Home mechanics who have been around the block know that every well-equipped garage needs a powerful wheeled battery charger and jump starter to help keep their vehicles running smoothly. Some mechanics like the convenience of fully automatic battery chargers, but others prefer to take charge and employ a manual charger. For those mechanics who prefer complete control, the CRAFTSMAN CMXCESM233 250A 6V/12V Wheeled Battery Charger and Jump Starter is an ideal choice. The CMXCESM233 from CRAFTSMAN is designed to meet the brand's high standards and features a 135-minute timer that controls every part of the charging process as well as providing users with multiple charging options. This CRAFTSMAN unit delivers a 250 cranking amp (12V) engine start, which is powerful enough to start large engines, including those found in SUVs, trucks, RVs, and cars. The CMXCESM233 also has two boost modes—50A 12V and 25A 6V/12V—that will rapidly add charge to batteries, even those that have been completely depleted. The unit also has a 10A 12V charge mode for routine battery charging. Designed to safely charge 6V and 12V standard, AGM, gel, and deep-cycle batteries, the CMXCESM233 also features rugged construction to withstand tough conditions and ensure years of reliable operation. Additional features include solid wheels, a retractable handle, 6-gauge output cables, and color-coded clamps.
