Xantrex Freedom 458 Battery Temperature Sensor

For a Freedom 458 inverter/charger that uses a battery temperature sensor, this Xantrex replacement restores the charger’s ability to read temperature at the battery. The sensor can be positioned at a battery terminal post or against the battery case. By monitoring the battery rather than the air around the charger, it supplies information used for temperature-compensated charging. It is intended for the Freedom 458 series, not every Xantrex charger.

A 15-foot attached communication cable provides reach between the battery bank and the compatible inverter/charger. The cable allows the sensor to remain at the battery while the charging equipment is installed elsewhere in the boat or vehicle. The charger uses the reported temperature when adjusting charging voltage to suit battery conditions.

• Replacement sensor for Freedom 458 inverter/chargers
• Attached 15-foot communication cable
• Can mount at a battery post or battery side
• Supports temperature-compensated charging

This is useful when replacing a damaged or missing sensor during service on a Freedom 458 installation. Make sure the existing charger has the correct sensor connection before ordering. Route the cable and install the sensor in accordance with the inverter/charger instructions so it can measure the battery temperature reliably. Browse more battery charging accessories at CritPro.
