TLM batteries

TLM (Tadiran Lithium Metal) is an advanced lithium technology developed for applications that require high power discharge after long periods of storage.

The technology combines:

• High energy density
• Low self-discharge
• Ability to deliver high current when needed

It is particularly suitable as a backup power source in systems that may be inactive for long periods of time.

While Li-SOCl₂ is primarily optimized for low and stable loads over long periods of time, TLM is designed to handle higher power discharges directly from the cell, without the need for an external capacitor solution.

TLM provides:

High power capacity upon activation

Fast voltage response

Stable performance after long storage

TLM is often used in:

• Automotive telematics systems
• Emergency call devices (eCall)
• Backup systems
• Security and alarm systems

These applications require high power immediately, even after many years of inactivity.

TLM technology is designed to deliver high power even after long periods of storage. Low self-discharge means that capacity is retained over time, while the cell can be activated quickly when required.

This makes the technology well suited for use in regulatory demanding systems where the battery is only used in emergency situations.

When specifying, the following should be considered:

• Power discharge requirements (A)
• Duration of pulse load
• Permissible voltage drop
• Temperature profile
• Requirements for service life and storage
