This ensures precision charging and stable battery support, even during vehicle programming.

Unmatched Battery Compatibility

Suitable for a wide range of battery types including AGM, WET, GEL, MF, CAL, and EFB, the T90000 is compatible with capacities from 5 to 90 amps. Perfect for both passenger vehicles and commercial applications.

9-Step Smart Charging

The intelligent 9-step charging system automatically monitors and controls the process, eliminating the risk of overcharging. It extends battery life while providing maximum protection.

Advanced Protection – Your Battery’s Bodyguard

Built-in safety features guard against:

• Reverse polarity

• Reverse charging

• Short circuits

• Overheating

• Over-voltage

This ensures complete protection for both the battery and the vehicle’s electrical systems.

Dual Temperature Monitoring for Maximum Safety

Equipped with two temperature sensors, the T90000 continuously monitors the charging process:

• Internal sensor – tracks device temperature

• External probe – monitors the battery being charged

This dual-layer protection guarantees safe and efficient charging in all conditions.

SUPPLY Mode – Voltage Stabiliser for Programming

In SUPPLY mode, the T90000 provides a stable DC output, making it ideal for use as a programming voltage stabiliser during ECU updates or module programming.
