Overview
The LM26500 C-size lithium manganese dioxide ($\text{Li-MnO}_2$) battery is engineered to deliver reliable, long-lasting power for demanding industrial, medical, and remote applications. Designed with a high-energy spiral cell construction, the LM26500 handles both continuous moderate-drain power and high pulse current demands (up to 4.0A) without experiencing significant voltage drops.
Whether deployed in harsh outdoor conditions or left in long-term dormant storage, the LM26500 maintains exceptional performance due to its wide operating temperature range (-40°C to +85°C) and ultra-low self-discharge rate.
Key Features & Benefits
-
High Pulse & High Drain Power: Excellent high-current response designed specifically for devices requiring short radio frequency (RF) transmissions, telemetry bursts, or high-peak current draws.
-
Long Shelf Life: Features an extremely low self-discharge rate of less than 1% per year, giving it a multi-year operational and storage life.
-
Extreme Temperature Endurance: Operates reliably in frozen environments or high-heat conditions without capacity degradation.
-
Safe & Hermetically Sealed: Built with a stainless-steel container, glass-to-metal seal, non-corrosive electrolyte, and integrated safety venting to prevent leaks.
-
No Voltage Lag: Unlike some lithium-thionyl chloride chemistries, $\text{Li-MnO}_2$ provides an immediate, stable voltage output even after long periods of inactivity.
Common Applications
The LM26500 is the trusted power source for mission-critical and remote electronic devices, including:
-
Smart Utility Metering: Automated Meter Reading (AMR) for gas, water, and electricity meters.
-
IoT & Telemetry: Remote monitoring devices, GSM/GPRS tracking systems, and asset trackers.
-
Security Systems: Wireless alarm sensors, perimeter monitors, and emergency transmitters.
-
Industrial & Military: Field radios, beacons, marine equipment, and specialized sensors.
-
Medical Equipment: Portable diagnostics, patient monitoring tools, and memory backup systems.
Frequently Asked Questions
Is the LM26500 battery rechargeable?
No. The LM26500 is a primary (non-rechargeable) lithium manganese dioxide ($\text{Li-MnO}_2$) cell. Attempting to recharge this battery can cause severe damage or leakage.
What is the difference between an LM26500 and an LS26500?
While both are C-size lithium cells, the LM26500 uses Lithium Manganese Dioxide ($\text{Li-MnO}_2$, 3.0V), which is optimized for high pulse currents and high-drain power. The LS26500 uses Lithium Thionyl Chloride ($\text{Li-SOCl}_2$, 3.6V), which is designed for low-current, long-term standby applications. Always verify your equipment’s required voltage before replacing.
