iCARZONE MA500 12V/24V Car Battery & Charging Tester
The iCarzone MA500 is a professional-grade battery testing tool engineered for simplicity and pinpoint accuracy. It delivers comprehensive, fast analysis of 12V automotive batteries as well as 12V/24V starter and alternator systems. Whether you are a DIYer, car owner, technician, or managing a fleet of heavy-duty trucks and construction equipment, the MA500 provides the reliable electrical diagnostics you need to keep vehicles moving.
See every reading on the 2.4″ screen.
From a tired battery to a failing alternator, the MA500 puts a plain-language verdict on screen in seconds. Tap through its core jobs to preview exactly what you’ll see.
For Battery Health
Clip on or plug into the OBDII port and the MA500 reads the battery in seconds — State of Health, State of Charge, resting voltage and internal resistance, with a clear GOOD / REPLACE verdict you can act on right away.
Built for the toughest jobs — and the simplest.
From a single passenger car to an international fleet of heavy-duty trucks, the MA500 gives DIY owners and professional technicians the same fast, trustworthy verdict in seconds.
Commercial-Grade 24V Support
Engineered to handle both 12V passenger vehicles and 24V heavy-duty trucks, trailers, and commercial machinery.
5-Language Global Interface
Seamlessly switch between English, German, French, Spanish, and Italian—perfect for international workshops and diverse fleets.
Fast, Accurate Results
Advanced conductance technology detects failing cells and shows clear results in under 5 seconds.
Plug & Play
Draws power directly from the OBDII port or battery terminals under test — no internal battery to charge or replace.
Safe, Passive Operation
Passive conductance testing produces no sparks, no heat, and virtually no battery drain — safe and easy to use at any skill level.
Everything you need to judge a battery — and what’s charging it.
Two complete test suites in one tool: a full read on battery condition, and a deep look at the cranking and charging systems behind it.
Comprehensive Battery Health Analysis
Full Health Metrics
Measures State of Health (SOH), State of Charge (SOC), and internal resistance to assess battery condition and remaining life.
In-Vehicle Testing
Run tests directly under the hood without disconnecting or removing the battery from the vehicle frame.
Smart Temperature Compensation
Automatically adjusts readings based on ambient temperature for reliable accuracy in any climate.
Definitive Cell Assessment
Pinpoints damaged or dead cells rapidly, giving clear instructions on whether to recharge or replace.
Alternator & Cranking System Tests
Dual-Voltage Cranking Analysis
Evaluates 12V and 24V starter systems to ensure the engine draws optimal power during ignition without disabling the system.
Smart Charging System Tests
Analyzes 12V and 24V alternator outputs under different loads to ensure the battery is receiving stable charge currents.
Intuitive Ripple Voltage Test
Displays charging ripple parameters to quickly uncover hidden faults in diodes and voltage regulators.
One tester for the whole fleet.

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 MA500 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 MA500 features advanced passive conductance 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 MA500 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.
No. The MA500 is dedicated to battery health and alternator/charging-system diagnostics. If you need engine fault-code reading and clearing, please see our upgraded model, the iCarzone MA900.
