Autel MaxiTPMS TS508 Lithium-ion Battery: The Power Core of a High-Performance TPMS Diagnostic Tool

In the modern automotive repair field, TPMS (Tire Pressure Monitoring System) diagnostic tools have become essential equipment for tire servicing and vehicle safety inspections. The Autel MaxiTPMS TS508, a popular TPMS diagnostic and service tool, relies heavily on a key component—a high-performance lithium-ion battery.

This power source, designed specifically for professional environments, allows the TS508 to maintain stable output in various repair scenarios.

Battery Specifications

As the power source for the TPMS diagnostic tool, the Autel MaxiTPMS TS508's built-in lithium-ion battery boasts precise specifications and robust performance.

The device uses a 3.7V lithium polymer battery with a capacity of up to 3200mAh.

This battery specification is above average for professional handheld diagnostic devices, sufficient to support a full day of TPMS diagnostic and service work.

Compared to traditional lithium-ion batteries, lithium polymer batteries offer a lighter weight and more flexible form factor, allowing the TS508 to accommodate a large-capacity battery cell while maintaining a relatively compact size (215mm x 105mm x 37mm).

The device weighs only 0.39kg (approximately 0.86 lbs), minimizing fatigue even during extended handheld operation.

Regarding operating temperature, this battery functions normally in environments ranging from 0°C to 50°C (32°F to 122°F), covering most repair shop conditions.

Its storage temperature range is even wider, from -20°C to 70°C (-4°F to 158°F), ensuring it won't easily be damaged even in extreme environments.

Charging and Battery Life

The Autel TS508's charging system is designed with the needs of professional repair environments in mind.

The device comes standard with an AC adapter and a USB charging cable, providing multiple charging options.

In the repair shop, technicians can quickly charge the device using an AC adapter; when on the go, it can be recharged via a vehicle USB adapter or other USB power sources.

Regarding battery life, the 3200mAh battery capacity provides the TS508 with extended operating time.

According to user feedback, under typical workloads, a single charge can support a day of moderate-intensity use.

This significantly reduces charging time and improves work efficiency for tire shops or repair workshops that need to continuously perform TPMS sensor activation, diagnostics, and programming.

The device also features an automatic power-off function, automatically entering sleep mode after a period of inactivity, effectively avoiding unnecessary power consumption and further extending the battery's single-charge life.

Battery and Device Performance The battery, as the energy foundation of the TPMS diagnostic tool, directly affects the performance of various functions of the device.

The TS508 has two TPMS service modes—Quick Mode and Advanced Mode.

In Quick Mode, the device performs basic TPMS functions, such as checking TPMS sensors and quickly programming MX sensors.

In advanced mode, the device can perform complete TPMS diagnostics, sensor programming, and position relearning.

Stable battery power ensures reliable performance in both modes, especially during high-power operations such as OBDII relearning and TPMS diagnostics.

The TS508's TFT color display (320 x 240 dpi) consumes a significant amount of power during operation. High-quality power ensures clear display and responsiveness, allowing technicians to easily read sensor ID, battery status (supported by some sensors), and PSI values.

Stable power delivery from the battery is particularly important when performing MX sensor programming.

The TS508 supports two programming options: "Auto Create 1-16" and "Copy By OBD." These operations require a continuous and stable voltage output to ensure programming success rate and data integrity.

Usage and Maintenance Recommendations Proper charging practices can effectively extend the TS508 battery life.

It is recommended to use genuine accessories (including the original AC adapter and USB cable) for charging to avoid potential damage to the battery from unstable current.

Storage and operating environments are equally important for battery life.

Although the TS508 is designed for storage temperatures as low as -20°C, long-term storage in a dry, room-temperature environment is recommended to avoid irreversible damage to lithium battery activity caused by extreme temperatures.

When the device is not used for extended periods, it is recommended to charge it periodically to maintain battery activity—storing lithium polymer batteries in a fully discharged state for extended periods will accelerate aging and capacity decay.

Updates to the device software are also crucial for maintaining the efficient operation of the entire device (including the power management system).

The TS508 can be updated for free via USB connection to a computer, and the official software updates also optimize device power consumption.

It is worth noting that the TS508WF model (an upgraded version of the TS508) also supports updates via Wi-Fi. It is recommended to connect the device to a power source during updates to avoid interruptions due to insufficient battery power.
