• 12V&24VBattery Tester  The BT300P is a quick and accurate battery tester that offers printed diagnostic receipts. Know everything about the health of 12V batteries, the 12V & 24V starter motor’s cranking status, and 12V & 24V vehicle electronic system’s charging condition. This is TOPDON’s newly developed battery tester that ensures your batteries are always working at an optimum level.
• Wider Application This device works on a wide variety of 12V automotive lead-acid batteries, such as 100~2000CCA regular flooded, AGM flat plate, AGM spiral, Gel, and EFB. It detects the failure of the starting and charging systems in 12V & 24V cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, and even lawnmowers. Most vehicle issues caused by a defective battery can be fixed with the BT 300P.
• Fast & Accurate Test Results Featuring TOPDON’s latest conductive battery testing technology, this modern battery tester can identify the exact reason why your battery failed in only 3 seconds. Research shows that its results provide an accuracy of 99.5% - more precise than competing battery testing equipment.
• User-Oriented Battery Load Tester Its 2.4” color screen shows crystal-clear readings at any lighting condition. Intuitively placed buttons allow you to toggle menus with ease. With the built-in thermal printer, you won’t have to worry about running out of ink. No ribbons, cartridges, or other supplies are needed for its use. Standard thermal paper is the only refillable supply required to print your test results.
• Extra-Safe Operation With spark-free copper clamps, PVC-coated wiring, and built-in automatic protection against reverse polarity, the BT300P provides the extra safety you need when battery testing. Its insulated ABS shell prevents current leaks and can withstand damage. With an extra-long 31.5” cable, this car battery tester is even more convenient to use.

Battery Health Test

Our digital battery testers can help you diagnose faults with direct test results: “GOOD, BAD, REPLACE, or RECHARGE”.

Simply connect the tester to check battery health condition: CCA value/rating, voltage, internal resistance, state of health (SOH), and state of charge (SOC).

• State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions.
• State of charge (SoC) is the level of charge of an electric battery relative to its capacity, SoC is normally used when discussing the current state of a battery in use.

Cranking Test

Set this battery tester to cranking test mode and then start the vehicle.

The result will tell if your 12V & 24V electrical system can generate enough power to start the engine.

• Loaded Voltage means the voltage measured when turning on on-board electrical appliances, such as headlights.
• Unloaded Voltage means the voltage measured when turning off all the on-board electrical appliances.

Charging Test

Use this load tester to routinely check your 12V or 24V charging system of vehicle, to gauge alternator health and troubleshoot charging issues.

Fast & Accurate

No more lagging behind and false test results. This 12V battery tester runs super-fast and adopts cutting-edge conductance testing technology for 99.5% accuracy.
