(10) 3.6 Volt 1/2 AA Omni Lithium Wireless Adt Alarm Batteries
The LS 14250 has a "bobbin" construction based on the Lithium-Thionyl chloride (Li-SOCl2) chemistry. This range perfectly suits high energy and high voltage requirements in a wide range of temperature.  The concentric electrodes enable the maximum loading of active materials and correspondingly, maximum energy and lowest self-discharge.  This range is designed specifically for long-term (5 to more than 20 years) applications, featuring a few A base currents and periodic pulses, typically in the 5-150 mA range.
