【Dual Voltage Lithium-Ion Battery Compatibility】Works with all 12V and 18V lithium-ion batteries (matching system), including popular models like 48-11-2401, 48-11-2440, 48-11-2460, 48-11-1815, 48-11-1850, 48-11-1860 and 48-11-1890. No need for multiple chargers—super convenient for daily use and job sites.
【Smart Sequential Charging】It’s a single-port smart sequential charger—charge the first battery fully, then it auto-switches to the second (if you plug it in). IMPORTANT NOTE: You can’t charge multiple batteries at once, only one at a time, so it charges steadily and efficiently.
【3.0A Efficient Charging Output】It has a 3.0A high-efficiency, high-speed output—charges much faster than standard chargers, getting your batteries ready quickly to avoid work delays.
【LED Charging Indicators】Built-in easy-to-use LED indicators show you everything clearly—steady red means it’s charging, steady green means fully charged. If it blinks red (battery too cold/hot), just let the battery return to room temperature and try again. Check at a glance, no hassle.
【Smart Safety Protection】It has smart overcharge, thermal protection and advanced circuit protection, monitoring voltage, current and temperature to stop overcharging, overheating and short circuits. We offer a 1-year warranty and 24-hour customer service—feel free to contact us anytime with questions.
