  • Excellent Two-in-One Tester!
Not only does it check your battery and charging system, but it also checks for engine error codes. Well worth the price!

  • Great product for great price with 2 in 1 device
The media could not be loaded. This review is long and please be patient with me. I am a professional technician with almost 20 years of experience. This device impressed me when I opened the box. There 4 parts: device, OBD II cable, battery tester cable, and USB cable for the update. It works like a champ when came out of a bag. These are 2 devices in 1 unit: an OBD II scanner and a battery tester. There is no internal battery in it. It was powered by a vehicle battery to turn it on. First is scanner: scanner works like every OBD II global scanner with Read codes, clear code, monitors readiness, live data, graphing data... and it is very fast responding but no testing available. Second is the battery tester: this tester is very accurate so far. I had a customer come to our shop with concern about dragging start, the vehicle still starts every time but she said feels like a hiccup before it starts. I put this tester on her battery and did the test. the result shows need a new battery even her battery voltage shows 12.80V but the amperage isn't enough causing the dragging start. Then I test a new stock battery on the shelf it shows "Good battery" even though its voltage was lower than her battery. if you notice on the device: Red LED means "need replace battery" Green means "Good battery" and I think Orange means "charge retest". I used this device for 3 days in a busy shop, and all my technicians and lube techs love it. I think Topdon had been listening to all reviews from people who used BT100 and they did some improvements: longer battery tester cable, the cable attached to clamps had been secured by a metal clip, preventing the cable from breaking off like BT100, and when you hold the up and down to select CCA, the number didn't jump to hundred like BT100 instead jump every 5 unit. However, I think Topdon can make it better if they use Bluetooth for OBD II. Switching from OBD II to battery tester cable is OK for DIYers but for technicians is annoying and chance to damage the device when you switch 100 times a day. The conclusion: Pros: fast OBD II scanner, accurate battery tester, affordable price Cons: (actually not more like a recommendation) annoy me when switching from cable to cable, hopefully Bluetooth device for OBDII with be improved on a later device. Hope this review helps someone out there looking for 2 in 1 device that won't break the bank. I will follow up and update this after couple months to use this device to see how it stands up in a rough environment. ... show more

  • This is a life saver for a weekend warrior or intermediate car tech
Got this scanner to check active monitors before the cars get sent off for a smog check inspections, as a bonus it has an option to check the baterys as well which makes it super nice. And noticed it has an option to check o2 sensors individually due to misfire, you get to know what exact sensor to replace then removing them and testing manually. Top Don nailed it again. Never disappointed😃 ... show more

  • Bang for your buck!
I keep this unit in my car. When I get a service call, this is the first thing I use. I can check no starts with ease and speed! Everything from a low or bad battery to fuel pump or ignition problems. Gives live data which is a must! Fir quick basic, and sometimes in depth, diagnosis this is a valuable resource! ... show more

  • TO GET THIS TOPDON LOAD TESTER AND OBD SCANNER FOR UNDER $100 IS UNBELIEVABLE! GREAT INVESTMENT
This this is AWESOME! Battery load tester does it all plus you can send results to a printer for your customers. Test battery, charging, and starting systems. The OBD SCANNER is very handy! Compact but very capable. Even has a trouble code lookup so no more pulling out the phone to look up codes! For price, size, and capabilities I give this a 9/10. (Only think that could make it better is a built in printer.) GREAT INVESTMENT! ... show more
