impres Li-ion, 2000 mAh, 7.5V Battery
IMPRES HNN4003 SMART LI ION BATTERY
impres™ 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.
