Nickel cadmium battery deep cycler device

A device for draining a battery prior to recharging the battery, the device comprising:

• means in the form of first and second input terminals for connecting the device to a battery to be discharged;
• means in the form of a first circuit coupled to the input terminals for draining current from the battery connected to the input terminals, the first circuit having sufficient resistance to drain current from the battery without damage to the battery when the battery has an output voltage above a predetermined threshold level;
• means in the form of a second circuit coupled to the input terminals for draining current from the battery when the battery has an output voltage no greater than the threshold level;
• and
• means in the form of a relay coupled to the input terminals for decoupling the second circuit from at least one of the first and second input terminals when the battery has an output voltage greater than the threshold level;
• wherein the threshold voltage is approximately 3.3 volts.
