Battery Powered Trimmer

Is this a Ni-Cad or Ni-Mh. If Ni-MH ... he does not need to completely empty. Be careful when draining a battery ..... using a direct short can cause a fire or very little damage the battery. Hanging a light bulb Volts DC for the battery connections to empty safely ... it may take a little unusual rigging to keep the power goes bulb.

Take a zip tie and tie the trigger and let set until all the juice. Or take it. It will be dead.
