BA101 Car Battery Tester 12V Auto 100-2000 CCA Battery Load Tester | Automotive Alternator Battery Analyzer Digital on Cranking Charging System, for Motorcycle, Truck, Boat, RV, Marine & More

It’s looks really do hide a truly great performing battery tester. A very good range of tests, all carried out with the most important factor - accuracy. Others on the market do ‘look’ better, where this just works as it should, and at a very good price point. The only way it could be improved would be the inclusion of a suitable storage case in place of the small card box it arrives in. Low cost and high performance. Superb little tool to have about.

Load testing the health of your car battery CCA (Cold Cranking Amps) and whether the battery can retain the charge is important to know when having diesel vehicles especially for those colder mornings - don't get caught out!. It's easy to use, does what it says and clearly displays the results. I've always used the multi-meter method for checking the alternator charge but this does that to. I'm not intending to use the report and download feature but that could be useful in a commercial sense. I Should have bought one of these tools years ago.

Very handy piece of kit for small money. Had a battery go bad on a vintage vehicle. Tried charging but the CCA was gone to low on the battery.

Have so many batteries around. Project farm vid said this is best for the £. Looks like all my old batteries are no good! No real way of double checking. But does say known good batteries are good. Recommended.

Great little tester. Easy to use and really accurate too. You need to know some basic info about your car battery type and capacity (can usually be found on your battery if you don’t know) Reports battery health as well as state of charge and voltage. Can also test your car’s charging system (alternator) to see if the cars charging the battery You can also run a cranking test to see how the battery performs under load. There’s a good review of it on YouTube (projectfarm) if you want to see it beat other models much more expensive than this one.

Simple to use but accurate and most importantly gives internal resistance. I bought a brand new Bosch batter from EuroParts and when I got home, before fitting it to my car, tested the battery. It showed 72% health and 9.54 internal resistance. Charging it overnight did not make any difference. I took it back and the guys in Europarts were brilliant, no quibble, they got out another Bosch battery and that too tested 87% health. Finally a cheaper "own brand" (I think made by Lion) and this showed 99% health so I bought that instead and save myself £20. After charging overnight it now tests 100% health and all other tests are perfect. I will never purchase a new car battery again without my test meter. There is no other way of knowing how "good" the battery really is without knowing things like the internal resistance. The battery test meter used in the shop by Europarts looks expensive and produces a nice paper print out of the results but it does not test internal resistance so is really a waste of time. Incidentally, testing the 2 year old battery in my son's car also showed 100% health.

Good value for money

Works perfectly and a very reasonable price Would definitely recommend

This is a solid tester that, from my several tests, gives reliable results. The build quality feels sturdy, and I like the clear and easy-to-read display. The compact size makes it convenient to store and use. I appreciated the simple interface and the accuracy of the readings. One thing I liked is how quickly it evaluates battery health. The ability to test both batteries and alternators was another highlight. The cable length is decent, offering flexibility when connecting to a vehicle. The clamps are durable and provide a good grip on terminals. A small drawback is that the menus can take some getting used to, especially if you're unfamiliar with such tools. It also doesn't come with a carrying case, which would have been a nice addition for storage. Overall, it works exactly as expected and has been a dependable part of my diagnostic tools. It's a no-nonsense, efficient solution for anyone who needs quick checks.

Dies what it is supposed to do

I gave this 5 stars because it does exactly what I want a battery tester to do: it takes the guesswork out. Instead of wondering whether the problem is the battery, the charging system, or something else, this gives me a quick answer without dragging out a bunch of other tools. What I like most: It is easy to use, gives clear readings, and covers the information that actually matters. I like that it can check battery health, state of charge, cranking performance, and charging system performance all in one tool. That makes it useful not just for confirming a bad battery, but also for catching alternator or charging issues before they turn into a bigger headache. Useful features: Another big plus is that it works with a wide range of 12V lead acid batteries and supports plenty of battery rating standards, so it is more versatile than a one-trick tool. It also reads internal resistance, which is a feature I really like because it gives a better picture of battery condition than voltage alone. The fact that it can test on or off the vehicle is also very convenient. Why I bought it: I like having a tool like this around because it can save you from replacing parts blindly. A good battery tester pays for itself quickly the first time it helps you confirm whether a battery is actually bad or still usable. Bonus: Project Farm even did a video on battery testers, and that gave me even more confidence in this one. It was clearly one of the standout options in terms of value and real-world usefulness, which matched what I wanted. Bottom line If you want a battery tester that is easy to use, gives you more than just a basic voltage check, and helps you make better decisions before spending money, this is a great one to own. Easy 5 stars.

Werkt, moet me multimeter niet uithalen en telkens met de settings zitte spele

Update:// 23.09.25 Das Gerät funktioniert tadellos. Nach Rücksprache mit dem Kundendienst, wurde mir problemlos geholfen! Sehr guter Kundenservice!! Ich bin jetzt voll und ganz zufrieden mit dem Gerät. Die Messergebnisse liegen jetzt auch in der Toleranz! Klein, handlich und praktisch. Ideal wäre noch eine kleine Packtasche beizulegen!! ————————————- Alte Bewertung: // 15.09.25 Das Gerät ist eigentlich gut verarbeitet, aber leider versagt es auf ganzer Linie! Die Messergebnisse für die Batterieleistung weichen leider extrem ab. Es wurde mit einem Werkstattgerät verglichen. Entweder habe ich ein defektes Gerät gehabt, oder die Software ist einfach noch nicht richtig ausgereift.
