It charges and maintains batteries from 30 to 350Ah, which makes it well suited to performance vehicles, trucks, boats, and caravans with large or multiple batteries. It supports WET, MF, Ca\/Ca, AGM, EFB, GEL, and LiFePO4 types, charging lead-acid at 14.4\/15.8\/13.6V and lithium at 13.8\/14.4\/13.3V, and it adds desulphation and reconditioning modes to restore tired batteries plus a constant 13.6V supply mode for powering 12V equipment. A built-in temperature sensor adjusts charging to the weather, and the charger is spark-free and reverse-polarity protected with an IP44 rating. CTEK backs it with a 5-year warranty.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: fully automatic 15A charger and maintainer\u003c\/li\u003e\n\u003cli\u003eOutput: 15A; lead-acid 14.4\/15.8\/13.6V, LiFePO4 13.8\/14.4\/13.3V\u003c\/li\u003e\n\u003cli\u003eCharges and maintains 30-350Ah\u003c\/li\u003e\n\u003cli\u003eBattery types: WET, MF, Ca\/Ca, AGM, EFB, GEL, LiFePO4\u003c\/li\u003e\n\u003cli\u003eDesulphation and reconditioning modes\u003c\/li\u003e\n\u003cli\u003eConstant 13.6V supply mode for 12V equipment\u003c\/li\u003e\n\u003cli\u003eTemperature sensor, spark-free, reverse-polarity protected, IP44\u003c\/li\u003e\n\u003cli\u003eWarranty: 5 years\u003c\/li\u003e\n\u003cli\u003ePart number: CTEK40-727\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat batteries does the CTEK NXT 15 charge?\u003c\/h5\u003e\u003cp\u003e12V lead-acid and LiFePO4 lithium batteries from 30 to 350Ah, including WET, MF, Ca\/Ca, AGM, EFB, and GEL types.\u003c\/p\u003e\u003ch5\u003eHow much charge current does it deliver?\u003c\/h5\u003e\u003cp\u003eUp to 15A, which suits larger batteries in trucks, boats, caravans, and performance vehicles.\u003c\/p\u003e\u003ch5\u003eDoes it have a power supply mode?\u003c\/h5\u003e\u003cp\u003eYes.
