The Forney Frontline 5A Smart Battery Charger and Maintainer is a fully automatic 6V and 12V charger built for automotive, marine, powersports, lawn and garden, and equipment storage applications. Compatible with lead-acid (Wet, EFB, MF, Ca, AGM, Gel, and Deep-Cycle) and lithium (LiFePO4) batteries up to 120 Ah, this 5-amp charger automatically adjusts to match your battery's needs with no menus or manual settings required. An LED display provides real-time voltage readout and charging status so you can verify progress at a glance. Force Charge Mode enables charging of deeply discharged batteries that fall below the standard detection threshold, helping recover stored or neglected batteries. Automatic float mode maintains a full charge without supervision once charging is complete. Built-in protection against reverse polarity, sparks, short circuits, overheating, and overcharge keeps users and equipment safe. A stowable hanging hook supports under-hood, fender, or shop mounting for cleaner cable management. The IP65-rated housing resists water, oil, UV, chemicals, and abrasion. Includes quick-connect clamps and ring terminals (M10). Certified to ETL (UL1236 and CSA C22.2 No. 107.2), FCC, and DOE standards, and backed by a 3-Year Limited Warranty.
