Be extra cautious to reduce risk of dropping a metal tool onto battery.Do not place the charger on the battery while charging.Do not charge non-rechargeable batteries.Do not charge a frozen or damaged battery.Rinse immediately with water if acid comes into contact with skin or eyes. Do not expose charger to the sun, or under high temperature environment.Provide ventilation to prevent flames and sparks. Explosive gases may emitting from battery during charging.Check battery manufacturer specifications before using.The FBC122412D charger is designed for 12V and 24V Lead-Acid, LiFePO4 batteries with capacity from 6AH – 200AH(12V), 6AH – 100Ah(24V).Auto-stop when fully charged, auto-awake and pulse compensate after voltage drops allow a long-time connection, with charging fuller and battery more durable. 【Restore and Maintain Your Batteries】 The smart battery charger auto-detects and repairs severely-sulfated battery terminals (15.8V), and recondition battery (15.8V) to rehabilitate the lost performance.The car battery charger, +0.2v on the basis of the original charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations. 【Superior Engine Start and Winter Mode】 Engine start aid feature helps in activating your car battery with insufficient power to emergently start your vehicle in 100 seconds.Fully-automatic features, manual selections, and prior-setting memory function make charging automotive battery more convenient and high-efficient. 【Voltage-Drained Battery Savior】 TowerTop battery charger, up to 84% more efficiency, detects and charges batteries as low as 1 volt, ideal for dead or idle 12v lead-acid batteries including STD, GEL, AGM, and DEEP CYCLE.➤NOTE: It can not activate a dead battery or repair a battery which is damaged seriously it also can not repair a battery back to 100% new. 【PULSE REPAIR FUNCTION】Intelligent control system, strong pulse repair technology, remove vulcanization, repair slightly damaged batteries, reduce water loss, Provides stronger engine starts and extended battery life.【HIGHLY COMPATIBLE】Suitable for both 12V and 24V batteries, making it easier to use.It works with Calcium, AGM, EFB, MF, FLOODED, VRLA, SLA and Wet batteries, meaning that it can be used for the batteries in Car, Truck, Motorcycle, RV, SUV, ATV, golf cart, tricycles, agricultural vehicles, bus, etc.Automatic detection of ambient temperature, so that winter can be full speed, summer is not overload.optimized for any climate, easy to deal with a variety of harsh voltage environments. 【THE LATEST INTELLIGENT CPU CONTROL】Portable battery charger/maintainer automatically adjusts the charge current and maintainability according to the temperature.Most will charge then maintain six- and 12-volt batteries and alert the owner to crossed positive and negative cables. Prices range from under $30 to more than $100. Where there was once a simple green light to let you know a battery was charged, now there are multiple sensors and functions, plus LED monitors. Plug it in and forget it for a day, a week, or the entire season. The modern maintainers will turn on and off to avoid overcharging. Traditional battery trickle chargers can only supply a constant charge. Nothing kills a car battery quicker than when a car sits for weeks and months on end. These units have always been popular with car collectors, whose dirty little secret is that they don’t drive their automotive gems all that often-and especially not in the winter. New trickle chargers can detect weak batteries, alert the operator to dangerous crossed battery cables and keep the battery ready to go through months of inaction. The humble battery trickle charger has evolved to a smart, microprocessor-controlled battery charger-maintainer.
