Brand new, unused 7 amp hour rechargeable sealed battery pack, with fused cigarette holder. Like a mini Kendrick's battery.In fact the company that sold it to me (VR Products) was at one time making batteries for Kendrick's.
Comes with 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. Weighs about 5 lbs. Asking $70 U.S., shipping included.
