches and the like), a full discharge, because I did not find major resistance, so to find a useless router discharge, the results were quite good, the router lights to show whether the above discharge fully, with the wires connecting the battery and the router, the router if the connection is correct light will light up, if you do not look down the right line on it. Even after completing the discharge is to wait for completion of voltage with a multimeter is best to look at the amount of a few tenths. Then install the HP Compaq Business Notebook 8510p battery to the laptop, for 8 hours of charging, red end power, unplug the AC power, so laptop own discharge, until the automatic shut down and then it just means full discharge, so that more than 3 consecutive full discharge your battery is basically back to the performance of the factory.
     These are my own repair cells that experience, I hope useful.
