Steps:1.- Low Volt Start (0.5V)2.- TEST before charge3.- Temperature check4.- Ultra LOW VOLT SAVE5. - LOW VOLT SAVE / cellmonitoring6.- TEST - cell damage7.- Cell-balancing CHARGE8.- OPTIMIZE9.- TEST after CHARGE10.- OptiMate Maintenance Special features:• Battery SAVE mode with BMS reset : starts from 0.5V with continuous monitoring / testing of charge acceptance or bad / shorted cell condition. Unnecessary (and unsafe) charging of a bad battery is prevented. • safety :Automatic charge rate adjustment to ambient temperature sensed at the charger. Reduced charging below freezing, no charging if temperature is below -20C/-4F (can damage lithium batteries).• Ampmatic : Microprocessor adjusts current to ideal LiFePO4 charge curve to match battery size / condition, for fastest and most complete charge. SAFE: No risk of overcharging. Totally safe for vehicle electronics. Sparks suppressed. Safe for long-term battery maintenance. Automatic shut-down if short-circuited or battery disconnected. 3-year limited replacement warranty.
