We both have something to offer here, for others to consider, or not. Based on what Tester said several years ago, I simply invested in a cheap version for maybe $60. Takes about 30 seconds to test a battery and I’ll check the cars and mower several or more times a year. May not be as accurate as the expensive equipment, but if you keep track of the readings you can definitely see when it’s time for replacement. So ya don’t have to spend a lot of money if you are a novice. Kinda like you don’t have to have a $200 socket set for a home owner. --- _[View the full topic](https://community.cartalk.com/t/12v-battery-reads-good-voltage-but-no-amps/162824)._
