Features

1.【6 & 12 Volts Battery Tester】 As the upgraded version of KW600, KW650 can test all 6V and 12V 100-2000CCA batteries including regular flooded, AGM flat plate, AGM spiral, or gel batteries. The perfect automotive battery testers to diagnose the batteries of car, boat, lawn mowers, etc. Perfect for Father's Day Gift.

2.【One-key Waveform Analysis】The exclusive function on KW650 battery analyzer is the voltage waveform analysis, for the beginners, it helps to track the real-time voltage changing to find the battery issue, for the professional repair store, it’s continuous voltage monitoring results can be uploaded to computer then compare it to achieve the analysis of in-car systems.

3.【 >99.9% Accuracy】Thanks to KW650’s powerful STM-32 chip, it provides more than 99.5% precise testing reports within milliseconds(testing results refer to US Midtronics), greatly improved the testing speed compared to other battery testers. Besides KW650 is one of the few automotive battery and alternator testers that supports UPDATE function.

4.【Display Overall Batteries Data】Except give you the basic battery parameters such as voltage, internal resistance, cold cranking amp, battery health and charge status, KW650 load tester will also give professional advice based on these data then you can decide whether to replace or charge the battery, help you know battery status in advance to prevent possible battery failures.

5.【Starter& Alternator Tester】KW650 is not only a great battery load tester that tests batteries cranking & charging system but also can test alternator's charging and starter's cranking conditions. And it can switch up to 12 languages for different needs.

How to determine if the battery is good or needs to be replaced?

Plug and Play: Enter the rated capacity of the battery. The KW650 begins with analysis of the CCA (or AH) value, the charge (%), the voltage (v), the internal resistance (Ω), the rated power and battery status (%) of the battery and shows the test result on the screen within seconds.

The result of the battery test includes 5 types:

1. Good battery:

The battery is no problem, use it without worry!
Good to charge: Good battery but low power, charge before use.

2. Good to charge:

Good battery but low power, charge before use.

3. Replace:

The battery is already or shortly before the end of the service life. Please replace the battery.

4. Bad cells, replace:

Battery internal damaged, defective cell or short circuit, replace battery.

5. Charge test:

Instable batteries must be charged and tested again to avoid errors.
