They are highly recommended for use on the primary charging source where the battery bank may experience moderate to extreme temperature variations . This is especially important to correct battery charging if the battery bank temperature is expected to vary by about ten degrees F or more. Can save time and money, on battery maintenance and replacements. Less need to make seasonal charge adjustments to keep battery hydrometer readings in the correct range. Can and often will, improve battery life & battery performance! Phone style RJ12 plug, only the two center pins are used. Only 2 wires are "necessary" and no polarity. This temperature sensor uses a thermistor as a thermal transducer. Cable length from RJ12 plug to thermistor sensor is 15 ft.
