I've been using this battery tester in the shop for a long time and it works great! You can test a wide variety of batteries, start tests and charge tests. It gives good information on how many volts, CCA and if the battery is running or dying, as well as what percentage of life is left. As a techie, I would definitely recommend this battery tester to anyone looking to buy one.
