Motorola WPLN4187 [replaced by PMPN4285A]

Motorola WPLN4187 IMPRES smart energy system ensures maximum talk-time and optimized battery cycle life through the use of its advanced charging algorithm and automatic reconditioning features. The smart energy system reconditions IMPRES batteries when they need it automatically, keeping them in peak condition. Its advanced conditioning features allow batteries to be safely left on the charger for extended periods of time without incurring the damaging heat build-up which can rob batteries of cycle life. In addition, batteries left on the charger are kept fully charged so they are always ready when you need them.

The IMPRES system reconditions batteries when they need it based on their usage pattern. Talk time and cycle life are optimized and the need for manual maintenance programs reduced or eliminated. This rapid rate, tri-chemistry charging system will also charge existing legacy batteries and supports multiple radio platforms.
