eCall standby power solutions.
As the core part of the automotive emergency system, the emergency eCall backup battery uses a Li-SOCI2 battery(Lithium Thionyl Chloride) or Li-ion battery technology in automotive-grade electrolyte formulas. Even in extreme temperatures from -60°C to +85°C, the battery can provide an instant high-pulse discharge current to trigger the emergency call signal reliably.
Normally, the automotive eCall backup battery remains in a low-self-discharge standby state with the least power consumption. It can offer a shelf life up to 10-15 years. In the event of a serious accident and a main electrical power failure, the eCall battery can power the vehicle’s communication GSM/4G/5G module to send an emergency signal – enabling timely, life-saving assistance.
T-BOX power solutions.
The Lithium T-Box battery features a wide temperature range from –60°C to +85°C. In global deployment, it operates stably under low-temperature environments below zero and high-temperature vehicle interiors up to 85°C. Featuring zero maintenance without the need for charging and monitoring, it can greatly reduce the maintenance cost in remote areas. With its compact size and light weight, a maintenance-free automotive battery can be integrated into the constrained space seamlessly. The battery is in compliance with the mandatory regulation of 10-20 minutes of independent power supply after accidents. The battery maintains an ultra-low 1% annual self-discharge rate. No battery replacement is required throughout the vehicle’s entire lifespan.
Smart GPS Tracker Backup Battery Solutions
GPS battery is a type of small and high-reliability backup power source integrated into vehicle systems to enable Global Positioning System (GPS) performance.In the event of stolen vehicles, the GPS tracker battery can power the tracker to report the vehicle’s location continuously. Even if the main battery is disconnected, the car GPS tracker can still perform anti-theft and tracking capabilities.
The battery for fleet management trackers can be customized for your unique demands in a flexible size and a wide temperature range.VTCBATT can offer a specially engineered GPS tracker backup battery in different battery chemistries, power consumption, product cost, and harsh environments. Li-polymer GPS battery can support up to 1000+ cycle life and 3C GSM burst. A rechargeable GPS tracker battery should be integrated with a smart BMS for safety protection. Our superior TI fuel gauge ICs (such as BQ41Z5) enable battery data to be real-time data. You can precisely monitor the SOC, SOH, temperature, cycle life, voltage, capacity, and internal resistance. It gives you full visibility into battery health and performance.
High-Performance TPMS Battery Solutions
VTCBATT’s TPMS batteries utilize lithium thionyl chloride (Li-SOCl₂) chemistry for maintenance-free operation in harsh automotive scenarios. The high-temperature TPMS battery can perform normally even under the harsh environment of extreme temperatures from –40°C to +125°C. Its internal solid construction is specially designed against strong vibration. The TMPS battery in low-pressure can keep a stable voltage output around the nominal 3.6V. Featuring an ultra-low self-discharge rate (1% per year), TPMS battery life is designed for over 10 years. With decade-long reliability, it reduces maintenance costs for TPMS battery replacement. Under high G-forces within the tire, the VTCBATT automotive battery for TPMS can prevent power supply interruption and sensor failure. With a 10C pulse capability(e.g., 1A for 10ms), the battery can deliver high-rate current to power the NB-IoT and BLE sensors.
As an ISO9001 and IATF 16949 certified battery manufacturer, we provide the precision and durability required for Tier-1 automotive OEMs. VTCBatt TPMS solution can not only reduce the total cost of ownership, but also enhance road driving safety.

Typical batteries used in automotive electronics include Li-SOCl2 batteries for long-life applications, lithium-ion and Li-polymer batteries for rechargeable systems, and Li-MnO2 batteries for medium power devices. The selection depends on power consumption, lifetime, and operating conditions.
For GPS tracking devices, Li-SOCl2 batteries combined with hybrid layer capacitors (HLC) are widely used. They provide ultra-low self-discharge for long service life and support high pulse current required during data transmission.
Because communication modules such as GSM or LTE require high pulse current, a capacitor is used to handle these short bursts. It prevents voltage drop and ensures stable device operation.
Battery life can range from 2 to 10 years depending on reporting frequency, temperature conditions, and battery capacity. Low-power design and proper battery selection are key factors.
Yes, specially designed lithium batteries can operate in a wide temperature range, typically from -40°C to +85°C, making them suitable for harsh automotive environments.
Primary batteries (such as Li-SOCl2) are designed for long-term use without recharging, offering very low self-discharge. Rechargeable batteries (such as Li-ion) are suitable for applications with frequent power usage or external charging availability.
Battery capacity should be selected based on device power consumption, reporting frequency, and expected service life. A power consumption profile analysis is usually required for accurate selection.
Voltage drop is typically caused by insufficient pulse current capability of the battery. This is common in devices with wireless communication modules and can be solved by adding capacitors.
Yes, lithium batteries designed for automotive electronics include protection features such as overcharge, over-discharge, and short-circuit protection, ensuring safe and reliable operation.
Most lithium batteries used in automotive electronics are maintenance-free and designed for long-term deployment without user intervention.
