Description
CR26500 Battery Lithium C cell with Tabs
The CR26500 is a premium primary (non-rechargeable) lithium sulfur dioxide (Li-SO2) C-size cell built for high drain and pulse-heavy applications where dependable voltage and rugged performance matter. Its spiral-wound construction supports strong current delivery while maintaining a stable discharge profile.
What this battery is used for (common applications)
- Radiocommunications and other mission-critical electronics
- Rescue / emergency beacon devices (including PLBs and EPIRBs)
- Sonobuoys
- Military and harsh-environment equipment
Key benefits
- High drain & pulse capability for demanding loads
- Stable output voltage suited for mission-critical electronics
- Wide operating temperature range for extreme conditions
- Long storage life / low self-discharge (ideal for standby devices)
- Hermetic sealing & safety vent for reliability
Specifications (typical)
- Size: C (R14)
- Chemistry: Lithium Sulfur Dioxide (Li-SO2)
- Capacity: ~3.75Ah (application dependent)
- Voltage: 3.0V (open circuit), ~2.8V nominal under load
- Operating temp: approx. -60°C to +70°C
Important safety & compatibility notes
- Do not recharge (primary lithium cell).
- Always match voltage, size, and termination (tabs/leads) to your device requirement.
- If you’re replacing a battery pack, verify cell count, wiring, and connector before ordering.

FAQ – CR26500
Is the CR26500 rechargeable?
No. The LO29SHX is a primary (non-rechargeable) lithium sulfur dioxide (Li-SO2) battery. Do not charge it.
What devices commonly use the CR26500?
Common use-cases include radiocommunications, rescue/emergency beacon devices (PLBs/EPIRBs), sonobuoys, and other rugged or military-grade electronics.
Is CR26500 the same as a standard 1.5V C battery?
No. This is a 3V-class lithium primary cell (different chemistry and voltage). Only use it in devices designed for this battery type.
What does “high drain / pulse” mean?
It means the cell is designed to deliver higher currents and short bursts of power reliably—useful for transmit/receive cycles, signaling, and other pulse-heavy loads.
Do I need tabs or leads?
Many industrial devices require solder tabs or leads rather than a plain cell. If your original battery has tabs/leads, match that style or contact us for the right configuration.
How should I store unused batteries?
Store in a cool, dry place in original packaging, away from metal objects that could short the terminals.
