Product Description

Car batteries usually last three to five years but can die suddenly. Even if your battery appears charged, it could be weak. Warm weather and regular driving can conceal this, but cold temperatures or neglect can lead to starting issues. It's crucial to get a battery test with a BA101 to be sure.

ba101

Winter surprises shouldn't include car battery troubles! Say goodbye to uncertainty with BA101. When winter hits, your car batteries can be unpredictable. By the end of every winter, you're left wondering about their condition. BA101 takes the guesswork out with a quick and accurate test

    Accurate & mostly easy to use
    Easy to use and test your battery. I compared results with my multimeter and my carbon pile load tester and it was accurate. Doesn't put a "load" on your batttery per se, but does estimate its max load capability by sending electronic current through it and measuring resistance. Screen is easy to read and has contrast adjustment options for you to tweak how you like the display. One of the best things about this unit is that it doesn't need its own power supply! It runs on whatever battery you hook it up to.Only issue I ran into was trying to print out my battery report (if you are interested in doing this - many won't need this option.) I docked one star for this. If you are not tech savvy, you may have an issue. You have to download a driver and the print software off their web site for your particular unit. Find the proper site in the small print in the manual because there is more than one site for this company. After doing that you have to figure out how to display the print software in english because it is in chinese. Google how to spell english in chinese and then select that in the language drop down list in the print software. Then you have to select the right Com port in the software dropdown list (trial & error works here.) Then you have to "open port" through the software, and then you have to select "print screen" on your Ancel unit. Finally, the last test result will populate the print software screen where you can then print it. Hope this helps. Having a paper report would be a valuable option to take with you to the battery vendor when trying to warranty a battery because their tester might read good and this report would give you extra ammo if you will.

    The AGM battery on my BMW was 10 years old so I was curious if it was time to replace it. It was cranking a bit slow, but the standing voltage was about 12.8 after a good drive so I was not sure if it was going bad. I purchased this tester and it said I had 13% health left on it and recommended replacement. The tested voltage was 12.7V, about what I had read with my Fluke, which just goes to show that standing voltage is not indicative of a good battery. Just to make sure, I took my battery into O'Reilly Auto Parts and tested it there, and it gave pretty much the same result: 15% health and 12.6V standing voltage. So the inexpensive tester appears to work just as well as the testers at the auto parts stores. Installed new battery, and it tested 100% health and 12.8V standing voltage. Tested on my wife's car battery which I had just replaced 9 months ago, and it confirmed it was 98% health, which seems correct. Tested on my son's AGM battery which we had replaced 2 years ago, and it was 90% health. Again, seemed about right.

    I did not realize that a simple voltage test does not tell you if battery is good or bad. This tester appears to put a load on the battery to see how well it handles the load, and gives an indication of health based on that, as well as the battery's internal resistance.

    So really happy I purchased this. Good item for my tool chest.

    I’ve been interested in a conductance style battery tester for quite a while. A video review of this I recently saw suggested that this both provided repeatable results and could be used for smaller AGM batteries like you would find in UPS applications.

    The trick is to look up the peak current delivery rating for the UPS battery. Then hook up the meter directly to the battery terminals and this powers up the meter. For UPS batteries, I selected out of vehicle tests, CA (not CCA, unless your batteries are really cold), then adjust the CA rating to match the peak current rating of the battery. A few seconds after the start, it comes back with state of charge percentage, and voltage, battery health percentage, and peak amps. It also provides an internal resistance measurement that is good to compare with the battery spec page.

    This meter was able to confirm that 2 UPS and one jump starter batteries I purchased 2 years ago and have charged a few times a year are still very healthy, while confirming both batteries in one UPS claiming bad batteries were both very deficient in current delivery, about 20 times the expected internal resistance, and based on voltage just coming out the UPS, one of them had 2 shorted cells. The test cycle still ran, and provided numbers, but suggested charging and trying again. The other UPS, one battery tested clearly defective, but the other one still showed good amperage, and only slightly high internal resistance, so it may well find a use in a different project.

    So far, this meter is providing data consistent with what I would expect, that is repeatable, and working on earning my trust.

    Do note that this apparently won’t work on many jump start battery packs, likely because the battery charger circuitry appears to interfere with the measurement. Though opening the case and disconnecting the battery should provide a good reading.

    Reviewed in Canada on April 14, 2020
    LATEST UPDATE: The Ancel folks got the virus out of their print software, and appear to have gotten the issues with their web certificate fixed as well. Now all is good! I upped the rating to 5 stars, which it now deserves. It's great to be able to print out the test results of your battery, cranking system and charging system and show it to your mechanic. When testing your battery, you can use the CCA, or cold cranking amps, setting and set it for the number of cold cranking amps your car has. This is a great feature. There are a number of places on the Internet to find the CCA rating for your battery. Anyway, this BA 101 unit has become a mainstay in my "car tool bag" for keeping tabs on the battery and charging system. It will let you know if your alternator is in the act of biting the dust, or if your battery needs to be replaced. It's better to replace a dying battery on your own schedule than to wait until it dies in a parking lot in a blizzard! This has to be better than most of the testers on the market. Scotty Kilmer, in his Youtube channel, raved about another scanner that did not have all the capabilities of this one. Oh--if you got the CD with your scanner, don't use it--go to the web site at anceltech.com and download the latest drivers and software. That way you won't get anything loaded on your computer (for printing) that should not be there!

    UPDATE: I received a response from Anceltech's customer support team. She assured me that the software did not contain a virus and they would try to fix their web site so Norton anti-virus would not recommend against going there. Well, I tried the web site this very day--and I get a message that the web site's certificate is not valid. So, that issue is not fixed. Until it is, I'm not going to try to download the software again. This is an example of how a company could make a potentially great product, but mess up big time by having an invalid web site certificate, and allowing someone to stick a virus into the software. The software for printing was kludged together in any event. Now, I think the tester itself is great, and you could use it without printing out the results. But I hate it when a feature is advertised and that feature is so problem-laden that it doesn't work properly. So, Anceltech has two very simple things to fix: (1) its web site certificate and (2) cleaning the virus out of its software. Why this is so difficult for them I cannot imagine.

    I got this battery and charging system tester because I have been having trouble with the battery in our Ford. The Ford dealership had the car in its shop on two occasions, first taking a month to replace a defective engine, and second, taking three weeks to procure and install a new flywheel in the transmission. At neither of these times was the battery put on a charger. The battery is a Motorcraft premium battery with a 36-month free replacement guarantee---but a week ago I had to get a boost from CAA because it was dead as a doornail. I took it to my mechanic and it tested as good after about a week of driving it every day. But then I got this Ancel battery tester and hooked it up to the battery. Two days ago, the tester showed 100% healthy battery, but zero charge! Today, after more driving, it was up to 12% charge. So tomorrow I'm taking it to the mechanic to have it put on a battery charger all day long. Apparently this battery may have sulphated or otherwise just not got back up to a full charge. If driving it 30 km a day for a week doesn't charge beyond 12%, I know something else is needed. So--stay tuned! I will let everyone know what the tester says after a the battery gets charged up on a trickle charger!

    UPDATE: I am lowering the rating to two stars. The battery tester itself is GREAT. However, when you try to access the manufacturer's web site at anceltech.com, Norton Antivirus warns you that it contains a Trojan. Well, I accessed the site anyway, because I was having printing problems, and sure enough--Norton detected a virus inside the software I downloaded. Now, again, the device itself is great--it will tell you things about your battery that are missed by a Snapon unit costing hundreds of dollars. But the manufacturer needs to scrub its web site. Possibly the little mini-disc also contains a virus or malware of some time. You shouldn't get a virus or malware on your computer from visiting the company's web site! When the manufacturer cleans up its software, I will revise my rating accordingly--but right now using the company's software can put your computer at risk.

    3.0 out of 5 stars マニュアル

    多機能でよいと思うがマニュアルが日本語ではない。購入前は日本語の選択ができるものと思っていたが英語、ポルトガル語、フランス語程度で須戸と残念。しかし、マニュアルがなくても意味が分かるので使っている。装置は玩具のように感じてしまう。

    5.0 out of 5 stars Super easy and fast

    Very impressed with this gadget. Very easy to use, and much better than the cheap resistive load testers.
    It tests batteries -- flooded, agm, spiral agm gel. The test takes only seconds and it gives a readout showing what percentage of the battery life remains, voltage, internal resistance, cranking amps. The test can be done with the battery attached to the vehicle, where the starter motor and the charger are also tested...or out of the vehicle.
    The only disappointment is that the software for printing results on a personal computer with a cd drive doesn't appear to work, at least not with Windows 10. Only a minor things, as the readouts are all available on the unit's display.
