User questions & answers

Question:	Can i test my truck battery

Question:	What does it mean when the Alternator State is blank (no lights) even when the engine is on / revved to 2000 rpm
Answer:	Either you have a defective tool, it is improperly connected to battery terminals, or your alternator is not producing an output. Use a volt meter to determine if your alternator is functioning. This tool is just a quick tester time saver.
Question:	Will this work on batteries that are not connected to a car? I store batteries for my boat during the winter months and want to test them b4 instal
Answer:	Yes, this will work on car batteries, but in my opinion, a battery that just is not connected and sitting by itself is not a good thing. I would say that you need to purchase a trickle charger, (they should not cost an arm and a leg and are small, but to what they are designed for). Just one that puts out around 1-2 amps and keep on the batteries when not in use, because a battery that sits just may go bad from not having an electrical charge going through them, just rotate the charger from battery to battery every 1-2 weeks if you have more than one and you should be good to go as when you test them. I have had many batteries go DEAD when they just sit around with nothing electrical attached to them and at least getting a small amount of a charge. By doing this, your batteries should all test Good when you get ready to reinstall them. Hope this helps.
Question:	The check engine light came on my car, what should i do? repair shop wants to charge me over $200 to fix

User questions & answers

Question:	will this work on my 2000 Toyota Prado dieselwith 1KZ engine
Answer:	Hi there, I am with BAFX Products. Sadly it will not read any ABS/SRS?VSC or any other codes. The only codes it is able to read are those which cause your vehicles "check engine" light to illuminate. Any other lights require more specialized tools for reading. Best regards, BAFX Products
Question:	Will this work on a Nissan X trail T
Answer:	yes, I'm using Windows Phone 8 on Nokia 920 with OBDAutoDoctor application. You need to connect the PIC18F2480 via Bluetooth, before starting an OBD2 scan tool application. On Windows Phone 8 only a few OBD2 app are available. OBDAutoDoctor is free but get only some information from the car. I just found how to unlock the pro version...It's a in-app purchase...click "..." at the bottom of the app to upgrade. The Pro version is available for $7.99.
Question:	i used this tool and all is said was manufacturer control. no code number with it? what does that mean? 1998 ford explorer sport
Answer:	Hi Christopher - I am with BAFX Products Support.In MOST vehicles you will be ok leaving the adapter plugged in as long as the vehicle is driven every few days. However we make the following recommendations:1) Do not leave the adapter plugged in if it will not be driven for 24-48 hours2) If your area is to be experiencing extreme cold unplug the adapter as the combination of cold and the adapter will drain it faster3) If your battery is more than a 1-2 years old you will want to be very careful about leaving it plugged in, older batteries do not hold the same juice as the newer ones4) If you have an electronics heavy vehicle such as BMWs tend to be we do not recommend leaving it plugged in as the vehicles electronics do not always fully power down either5) If you have any other device plugged into the vehicle while it is off via cigarette ports or whatever we then also recommend removing the adapterI hope that these tips and information are found helpful. If you have any further questions you may always reach out to us through the Amazon messaging system at any time!Best regards,BAFX Products Support
Question:	Can you use this to diagnosis why check engine light is on and figure out why car wont start? even of car wont start
Answer:	I can confirm that this adapter WILL read (I haven't tried to clear yet) ABS codes on Ford (2001 Ranger 4.0L), using FordSysFree or MotorDataOBD Free (both Android). ABS codes are in the Cxxxx range. Mine picked up, correctly, C0034 - Front Right Wheel Speed Sensor Failure. While other adapters may be able to read these codes with other Android Apps, this ELM327 BAFX adapter does capture ABS codes for Ford. That is the only one I can confirm. Yes, FORScan for PC should also pick up these codes with this adapter. I have not tested Torque PRO, but I don't believe it will read ABS codes with this adapter.

User questions & answers

Question:	Will this device measure amperage in 6 & 12 volt deer feeder batteries? We have batteries that show good voltage but don’t work. Need to check amps
Answer:	It doesn’t measure amps. It puts a 100 amp load on the battery and you can see how much the voltage drops.
Question:	Is the switch momentary or does it stay on
Answer:	The switch is just to test the load on the battery it is spring loaded and stays in the off position .
Question:	Is this made in america
Answer:	i'm sorry to say, this is not made in america. that was the first question i had when i went to replace my old one.ther are only a few that are made in usa and they are more than $300. so they got us over a barrel, you buy this one for under $50 or the next one up is $300. that's what they mean when america does make anything anymore. we do make stuff, but its huge money and priced right out of the market. the us govt needs to step in, tax the crap out of this south east asia stuff so the price would be $150, then the us companies could compete cause they could sell alot more at a lower price. but the us companies dont see those kind of sales numbers, so its hard to compete in a free trade market. so, all in all, the answer is no.
Question:	This is the same unit they sell at harbor freight for 20 bucks right down to the switch, do your self a favor and buy the schumacher instead. tom

Replace Your Bad Battery In Time:

Generally, a battery dies and you replace or charge it, but it is hard to tell when a deep cycle battery is going to die. This 12 volt digital battery tester gives you the information about the life of your batteries, instead of guessing, or vaguely remembering when it was last replaced or charged. It also allows you to test a battery to see if the problem is the battery or your charging system before spending money for replacing parts unnecessarily.

With this little household battery tester, you can check the battery by yourself just in seconds, and avoid the hassle of driving to repair shop to find out if your battery is good or not. The most important thing is, it makes you know the problem and replace the battery in advance before it leaves your car dead on road.

1. Any questions or problems, just write to us via online messages, we'll reply to you within 5 hours on average.
2. Please note that this battery tester CANNOT test 6v/24v batteries.
3. If you are testing inside a vehicle, make sure all accessory loads are cut off, the key is not in the ON position and the doors are closed.
4. Do not connect the tester to a voltage source greater than 18V DC, otherwise you may damage the tester.
5. If you want to adjust CCA rapidly, just hold on up/down button.
6. Please note that this battery tester for car can't do load test and deep cycle.
