FOXWELL BT705 Car Battery Tester 12V 24V, Automotive 100-2000CCA Battery Load Tester Analyzer, Digital Cold Cranking Charging System Alternator Tester for Heavy Duty Truck Boat Marine SUV ATV

Easy to use and great tool to have in your grab bag of what if tools

Cable long enough. Tell you voltage and battery life. It functions well. Good value.

Great battery tester, so far. I was using a volt ohm meter and an older battery tester, load tester and voltmeter combo.The BT-705 battery analyzer is a perfect replacement. The tester is compact, solidly built and easy to use. I love that it also analyzes the alternator. The long cable allows the operator to test with the meter inside your vehicle. One person testing, no need for help. Great price for an excellent battery analyzer and super fast shipping. Also, the BT-705 comes in a very nice storage case. Don't delay, buy today.

Let me begin by saying I'm a DIYer. There are so many battery anylizers and testers available it begs the question which one to pick. Below is my list of Pros and Cons for this tester are:Pros:1 - The tester itself feels like its made of good quality materials.2 - Its larger and gives you the industrial feel.3 - The buttons are easy to work and the software is easy to follow.4 - The length of the test leads is awesome.5 - The storage case is durable and will protect the tester foreverCons:1 - The bluetooth printer feature only connects to the foxwell printer. (I assumed it would connect to any bluetooth printer)2 - It only stores that last test. I have read that other testers will store the last 50 to 100 tests. This would've been nice.3 - The price is a little high for what you are getting compared to the others on the market. I dont think the extra lead length and the case are worth double the price.Testing Experience:1st test - my first test was on a car that is only driven for short trips and the battery is less than six months old. I expected the results to be that the battery needs to be charged. The tester reported the battery as bad and needed to be replaced. I charged the battery for the day and tested again. The tester changed its mind and said it was a good battery, the cranking was good and the charging system was good.2nd test - this test was completed on my daily commuter car. The test results were good battery needs to be charged . I had no expectations for this battery. I looked to be original, so it could've gone either way.3rd test - this test was completed on a marine battery (Engine Battery) that has been hooked up to a battery tender all winter. The test results returned a good battery4th test - this test was completed on another marine battery (House Battery) that has been on a battery tender all winter. This battery is rated for 600 CCA. The tester reported a good battery that measured 900 CCA. I'm not sure how this can be or if its safe or if the tester is wrong.If this could've printed to any bluetooth printer and if it could store more than just the last test i would've given it 5 stars. I have learned of some inconvenient work arounds for the cons that will work with any of the battery testers on the market. The only reason i gave it 4 stars is because of the length of the test leads. The length of the test leads is with a full start by themselves. The leads allow you to perform the test from the driver seat of the vehicle which is a huge convenience. If this tester only had the short leads like all the others I would've given it 3 stars and purchased a cheaper unit that does the samething.

Works for what I needed. Fast good price. Great name brand. I also have a Foxwell analyzer

Money well spent so much that I am going to get a second one. I saw this used in project farms video where he was trying to salvage old batteries and allowed him to check the overall health of the battery. This did exactly what I needed with no nonsense and relative ease of use. It let me know the health of a battery that was in question which was not in good health at all. As a bonus it confirmed the alternator was putting out good voltage and was healthy. What a relief to know I didn't need to spend almost 400 bucks on an oem alternator for a specific Japanese auto brand and just needed a $200 quality battery to solve the issue.

Like some of the other negative reviews, I'd like to report that I too get random 36 volt readings, some 18 volt readings, and the classic "loop back" when I follow the prompts but, instead of performing the test, the menu restarts from the beginning. Not always, just enough times to be annoying. All this means is that I don't know whether I can trust this instrument when it goes through the test sequence and spits out its evaluation.Note that there is no apparent explanation for this behavior in the manual, so the user is left to wonder what's going on. Also, there is no useful info on the web that I can find and I have no intention to email some Chinese person and be told to check the connections. By the way, I checked the connections a million times, it's not that. In fact, a much cheaper battery tester was able to go through the testing sequence without any problems with the clips piggy-backed to the Foxwell clips. Proof positive that it's not the connections, it's the Foxwell batty battery tester.None of these complaints are unique or new. Other reviewers have pointed then out long before I did.Which means that Foxwell knows about them, or at least SHOULD know about them, and is doing absolutely nothing to fix the problem.Rhetorical question: does a company like that deserve more than one star?
