T-Box NiMH Batteries

NiMH Backup Batteries for Automotive T-Box & Telematics

A vehicle T-Box (telematics control unit) manages GPS tracking, remote diagnostics, emergency eCall and connected-car communication, and it needs a reliable backup power source to finish an emergency call or data transmission if the main vehicle battery is cut. Weijiang Power supplies custom nickel-metal hydride (NiMH) cells and compact packs engineered for T-Box backup power across wide automotive temperature ranges.

Why NiMH for T-Box backup: NiMH offers dependable high-rate pulse output, strong wide-temperature performance and long calendar life in a small, intrinsically safer package than lithium — matching the long service life and reliability expectations of automotive electronics.

• Wide temperature tolerance: cells formulated for cold-crank and hot-cabin conditions, supporting reliable operation across broad temperature swings.
• Compact custom packs: 1.2 V cells assembled into the exact voltage and footprint your T-Box module needs, with tabs, leads, connectors and protection configured to the PCB.
• Stable long-term readiness: low self-discharge options and roughly 500–1000 cycles keep the backup available over years of standby.
• Automotive documentation: CE, RoHS, REACH, MSDS/SDS, UN38.3 and IEC 62133 support, with cells to IEC 61951-2.

Provide your T-Box module's standby duration, pulse current, voltage and space envelope and we will design the matching NiMH backup pack. See our industrial custom NiMH capabilities or request a quote and sample.
