LONG-LASTING POWER & SAFETY : The NYI DSC IMPASSA 9057 Battery is temperature-sensitive, double short-circuit-proof and PTC-protected and has been thoroughly tested on professional equipment, a process that guarantees the long life and consistently high characteristics of our batteries so you can buy with confidence.
Higher battery life: The replacement battery for ADT branded DSC alarm panels has a larger capacity than other brands and is ideal for your requirements.
PLEASE FULLY CHARGE BEFORE USE : Batteries are initially low for shipping safety, remember that new battery packs must be fully charged before use. It may take about 2 days.
NOTE : Before replacing the ADT control panel battery pack, please unplug the wall outlet. This completely de-energizes the ADT alarm system and clears any old fault codes. After the battery pack is installed, plug the power cord back in.
