DESCRIPTION

Keep car, motorcycle, boat, and seasonal-equipment batteries ready with this 40A smart charger. It supports 12V and 24V lead-acid batteries, plus 12V LiFePO₄ charging. Once connected, it detects battery voltage automatically and lets you select a charging current suited to the battery.

Six-stage charging and maintenance

The charging sequence moves through low-current start, pre-charge, constant-current, constant-voltage, float maintenance, and power disconnect. After charging, the unit monitors battery condition and resumes at the appropriate point when needed. A long press of Current Selection can bypass pre-charge for fast charging.

Battery care and compatibility

Charging, trickle maintenance, desulfation, and reconditioning functions support AGM, standard, GEL, and SLA lead-acid batteries. Reconditioning mode is intended for 12V lead-acid batteries only. Do not use this charger with 24V LiFePO₄ or other 24V lithium batteries.

Adjustable output and display

For 12V batteries, selectable current settings are 10A, 20A, and 40A. Current selection also adjusts for 24V batteries. The screen shows real-time voltage, current, battery capacity, and charging mode.

    Perfect for work vehicles

    I use this every day in my work truck. It charges a battery for a backpack sprayer and a locator and I have had zero issues. Charges fast and it doesn’t buzz while running.

    Auch für induktive Lasten wie Staubsauger und Kühlschrank, Eismaschine geeignet

    Die ersten beiden Wechselrichter hier gaben trotz 500 W Angabe auf, wenn der Kompressor meiner Minieismaschine starten wollte. Im Betrieb zieht er nur 90 W. Erst dieser hier mit reinem Sinus schaffte das.

    works great

    It looked extremely small and cheesy, I thought it was broke. I am use to hearing the fan on my old one, but there was zero noise on this and I was actually surprised the speed of charge on my cell phone. The other one I also used my fast charger, but this one seems to be faster
