Remote (as opposed to local or inside the charger) temperature compensation is well worth the added expense, as is remote voltage sensing. Both features enable a charger to more effectively tailor its charge profile to the battery bank’s needs. Cool batteries can accept more current, and recharge more quickly than hot batteries; however, if the charger can’t determine the temperature, it can’t adjust its output accordingly. Also, the voltage at the batteries may be different from the voltage the charger is sensing at its output, making remote voltage sensing desirable. Once again, it allows a charger to more accurately adjust its output to suit the batteries’ state of charge.
