I carry an extra sub-C cell for my glo starter in a 35mm film container that I have screwed to the inside edge of the field box. My field charger is a model without the built-in glo charger. Having the extra battery is so much easier than carrying, and hooking up a field charger for the glo starter anyway. Besides.... I can be ready to use it in about 15 seconds.
