Lithium TCL primary batteries optimised to give long life and to support real time clock and RAM functions of AT or compatible computers with 6V & 3.6/7V systems. The batteries contain internal resistors and anti-charge diodes.
This battery is non rechargeable

Not Rechargeable

Lithium Non –rechargeable Batteries
Lithium Thionyl Chloride technology offers very high energy density, high terminal voltage, level voltage discharge and very long shelf life
10 year storage capability
Very low self discharge (1% or less per year) at 20ﾟC

All cells are hermetically sealed in stainless steel cans (low magnetic signature & superior resistance to atmospheric corrosion)
For series or parallel connections of more than one cell refer to the data sheet – do not solder directly to the cell – used tabbed versions instead.
Operating temperature -60 ﾟC to +85 ﾟC

Underwriters Laboratories (UL) component recognition
