The 3B6880 or 3B880 Wafer Cell has three PCB pins that protrude 8 to 9 mm. The central pin is the positive terminal, the two outer pins are the negative terminals.
This 3B6880 or 3B880 Wafer Cell is widely used for CMOS memory backup in personal computers, and for many other electronics applications. Also used in SRM Pro, SRM Amateur, and some older SRM Dura Ace cycle power meters.
This 3B6880 or 3B880 is a high-capacity cylindrical-type Primary Lithium Battery with a bobbin structure and laser-sealing. The 3B6880 or 3B880 uses Lithium Thionyl Chloride chemistry for a high energy density and a wide operating temperature range of -40°C to + 85°C. Self discharge is low at less than 1% per annum at 20°C, giving an effective shelf life of 10 years.
