impres^TM smart chargers help maximize battery operating time between charge cycles - virtually eliminating memory effect in nickel-based chemistries - by automatically customizing operation to the user's unique charging habits. Special patented circuitry assesses the battery condition and charges it ... reconditions it if necessary ... keeps it fully charged over time while controlling heat build-up ... and even notifies you if the battery is beyond its useful life. You can charge and recondition batteries individually, or while still attached to the radio.
