Review: Must have item in households - I have been pleased with this battery tester so far. The item came packaged well and feels built to last. This is a great tool and must have item in households in my opinion. It's a simple way to check the health of your battery and other components such as the alternator. The cost of this item is probably what a garage would charge to do initial investigation on your charging system. Therefore after about 2 checks, you have made your money back. Time will tell how good this battery tester is, but for the time being I am pleased with this purchase.
Review: A must have tool - Needed this for my EV 12v battery test. Excellent, easy to use meter which proved its worth when it said my battery was ok after 3 years. It should be changed according to the service plan, but is just a money generator for the main dealers. This proved its worth and saved me the price of a new battery which is not cheap. I urge you all to buy one for peace of mind to see whether your battery is winter ready!
