Review on Efficient Battery Tester & Alternator Analyzer for Cars - AUTDER 12V/24V Digital Car Battery Tester with LCD Display & LED Indication by Michael Ringgold

When it comes to work this battery tester has saved me so many times. When it comes to accuracy, this battery tester has always been accurate. To use I just set it to 12V or 24V, connect it to the battery and it tells me if the battery is good, low or the alternator. What I really like about this battery tester is that it not only tells me if the battery is good, bad or dead, it even tells me the remaining voltage of the battery. Not only has it helped me at work, but even my private cars. I recently bought a car for my son and when it wouldn't start I thought it was the battery. Put it in my car and it turned out to be a generator. Not only does this save me time and money, it also saves me the headache of trying to figure out what's wrong.
