Powered by advanced conductance testing technology, it delivers pinpoint precise results in about 5 seconds.
Plug & Play — No Battery Required
Draws power directly from the vehicle’s OBDII port or battery terminals. It’s always ready when you need it.
Safe by Operation
Features built-in short circuit, reverse polarity, and over-voltage protection. Engineered to prevent sparks, overheating, and battery drain.
5-Language Global Interface
Seamlessly switch between English, German, French, Spanish, and Italian. Ideal for international repair shops and multilingual fleet management.

Both models share the same battery and charging-system test suite — SOH/SOC health checks, dual-voltage 12V/24V support, in-vehicle testing, smart temperature compensation and a ripple voltage test, all with free lifetime updates over USB. The MA900 adds OBDII engine fault-code reading and clearing on a larger 2.8″ screen; the MA500 keeps things focused on battery and charging diagnostics.
Good questions, clear answers.
No. The MA900 is completely plug-and-play. It draws power directly from your vehicle’s OBDII port or battery terminals, meaning it never runs out of battery and is always ready for a test.
Absolutely. The MA900 features advanced conductance testing technology. It can test batteries directly under the hood without removing them, and it is 100% safe—guaranteeing zero sparks, zero heat, and zero battery drain.
All software updates for the iCarzone MA900 are 100% free for life with no annual fees or hidden subscriptions. You can easily download the latest firmware via our official update tool to expand vehicle databases, optimize performance, and unlock new software features.
A linking error usually means the tool cannot establish communication with the vehicle’s computer. Please check the following:
• Ensure your vehicle’s ignition is turned to the ON position (or start the engine).
• Check that the OBDII connector is securely plugged into the vehicle’s port.
• Verify that your vehicle is fully OBDII compliant.
