has been a leader in the automotive industry offering a wide range of battery testers, all of which have been hailed as reliable and innovative. This BT300P showcases the same brilliant design and quality as other BT series testers:

Often you get stranded in the middle of nowhere with no mechanics nearby, all due to a bad battery, right? This car battery tester BT300P is a cost-efficient method to test your battery, making sure it has enough juice to drive the car before you hit the road.

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.

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.

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

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.

This car battery tester is a handy tool to ensure your batteries are always working at an optimum level. Worthy as an addition to the toolbox collection for automotive mechanics, 4S repair stores and battery manufactures.

This automotive load tester comes with a great carrying bag, which fits the unit itself quite well to provide extra protection against bumps or accidents, and is dust-proofing. It is also perfect to store in your glove box.

Package list:

1*BT300P; 1*Carrying Bag; 1*User Manual; 3*Printer Paper.

This advanced battery tester will automatically turn on as soon as being connected, welcoming you with a bright and nicely pixelated 2.4” color screen. It will present quality test result that is quick to read in a dark garage, under the hood, or even under natural daylight.

More, the built-in printer is there when you feel the need to attach a printout to a work order. You can print the test result out directly, share it with your customers or keep the printing records for future reference.
