Btw..thanks for the tip.I bought vgate icar 2 on ebay for $15. Not sure if it's mx+ or not but it's working as expected. The only dowside is you have to turn it on every time.
I bought a OBDLink MX+ ($99 on Amazon)
using their app I got the following:
battery is 87% capacity...
So there is no way the battery can be bad..
I used the app you told me about and it just gave me 31.2 Ah for my battery..which doesn’t mean much for if the battery is good or bad..
But I appreciate the input
