Foxwell BT705 Feedback Yes & No:

  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.
  1. 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!


  1. 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.


  1. 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.


  1. The manual was written well with easy to understand instructions.


  1. BT705+ Bluetooth Printer: Tester is simple and easy to use/set up. Printer battery is typical of latest technology batteries was difficult to get its first charge established but now works well. Printer is not housed in the tester’s case which exposes it to not being protected. Manufacturer seemed oblivious to needing to protect it. Typical example of marketing types and field users never meeting. Having a printed report for my clients is a nice touch. Being thermally printed it will be copied to preserve it. Handy.
