After having 2 cars have issues a Friday apart, 1 alternator the other fuel pump, both had batteries that were taxed and running out of steam. Or so I thought. 1 is an OEM agm that's just at 6 years old, so it's a stretch for life and that particular vehicle has a strong amp and subwoofer, so it puts a heavier draw on the system. The other is 6.5 years old lead acid OEM battery I thought for sure was nearing it's EOL. Well, after watching the video for Project Farm, it was down to this TopDon unit or the Ancel, but being they were both almost the same price, this unit won. The battery replacements would have been $180 each, or $360 plus tax, which would have put them at just under $400 for the pair. Rather than just jump and replace them, I figured I'd invest in this tool to be 100%sure since the big membership store doesn't do any testing or installation of the batteries. Wouldn't you know, both batteries showed good health. The oldest of the 2 actually showed full green lights, good health in the high 90% range with solid CCA readings. The other agm, it also showed good, but was in the yellow light section and was in the upper 70% range of health. This tool saved me $350-ish dollars and will serve me well down the road no doubt. Don't hesitate, this is a solid tool.

Handy little gadget. Got this to test a battery and alternator that wasn't quite working. Turns out the alternator is ok (even tested at the parts store), but the battery is getting weak. Defiantly something for the toolbox.

Replaced my BT200 which did not work with 24v as advertized and finally broke a lead. Also the systems I work on have battery charger/maintainers that conflict with some digital testers. At first this BT100 seemed to work out better giving more accurate results in my opinion. But any voltage over a certain threshold (haven't pinned it down exactly) the tester aborts and tells you to turn headlights on to lower voltage. Backup generators do not have headlights and any discharge activates charger. Disabling the charger and disconnecting the batteries is not usually feasable and can possibly damage components if not sequenced correctly. Also it is not testing the system as found. As it does not apply to my needs, it is a fine tester for a small auto shop or a DIYer. Carbon pile testers are the only true way to actually load test batteries and confirmed by my Interstate Battery rep. They are silly expensive though.

This little jewel seems to cover pretty much everything the Life and Strength of your battery, Plus check the starter draw which I have a tool that I call a little toaster because when I hook it up, it actually has a wire that glows red hot , you hold that for 10 seconds and when you release it, then it tells you the strength of your battery so it would simulate a starter cranking. It also checks the alternator current to make sure it is working correctly, for what you pay for it I think you get a very good little unit. {value for your money} It will tell you whether the battery is good bad or needs to charged just with lights plus you could look at the information and learn how to read it to get the same information but it will give you the lights and make it simpl. The cable length, could be a little longer for the starter test and alternator test because they ask you to start the engine, then change the setting to alternator test, then hold the throttle to obtain 2500 RPM for five seconds. You could sit in the car and do it all otherwise you are running back-and-forth to change the settings on the tester. I have tested 11 different batteries so far and it's read what I would consider to be reliable and accurate information on every one. I like, it's a good little tester.

I compared this tester against two others in our shop. The battery testing function is accurate and easy to use. I have not yet had a chance to try the cranking and charging tests.
