Cranking test: analyze the actual required cranking current and cranking voltage of the starting motor.
Charging test: analyze the charging system, including generator, rectifier, rectifier diode, etc., which it give you reliable data for your reference. If one of the above mentioned parts is not in normal situation, it will lead to over charge or incomplete charge of the battery, thus the battery will be quickly damaged and also greatly shorten the using life.

Foxwell BT-705 FAQs
Q: Will Foxwell Bt705 check starter draw? What type of infomation will it give?
A: I have run Foxwell Bt705 test only one time since I got mine so haven’t explored all of its functionality yet. The starter test gives the voltage while cranking, cranking time until start and an ok or faulty reading if I recall correctly.
Q: is the power pack for the bluetooth printer 220 volts or 110 and does Foxwell Bt705 need an adapter for usa sockets?
A: the power adapter input: 100-240VAC 0.7A 50/60HZ, output: 9V-2000mA. And the power adapter in the US Macket is UL CSA.
Q: Will Bt705 accurately load test atv batteries?
A: Yes, it can accurately load test car batteryes.
Q: So can i also use Bt705 with the car running in order to see if the alternator is charging the battery? and is there a way to use to test starter?
A: Yes, you can view the charging status while running, but it will not test the starter. Best way to test the starter is using an inductive amp clamp…so that means buying another tool.
Customer Feeback on Foxwell BT-705
1.So far really like this tester. I just received it and only used it once. Tested battery CCA and Charging circuit. The charging circuit test has you ideal/rev with no load and same test with load (lights, fan, radio etc.) while in park. Pretty cool. Will update if I find any problems with it but by the feel and look of it this will be a long lasting tester.
2.I work at a Lexus dealership. We have a shop supplied MidTronics battery tester that costs over $1,000. I am incredibly impressed by the features offered on this model for around $100 in comparison. It does all of the same things such as battery tests (via CCA, JIS, ETC), a starter test, and alternator output. Very impressive. Would recommend!
3.I tested this out on 4 different cars with known good systems and all came back accurate. They either tested bad or charge and retest. The tool is laid out well and the interface is very user friendly. I took this to work and tested numerous battery cores with expected results.
4.The only downside I see is that the cables may be the weak spot here, they are built into the tool and not detachable. I am not sure if you can get new leads for the unit or not so that could render the unit useless prematurely.
