Check your vehicle's 12V battery and charging system before a weak battery leaves you stranded.
The Satrayana BT-172 Battery and Alternator Tester provides a clear digital voltage reading together with colour-coded status indicators, making it easier to understand the condition of the battery and alternator output.
Simply connect the red clamp to the positive battery terminal and the black clamp to the negative terminal. The tester powers up automatically and displays the measured voltage on the bright LED screen.
Dedicated battery indicators show Full, Medium, Low or Empty status, while the alternator section helps identify whether the charging output is High, Good or showing a possible fault. Reverse connection and overvoltage indicators provide additional guidance if the clamps are connected incorrectly or an unusual voltage condition is detected.
The attached copper-coloured alligator clips provide a secure grip on the battery terminals, while the integrated 35cm leads keep the tester ready for quick checks at home, in the garage or in a workshop.
Product Features
Digital Voltage Display
The bright LED screen shows the measured battery voltage clearly, making results easy to check in garages, workshops or low-light conditions.
Battery Condition Check
Colour-coded indicators provide a quick visual reference for:
Alternator Output Test
Helps check the vehicle's charging-system output and displays High, Good or Fault status.
Reverse Connection Warning
A dedicated indicator alerts the user when the positive and negative clamps are connected incorrectly.
Overvoltage Indication
The overvoltage light helps identify unusually high charging-system output.
Strong Alligator Clamps
Copper-coloured clamps provide convenient and secure contact with compatible battery terminals.
Integrated Test Leads
The attached red and black leads are approximately 35cm long, keeping the unit compact and ready to use.
No Complicated Controls
Connect the clamps to the correct terminals and read the voltage and illuminated status indicators.
Quick 3-Step Test
- Connect the red clamp to the positive (+) battery terminal.
- Connect the black clamp to the negative (-) battery terminal.
- Read the voltage and battery or alternator status indicators.
For an alternator test, follow the vehicle manufacturer's safety instructions and check the charging-system reading while the engine is running.
Understanding the Indicators
Blue - Full / High
Indicates a fully charged battery status or high alternator output.
Green - Medium / Good
Indicates a moderate battery level or normal alternator output.
Red - Low / Dead / Reverse / Fault
May indicate a low battery, discharged battery, incorrect clamp connection or charging-system fault.
White - Empty
Indicates an empty battery condition or insufficient detected charge.
