Tadiran TL-5955/T 3.6V 2/3 AA 1.5 Ah Lithium Battery with Tabs

SKU CH-MKW0-MQ6X4

3.6 V lithium thionyl chloride cell in 2/3 AA size with 1.5 Ah capacity and spot-welded tabs for direct PCB mounting

  • 6 V stable voltage powers devices reliably
  • 5 Ah capacity extends runtime between replacements
  • 60 °C to +85 °C range suits harsh environments
  • Less than 1 % self-discharge retains charge over 10-year shelf life
  • Spot-welded tabs simplify secure PCB mounting

Tadiran TL-5955/T 3.6V 1.5 Ah Lithium Thionyl

This primary lithium battery uses a 2/3 AA form factor with spot-welded tabs for direct PCB mounting. It delivers a nominal 3.6 V and 1.5 Ah capacity for long-life, low-drain applications such as utility metering, alarm systems and industrial sensors. The non-rechargeable chemistry suits designs that require years of unattended operation.

Sustained Load Behaviour

The cell supports a maximum continuous current of 75 mA and can supply pulse currents up to 150 mA. Voltage remains stable across most of the discharge life and the operating range spans -60 °C to +85 °C. Self-discharge is below 1 % per year at +20 °C, so capacity is largely retained during extended storage or standby periods.

Installation Notes

Solder only to the pre-welded tabs; never apply heat directly to the can. Observe correct polarity and avoid mixing this model with other battery types in series. The inorganic electrolyte is corrosive if the seal is breached, so handle carefully and store in a clean, cool, dry, ventilated area not exceeding +30 °C.

Questions about this item

Does the 3.6 V lithium thionyl chloride cell generate noticeable heat or draw power when it runs continuously in a meter for days?

The chemistry delivers a stable 3.6 V with a maximum continuous current of 75 mA and pulse capability of 150 mA, so self-heating remains minimal during long-term low-drain operation.

What must my device already provide for the spot-welded tabs on this 14.5 mm diameter battery to make a reliable connection?

The PCB or holder needs through-hole pads or spring contacts spaced for the 33.5 mm height and 0.57 in diameter so the pre-attached tabs can be soldered or pressed directly without extra wiring.

Will this ER14335-size cell work alongside the older TL-2155 and TL-5155 packs I already have in the same equipment?

Yes — the TL-5955/T shares the 2/3 AA form factor and 3.6 V nominal voltage with the TL-2155, TL-5155 and Xeno XL-055F, allowing direct substitution in existing battery compartments.
