ANCELBA101 Car Battery Tester, 12V Digital Automotive Alternator Meter Diagnostic Tool,100-2000 CCA Load Capacity, Charging & Cranking Analyzer for Truck, Boat, RV, Marine Vehicle, and More

Works like a champ. Price is right.

Works great, simple to use, small and compact enough to stick in your pocket if you want. Got mine on one day delivery, delivered just a little while ago, took it out and tried it on my F250 and worked perfectly. I highly recommend.

Easy to use for testing battery and charging system.I just used it to test the battery in my f150.As suspected the battery had only 29% life. The battery still has some pro-rate warranty left From NAPA. Now I have proof of "failure".Handy info to have.

Works great! Helped me save some money on my diesel. Not the batteries ($500), it was a weak starter ($141). This little gadget zeroed in on the issue

Wonderful item. I used it the day that I got it to check my battery and since it was a new battery it checked out great.

Good product, easy to use.

So far so good works like it should very pleased with it so far

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.
