SAFT LS26500 3.6 V 7.7 Ah C lithium battery 6 pack

SKU CH-3Y05-54HS7

Six-pack of 3.6 V 7.7 Ah C-size lithium thionyl chloride cells with 10-plus-year shelf life and -60 °C to +85 °C operating range

  • Battery type26500
  • High operating voltage stable at 3.6 V throughout most of the application lifetime
  • Some of the highest nominal capacities on the market at 7.7 Ah per cell
  • Excellent reliability over extended operating life with low self-discharge under 3 % per year
  • Wide operating temperature range from -60 °C to +85 °C for harsh environments
  • Non-flammable inorganic electrolyte and low magnetic signature for safe deployment

6-pack 3.6 V 7.7 Ah C lithium thionyl chloride cells

This six-pack supplies Saft LS26500 primary cells rated at 3.6 volts and 7.7 ampere-hours each. The C-size format fits equipment designed for that diameter. They are intended for professional devices needing long-life primary power.

Operating range -60 °C to +85 °C

The chemistry operates from -60 °C to +85 °C and holds a low self-discharge rate below three percent per year at +20 °C. Maximum recommended continuous current is 150 mA with pulse capability up to 300 mA. Voltage stays stable through most of the service life.

Button-top termination non-rechargeable 10-year

Each cell uses a button-top termination and weighs 48 grams. The electrolyte is non-flammable and non-pressurised at ambient temperature. Cells are not rechargeable and must not be soldered directly. Store in a clean, cool, dry, ventilated area not exceeding +30 °C.

Questions about this item

How do I install the button-top LS26500 into a C-size holder and what step do people get wrong?

Insert the 26 mm diameter cell with the button top facing the positive contact; the common error is forcing a flat-top cell or reversing polarity, which prevents contact.

What maintenance or replacement will the LS26500 need later?

The non-rechargeable lithium thionyl chloride cell has a 10+ year shelf life and under 3 % self-discharge per year; when voltage drops below the device cut-off, replace the entire 6-pack.

What limit appears first under sustained use of the LS26500?

The maximum recommended continuous current is 150 mA; exceeding this causes voltage sag and reduces the 7.7 Ah capacity well before the 85 °C temperature limit is reached.
