Through the use of advanced charging algorithms and automatic reconditioning features, the Impres smart energy system ensures maximum talk-time and optimized battery cycle life. This smart energy system automatically reconditions Impres batteries based on actual usage, keeping them in peak condition. Talk time and cycle life are optimized and the need for manual maintenance programs is eliminated. Its advanced conditioning features allow batteries to be safely left on the charger for extended periods of time without incurring damaging heat build-up which can decrease battery cycle life. In addition, batteries left in the charger are kept fully charged so they are always ready when needed. This rapid rate, tri-chemistry charging system will also charge compatible non-Impres batteries.
