3.6V non-rechargeable lithium battery, with terminals for direct mounting on a circuit board. Non-rechargeable 3.6V lithium batteries are typically lithium thionyl chloride (Li-SOCl2) cells, a primary chemistry offering stable voltage, very low self-discharge and long service life even under light loads: for this reason they are used as backup power for electronic control boards and industrial equipment.

• Voltage: 3.6V
• Type: non-rechargeable
• Terminals: with terminals for soldering/board mounting
• Part code: AGWSELE1960

Replace it when the voltage drops below the operating threshold of the board it powers, causing memory loss, low-battery alarms, or malfunctions of the electronic control unit.
