Purchased this Ancel BA301 battery tester after first ordering the BA101 Plus model. The BA101 Plus seemed to be outdated and the instructions to the website links to download the Print software weren't correct. The clamps also were inferior. Please see my review of that unit for more details. The BA101 Plus battery tester was returned. The BA301 battery tester had similar features and actually worked using the instructions to download the software. The clamps on this unit were slightly different with the tips exposed beyond the plastic cover so that they would work on an installed GM style side mount terminal battery, using the side of the clamps to contact the battery terminal bolt head. The tests worked well too and confirmed a marginal battery. The test results were easily saved to my PC. Overall I am pleased with this battery tester and would recommend it.

This is a must have. Well made, easy to use, fast. Great value for the purchase price. Found out I had a bad charger and not a bad battery.

I work in the motorsports industry (motorcycles, ATVs, UTV's, PWCs, etc.) and have specialized testers for the batteries used in these products, but I didn't have a tester for larger batteries and decided to try this one from ANCEL. Once received, the first thing I noticed was that it is easy to operate, even without reading the manual. You basically just have to hook it up to a battery and follow the onscreen commands. (The backlit screen is easy to read.). Instead of writing these steps out I have provided some screenshots below that show the different screens you will encounter when checking a battery. (see 1st 4 pics) *Battery Type: 12V Model *RESULT: Replace Battery *VOLTAGE: 12.38 V *INT RES: 14.12 mΩ (internal resistance, anything over 10 is not good) *SOH: 15% (state of health) *CAP. Act: 198 CCA (current cold cranking amp capacity) *CAP Std: 500 CCA (rated cold cranking amp capacity) *DATE/SER. NO: 00000000 (insert date here if you want) At the end of the test you can choose to print the test results, a sample of a tested bad battery below. Note: The printer uses thermal paper which requires no ink. This tester can also test the charging system of your vehicle, providing results of the charging system while the vehicle is running with a load. I've included a few screenshots below and will update this review once I have had a chance to use these features more. (see last pic) Overall I think this is a very nice battery tester and charge analyzer. It is very easy to use and the ability to print out the test results either for your own personal reference or to attach to a customer repair order is extremely handy. The only slight negative is I wish it came with a case, but cases are cheap so this is not a big deal to me. I will update this review once I have used this tester a little more.

As a service adviser, this is a great tool to have in your arsenal when you can quickly grab and test a battery and give a print out to show the customer. Of course at the shop, we do have professional Snap-on equipment to test batteries, but can never find it when you need it in a hurry. So it definitely helps to have a personal item that I have handy. All in all, it works great, just as accurate as our Snap-on tester, but at a great affordable pricing. The reason why it's getting 4 stars instead of a full 5 star review is that it could definitely use improvement. I do understand that this is a budget tester that comes included with a printer when competitors are charging more than twice the amount for a printer, but small things could be done better. The "rugged grippy case" that's in the description is definitely not the case for one, it's just hard molded plastic. A little bit of rubber padding on the sides would be nice. Speaking of the case, a magnet on the back would be nice to keep the cables in check, and to attach it to a body panel while doing testing. The printer, although a very good selling feature on this unit is a bit flimsy. The paper feed slit is not very large, and paper would get curled back up inside the housing, causing you to need to open the cover to remove the printout or requiring you to first pull some paper out before printing. A larger slit or a paper feed button would've been nice. The last thing is not being able to print out readings for alternator or starter results. The only thing that's able to print is a the battery reading. With it having a printer, I would say that was a huge oversight.

Purchased to replace a battery tester that I really liked, but it failed to operate. This was a cheaper replacement so I was worried that it wouldn't work as well as the previous one. After extensive testing on every battery I could find at home, in the store, at my mechanics stock of old "bad" batteries I am IMPRESSED. After testing every type of 12v battery I could find not one failed to test correctly. My mechanic had 3 that he thought were bad that tested good with this tester, after putting them in my truck and 2 of his trucks they are still going strong with no issues. Ugly batteries aren't always bad.

Testing works fine. Printing is the problem. First, since there is no internal battery, you need over 7 volts in the battery you are testing or the printer won't work. Second, after tearing a report off, before printing the next one, you need to open the printer lid and start the paper, or the paper will jam on the lid and not feed. Still, minor issues considering the price.
