Sears offers the DieHard Platinum 6-volt / 12-volt Battery Charger and Maintainer, model no. 71219, for $19.99. Choose in-store pickup to dodge the $6.50 shipping charge. That's tied with last month's mention and the lowest price we could find by $11. It features a 2-amp charge, float-mode monitoring, auto voltage detection, and reverse hook-up protection. Deal ends September 13.
