With 15 amps of charging power, the NXT 15 is designed for larger batteries and faster charging than typical 5A maintenance chargers. It is an excellent option when you need to recharge a vehicle battery efficiently while still having the ability to leave the charger connected for ongoing maintenance.
The NXT 15 supports a wide range of 12V battery technologies, including:
The dedicated lithium program provides charging specifically suited to compatible LiFePO₄ batteries.
The NXT 15 includes a dedicated RECOND function designed to help restore deeply discharged compatible lead-acid batteries. This function is particularly useful for batteries that have experienced extended periods of low charge.
SUPPLY mode transforms the NXT 15 into a regulated 13.6V/15A power source. This can help maintain vehicle electrical power during certain service procedures where a stable external power supply is beneficial.
The integrated temperature sensor automatically adjusts charging to compensate for temperature variations. This helps optimize battery charging performance in changing environmental conditions.
The NXT 15 is designed for simple connect-and-forget operation. Its automatic charging cycle, spark-free connection, reverse-polarity protection, and low back-current drain help make long-term battery maintenance convenient and safe.
