The Topdon BT300P is a professional-grade 12V and 24V battery tester equipped with a built-in thermal printer. Designed for automotive technicians, workshops, and DIY users, it accurately analyzes battery health, cranking performance, and charging system efficiency — delivering instant, reliable test results with on-the-spot printouts.
Battery Health Test
The BT300P provides clear diagnostic results for any 12V or 24V battery: GOOD, BAD, REPLACE, or RECHARGE. It measures key performance parameters including CCA value, voltage, internal resistance, and displays theState of Health (SOH) and State of Charge (SOC) for a complete evaluation of battery condition.
SOH reflects the overall battery health compared to its optimal state.
SOC indicates the battery’s current charge level relative to its capacity.
Cranking Test
Quickly assess whether the vehicle’s electrical system can generate sufficient power to start the engine. The BT300P measures both loaded and unloaded voltage, identifying weak batteries or starter motor issues before they cause problems.
Charging System Test
Evaluate the charging system performance on 12V and 24V vehicles, including alternator output, rectifier function, and diode integrity. Determine whether your system is overcharging, undercharging, or performing optimally.
User-Friendly Operation
Featuring a 2.4” color LCD screen with backlight, the BT300P provides clear readings in any environment. Simple navigation buttons make it easy to perform tests and review results. The built-in thermal printer allows direct printing of diagnostic data — no ink, ribbons, or cartridges required. Just replace the standard thermal paper when needed.
Safety and Compatibility
The BT300P supports all major battery rating standards including CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, and GB. Compatible with lead-acid, AGM flat plate, AGM spiral, GEL, and deep-cycle batteries, it ensures safe operation with spark-proof and reverse-polarity protection.
