TOPDON BT300P 12V Battery Analyzer with Built-in Printer

Professional 12V battery diagnostics

The TOPDON BT300P tests 12V lead-acid vehicle batteries from 100 to 2000 CCA (30–220 Ah) using conductance technology. Within seconds it displays the state of health (SOH), state of charge (SOC), actual CCA value, voltage and internal resistance, with a clear verdict on whether the battery is good or needs replacing. Results are 99.5% accurate according to the manufacturer.

12V and 24V cranking and charging tests

The cranking test measures the starter's cranking voltage and cranking time. The charging test measures the alternator's loaded and unloaded voltage, as well as ripple. Both tests work on 12V and 24V systems.

Wide compatibility

It supports four battery types (Flooded, AGM, GEL and EFB) and ten test standards: CCA, CA, BCI, MCA, DIN, IEC, EN, SAE, JIS and GB. Batteries can be tested installed in the vehicle or out of the vehicle, on the bench.

Built-in printer

At the press of a button, the result prints in 2–3 seconds. Professionals can hand documentation to the customer on the spot, while car owners can keep a log of their battery's condition. The printer works when the battery voltage is above 9.5V.

Greek-language menu

The 2.4" color display and step-by-step menu make testing simple, even for first-time users. The menu is available in 9 languages, including Greek. The device stores the last test result for review.

Safe, portable and durable

It features reverse polarity protection and spark-free copper clamps. Weighing 475 g and built from rugged materials, it is easy to carry around the workshop or on roadside calls in the included bag.
