Brand new, unused 7 amp hour 12 volt rechargeable sealed battery pack, with fused cigarette holder. Like a mini Kendrick's battery.
Comes with a nice carrying case with strap. Includes a 1.2 amp recharger, which recharges the battery in 7 hours (overnight). Excellent for travelling with. I had bought it for a used telescope I was buying, but the deal fell through. Asking $60 U.S., shipping included.
