Tested and working fine! NO CLAMPS are included, so you'll need those with this. The 1.5 amp battery charger and maintainer is perfect for charging 6 volt and 12 volt batteries. You can use it to charge the batteries of RVs, motorcycles, lawn mowers, ATVs, boats or jet skis, classic cars and many other vehicles. Great for someone who needs a charge on their battery in a pinch. I'll ship this out within one business day of purchase via USPS Ground Advantage as well. Please feel free to message me with any questions and thanks for looking at this listing.
