IMPRES batteries, when used with an IMPRES charger, provide automatic, adaptive reconditioning, end-of-life display, and other advanced features. Data is stored in the battery and communicated to the charger via a unique IMPRES communication protocol, which is designed to maximize talk time and optimize battery cycle life. This 3000 mAh, low-voltage battery provides 25+ hours of talk time when used with compatible MOTOTRBO Enhanced Series Radios. The IP68 rating means it can be fully submersed at two meters for two hours.
