Cranking Test

If your battery is 4 or more years older, and it does not seem to crank your engine at a normal speed, you probably need a new battery.

This 12V battery tester can show you the cranking voltage, and the cranking time in milliseconds, to help predict if the battery will fail to crank/start the vehicle.

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 battery load tester to check if the generator provides sufficient power to the vehicle electrical system, and if the battery can hold the charge.

More data are also included: CCA value/rating, voltage, internal resistance, state of health (SOH), and state of charge.

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.

Show Battery Health

This automotive alternator tester will display test results: “GOOD, BAD, REPLACE, or RECHARGE”, concise and easy to understand for your quick reference.

 

• GOOD BATTERY: Battery is in good condition, no worries!
• GOOD, CHARGING: Good battery but low voltage, charge before using.
• REPLACE: Battery almost reaches the end of the using life, please replace it for car running.
• BAD CELL, REPLACE: REPLACE: Battery is interior damaged, bad cell or short circuit, replace it.
• RETEST AFTER CHARGING: Low voltage, charge and retest to avoid error.

In / Out of Vehicle

This car battery tester has a fast scan time to run a battery system test to check battery overall health, and the status of your alternator and battery.

Stay Safe Always

The risk of causing damage tends towards zero when using this load tester.

At the end of the durable cable are larger-sized clamps than the competition for a more secure fit.

Easy Battery Tester

This entry-level auto battery analyzer is made for newbies, with helpful features such as extra-large clamps for a solid connection, intelligent LED status indicators for quick test, and 5 large keypad buttons that make the menu easy to scroll.

**Move off the clamps and wait for 2 minutes to do another test.

2 Test Methods

• In Vehicle – no need to remove the battery. You can directly check the vehicle battery under the hood.
• Out of Vehicle – can test the independent battery.

Can Work in Hot & Cold

You live in someplace where the weather is harsh? Then you need this durable car battery tester, which can stand the extreme cold and heat (operation temp. range: -4℉~140℉, -20℃~65℃).
