Description

The Roadi Battery Tester can be used to test a wide range of 12V batteries including Starting, Lighting, and Ignition (SLI), Deep Cycled and Marine (Flooded), VRLA or Maintenance Free (MF), Sealed Maintenance Free (SMF), Absorption Glass Mat (AGM), and GEL cell. The major battery standards JIS, SAE, EN, DIN, and IEC are supported. BA101 12V car battery tester can easily, quickly and accurately measure the actual cold cranking amps capability, the health status of the battery itself, and the common fault of the vehicle starting system and charging system. The Roadi Battery Tester Advantages: Simple and easy to useTests batteries on and off the vehicleAccurate results in millisecondsBattery life analysisAnalysis results: Good or ReplaceLarge easy to read LCD screenTest results based on JIS, EN, DIN, SAE and IEC StandardsQuick test - inputs battery volume (AH), then shows battery statusVehicle cranking system test - cranking time, voltage and statusStore the testing result and the print functionVehicle charging system test—load voltage, unloaded voltage, ripple status, and charging system status. It can test by AH and CCA values but also applies to other test standards such as BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.If your battery standard is AH standard, you can input the AH value to test in the "Quick Test" menu.If your battery is CCA or another standard, please input the CCA or other value to test in the "Battery in Vehicle" or "Battery out of vehicle" test menu. It adopts the world's most advanced conductance testing technology to date for accurate and authoritative test results.It quickly analyzes the data, usually taking 2-3 seconds to display the results.Easy to use, it can quickly and accurately identify battery problems. Before using the print data function, it is necessary to connect the tool to a computer via the USB cable. Once ready, please insert the CD to the computer.Install the USB driver first.Open the print software, and choose the COM Port NO.Then choose the function of print data to start printing.

With the protective case, you can safely take or store the tester anywhere you want. with LCD backlit screen, you can see the data clearly even in the dark. With a USB cable and CD driver attached, you can print the test data if you want to. ✔ Cranking (starter) Test Roadi battery tester will also quickly and accurately test the cranking voltage and cranking time. Normally the cranking voltage lower than 9.6V is regarded as abnormal. If the cranking voltage is too low, the battery may become weak. If the cranking time is too long, check the oil and engine. ✔ Charging System Test Roadi Battery tester can not only test alternator charging voltage (load/unload status) but can test the healthy status of rectifier diodes. Normally the maximum charging voltage varies in 14.7+-0.5V. Diodes' ripple voltage varies in 0~200mV If the charging voltage is too high or low, check the regulator ( more info in the user manual) Regularly test your charging system to prevent the battery from overcharging or discharging, effectively protecting the battery and increasing battery life.

  • Easy and accurate but drains the battery
Size: Small
This was simple to install and download the app and gives accurate updates but I seriously doubt it draws "only 1.5 mAh". The battery in my camper typically holds 100% of its charge for weeks at a time, as soon as I attached this meter, it lost almost 1% of charge per day. I now have to disconnect it between uses which defeats the ability to have the information readily available through the app. ... show more

  • Had some issues.
Size: Small
Didn’t like the charging test at low and high idle. Required to shut off the car and sometimes it doesn’t pick up. Try to test with the car running and the ap tells you to start the car? Very touchy with the timing.

  • Not much bluetooth strength
Size: Small
What I was hoping to use this for won't work. I have a seldom driven truck with a dashcam which runs all the time. I am having dead battery issues after the truck sits for awhile. I was hoping that I could install this at the battery with the truck in the driveway and be able to monitor the battery in the house. While I can remotely see the battery voltage on my phone, I have to be within 8 feet of the truck for the bluetooth to connect. If I have to stand next to the truck, I might as well look through the window at the volt meter I added to the dash. Maybe if you have an application where the Battery Monitor doesn't have to be behind metal you might have better results. ... show more

  • Great device! Works very well.
Size: X-Small
I used this to diagnose a occasionally dead battery in one of our cars. It was one of those maddening slow discharge situations that only is only noticeable if you leave your car sitting for a week or more. With this device I could tell when the battery was discharging slowly allowing me to systematically find the culprit. The device is simple to install and the app is fun (for something as unexciting as battery charging/discharging). ... show more

  • App issue
Size: XX-Small
This app does not work on my galaxy note 10+ 5g yet but the developer is working on it. Until then it works with my tablet. Will be perfect when it works on my phone for notifications.

  • Tool to quickly see how my RV batteries are functioning
Size: Small
Product was very easy to hook up to my dual batteries on my rv. Definitely has limited Wi-Fi range. I actually have to be out next to the RV in order to have any app work. Startup check of voltages let me see how batteries are functioning.
