This ensures that energy is reliably available even after many years. Features  ModelTadiran SL-760/PR TechnologyLithium thionyl chloride (Li-SOCl₂) SizeAA (Mignon) Rated voltage (V)3.6 Capacity (mAh)2200 Max. continuous discharge current100 mA Self-dischargeapprox. 1% per year Operating temperature (°C)-55 ~ +85 Dimensions (Ø x L, mm)approx. 14.7 x 50.5 Weight (g)approx. 18 ConnectionRadial pins (PR) RechargeableNo  FAQs about this Tadiran batteryWhat does the connection with "radial pins" mean?In contrast to axial connections, which exit from the centre of the terminals, radial pins are arranged so that they exit from one face of the battery. This configuration is optimised for specific layouts on printed circuit boards (PCBs) and enables particularly stable and defined mounting of the cell.What is the advantage of the SL-700 series over other series?The SL-700 series is optimised for the absolute lowest self-discharge. It is the best choice for applications that require very little power over many years, such as memory backup in computers. In contrast, other series (such as the SL-300 iXtra) are designed for applications with higher pulse current demand.For which devices is this battery type suitable?This battery type is ideal for professional electronics in which the battery is permanently soldered and an extremely long service life is decisive. Typical applications are meters, industrial computers, alarm systems and long-life sensors with specific PCB layouts.Is this battery rechargeable?No, this is a primary lithium battery and must not be recharged under any circumstances. Attempting to charge the cell is dangerous and can lead to overheating, leakage or rupture of the cell.What does the passivation effect mean for this battery?After longer storage, a protective layer forms on the lithium surface. This layer is the reason for the extremely low self-discharge. On first use, it can lead to a short voltage delay. This should be considered in circuit design for applications that require current immediately after activation.
