AUGREXKW208 12V Car Battery r, Automotive Battery Load r, 100-2000 CCA Auto Cranking & Charging System Test, Display Diagnostic Checker Scan Tool Digital Battery Analyzer for Truck Marine SUV Boat

Bought for work, gets used DOZENS of times per day. Leads could be shorter, but nothing a zip tie can't fix.

VERY easy to use. Just need to know your CCA of your battery and kind. Many YouTube Videos to show you how it works, etc. Tried it today, and it worked GREAT! Plan to check my battery every 3 months since the hot sun down here in Texas tends to "eat" batteries after 3+ years. Worth the investment. Instructions very simple. Worth the money! Great Value!!

I have several auto and sports batteries to check. This device does that quickly and easily, however since it does not apply a load to the battery I really have no idea how accurate this extrapolated data really is. I probably am going to have a couple of my batteries checked at one of the auto store chains to see how close the results are to this device, but haven't done that yet. I will say the voltage reading is somewhat higher than my VOM which I trust more, but not by a lot. If it pans out that the readings somewhat mirror the store reading than I will feel more comfortable with the results this checker provides.

Worked great. Instructions don’t describe how to check alternator. You can find it in YouTube. Accidentally ordered 2. Liked it so much going to keep both. One for shop and one for home.

I would recommend it.
