This charger was new, but had battery clamps instead of the Anderson cconnectors like the new version. It worked perfectly. It took 5 hours each to charge two new lithium batteries. I was very pleased with its performance. It was also $50 cheaper than the updated (out of stock) version,and on Amazon, $30 cheaper for the same style of charger. So far, I'm pleased with the quality of the Li Time products and delivery.
