My Bushnell has a "6V" port to accept external power. I assume this means I need a 6V rechargeable battery and 6V solar charger.

I know this question may be specific to Bushnell but how do I attach the battery to the "port?" In other words, where do I get a connecting wire from the battery that fits the port?
