have my battery cable in a larger cardboard box . I get this to dispense with the box and increase my cargo space for other necessity of life . this reduce the footprint by 2 fold . initially I wasnt sure if they would fit into this bag and be wish I have get the larger one -lrb- i have bulky 20 foot cable -rrb- . after a couple of re-roll I be able to get they in quite nicely . very satisfy with this item .
