I saw a link to them on the RV forum. Should have bought this many years ago. I usually only changed the batteries at a certain time and now I can hopefully extend that interval. I'm not sure how accurate an amp/CCA meter can be, but it provides easy verification and confidence before heading into an RV, boat, tractor, ATV, etc.
