TOPDON BT50 Car Battery Tester

Works and does its job, perfect and affordable little tool to add to my tool chest. I am a DYI proponent and have been learning a few things here and there. My car’s battery kept dying (car that I don’t drive daily), when I drive it regularly, the battery was OK, but died if I didn’t drive it for a few days. This tool diagnosed the issue with the old battery and I replaced it. Had a. We battery in storage for a few months, charged it and it was diagnosed as a good battery.

Outstanding! It tells you everything that you need to know about your battery In one simple step. And this is what sold me...at the end of its testing sequence (which doesn't take long at all),it tells a positive yes or no if the battery is good or bad. Nice!

I swapped out the battery on our 2012 Chrysler 200. Battery uninstalled was 12.2 volts and only 339 CCA out of a rated 550 CCA.New battery 12.2 volts, 559 CCA. 40 years of automotive here. I own an Autel scanner. I could've purchased the battery attachment for Autel scanner, which is Bluetooth. But it was $175.00 For the money, ease of use, you can't beat this thing. No, getting out my scanner, no pairing up (Bluetooth) hook it to the terminals and you're good to go, easy Peezy, reliable.

Hi, I only have this a couple of days so far so good as far as the battery test goes, seems to be close enough to what my multimeter voltage readings say. I've been charging my battery and testing as I go with TOPDON BT50 and my meter ,so far voltage readings are close enough with both. I haven't been able to do the crank /charging tests as my battery isn't hooked up to my car, because I'm still charging up my battery with a charger so I'm only able to do the battery test, these other tests will come later on and I'll update when battery is back in car. As far as ease of use, this gadget is so easy to use you could do without the small manual. As of now, I can say I recommend it, very handy and seems to work great ,only gave 4 stars because I wasn't ready to run the other tests due to battery not being in car. I will update.

Very impressed. I’ve got the Snapon but I use the Topdon more because it’s quick and small. The Snapon will provide more data when used with amp clamp but most times I just need a quick check of a battery

Very simple to use, tells me strength of the battery and can get a sense how soon I will need to replace. Also tell me how effective my battery charger is in regenerating mode in restoring health of the battery.

It is a very good product and is exactly as described

Great
