1. A battery connector comprising:
power terminals configured to be coupled to a load having an input capacitance;
power pins directly coupled to the power terminals such that no intervening circuits are interposed between the power pins and the power terminals;
a charge pin, the charge pin being longer than each of the power pins; and
an antispark circuit electrically interposed between the charge pin and the power terminals, the antispark circuit comprising:
a dissipation circuit configured to charge the input capacitance of the load in response to a battery being coupled to the charge pin; and
a delay circuit configured to delay charging of the input capacitance of the load for a predetermined duration after the battery is coupled to the charge pin.
