More details

More info

BAT-3V6-R20 is a primary lithium‑thionyl chloride (Li‑SOCl2) cell — Saft LSH 20 — in R20/D format. It provides a stable 3.6 V nominal voltage and long shelf life, intended for battery-powered infrared beams and alarm/security equipment.

Key technical data:

  • Nominal voltage: 3.6 V (open circuit ≈ 3.67 V)
  • Nominal capacity: 13.0 Ah (at 15 mA, +20 °C, 2.0 V cutoff)
  • Pulse capability: typically up to 4000 mA (short pulses)
  • Maximum recommended continuous current: 1800 mA
  • Operating temperature range: −60 °C to +85 °C
  • Dimensions: Ø 33.4 mm × 61.6 mm; typical weight ≈ 100 g
  • UL Component Recognition (File No. MH 12609); restricted for transport (Class 9)

The BAT-3V6-R20 is specified for use in JABLOTRON devices such as JA-150IR, JA-151IR and JA-180IR and is suitable where long service life and occasional high-current pulses are required.

Handling and safety: Do not recharge, short-circuit, disassemble or expose to temperatures above 100 °C. Use tabbed or lead‑wired versions for solder-free integration when required. Follow applicable regulations for transport and disposal of primary lithium batteries.
