Topdon BT20 battery tester

I will be returning it, I feel I could get better for $24

The app seems more euro themed, you have to input Amp or Amp Hours, something not every USA market battery has marked
I just noticed it's on this battery today
The more you know 🌠
It shows you voltage, and some crude indicators of if that voltage is ok
The app paired quickly and easily, but it just doesn't give the info I was looking for
I'm used to the parts store/dealer Midtronics like tester that you input CA/CCA, temp compensation, and it gives you a CCA+volt readout, and suggests what you do next

This just gives you loaded/unloaded voltage
Which I guess is better than nothing, but not really enough for me
Some of the $30-$40 battery testers operate a little more like the ones I'm used to, I'll return this and get one of those

I mean, I guess it works 🤷‍♂️
It's just not quite what I was hoping for
