Description:
SAFT LS17500 Size A 3.6V 3600mAh Primary Lithium Thionyl Chloride (Li-SOCl2) Battery.
SAFT LS17500 Battery is a primary lithium A cell.
The Saft LS17500 has concentric electrodes also called "bobbin? construction that enables maximum loading of active materials and corresponding energy.
The Saft LS17500 cell is designed specifically for long-term (3 to 15 years) applications, featuring a few UA based currents and periodic pulses, typically in the 5-150 mA range.
Lithium Thionyl Chloride has the highest energy density of any practical Lithium battery chemistry, three times greater than Alkaline (Zinc Manganese Dioxide) batteries.
It also has the widest operating temperature range of -55℃ to + 85℃.
Self discharge is low at less than 1% per annum at 20℃, giving an effective shelf life of 10 years.
This A Size Lithium Thionyl Chloride battery is commonly used in wireless alarm systems, memory backup for computers, high tech dive computers, MP3 players, bar-code scanners and night vision equipment.
