DUSLAN 3.6V 1/2 AA 1200mAh Lithium Battery with Tabs

SKU CH-MZ9J-X3NRA

A 3.6V 1/2 AA lithium-thionyl chloride cell with 1200 mAh capacity and spot-welded tabs for direct PCB mounting

  • Battery type1/2 AA Lithium
  • Reliable 1200 mAh capacity for long backup power
  • Wide -55C to +85C operating range suits harsh environments
  • Spot-welded tabs enable secure direct board mounting
  • Compact 14.5 mm x 25.25 mm size fits tight spaces
  • 6 V lithium-thionyl chloride chemistry delivers stable voltage

Purpose and fit

This primary lithium-thionyl chloride cell delivers 3.6 volts and 1200 mAh in a 1/2 AA form factor with spot-welded tabs. It suits engineers and technicians who need reliable backup power for circuit boards, meters, medical devices or remote telemetry units.

Replaces and when to upgrade

The cell replaces legacy LS14250, ER14250, TL-5902, TL-2150 and similar references used in legacy boards. The jump is worth it when existing packs show voltage sag below 3.6 volts or when a fresh 10-year shelf life is required for spare inventory.

Interface and practical limits

The battery is not rechargeable and must never be placed in a charging circuit. Operation spans -55 to +85 Celsius, while storage should stay at or below +30 Celsius in a clean, dry, ventilated area. Soldering directly to the tabs risks damage; use a proper holder or spot-welded connection.

Questions about this item

Will the 14.5 mm diameter and 25.25 mm height fit my device's battery compartment?

The cell measures 14.5 mm in diameter and 25.25 mm in height; verify those dimensions against your compartment before ordering.

How do I solder the spot-welded tabs without damaging the lithium-thionyl chloride chemistry?

Use a temperature-controlled iron at the lowest effective heat, apply flux, and solder each tab for under three seconds to avoid overheating the 3.6 V cell.

When should I replace the 1200 mAh cell in a meter that draws 1 mA continuously?

At a 1 mA load the nominal 1200 mAh capacity yields roughly 1200 hours; plan replacement before voltage drops below your device's minimum threshold.
