    Customer Product Reviews

    Rated 4.4 out of 5★ by 128reviewers.
    Rated 5 out of 5★ by Stunning Effectiveness I had no intention of writing a product review for Walmart but after witnessing the success of the Diehard 80/20/10/2 at resurrecting a 2 year dead battery back to full life, I had no choice but to pass on my advice - buy this if you want your money's worth!I originally purchased this (via online order/ship to store, which worked great and helped me avoid checkout lines) to maintain intelligently through the winter the newish deep cycle marine battery I bought in the spring. But before hooking up to the good battery, I thought I would put the Diehard to the test of its claimed ability to sense a bad battery and start a desulfation process. Sure enough, when I hooked it up the Diehard told me the battery was at 0% (in spite of being "charged" a few times 6 months ago). It then went to work, and stalled at 20% charge, but did not flash a failure so I let it continue to work. 2 hours later it jumped to 76%, but stalled there again, with no failure indications. I rode it out for 4 more hours while it sat at that number and then it suddenly started climbing bit by bit all the way to 100% Voila a new backup battery.How can you beat that? 10/24/2013
    Rated 5 out of 5★ by fills all our charging needs. We have a small farm and lots of different batteries. Most of the time one of them is dead. We need quick start as well as trickle charge. It is a great product. It is the second one we have owned. Lightning got the other one. Unplug it when not in use!! 03/12/2011
    Rated 5 out of 5★ by This product has a lot of features that other chargers do not have and at a good price. 03/06/2011
    Rated 5 out of 5★ by Awesome value and awesome Charger I own several older or antique cars and when they sit around for a while the batteries have the tendency to loose some of it's power, now I just plug in my charger put it on the boost mode and you are ready to fire it up!! Or if you are charging a battery that has been dead for a while, just put the charger on it's lowest setting ( 2 amps ) and let it charger for a while and watch how a dead battery comes back to life. Dollar for dollar this is the best charger for it's value. I even dropped my charger accidently from on top of the fender of one of my cars and it survived without a scratch. Now that's a true value for your dollars!! 12/01/2013
    Rated 5 out of 5★ by Excellent buy Does everything I need it to and then some. I had to pay more than I wanted to, but the extra features are helpful. 02/07/2011
    Rated 5 out of 5★ by Excellent product This charger has even more options on it than expected or stated in online description. We are VERY satisfied with it. Already used it and very happy with its performance so far. Big test will be this summer on marine battery, but am sure it will perform with excellence. Great product at a more than reasonable price!! 01/21/2014
    Rated 4 out of 5★ by Does the Job The charger is pretty much plug it in and make the simple connections and switch it on. You get an LED reading of Percent Charged and Voltage. It turns off automatically and gave my dead auto battery a second chance. The first attempt on slow trickle charge gave a false completion reading and turned off. The car started but it did not fully charge the battery. I used a quicker charge and it brought it back to life @100%. Also this is not portable in the sense that you can carry it in your trunk for roadside emergency starts= you need a nearby 110V plug. The power cord could be longer. I needed an extension cord. 01/25/2014
    Rated 5 out of 5★ by Great Car Charger This 12 Volt car charger does a great quick job of charging batteries quickly and has a digital read out that shows how much charge your battery has. I had a battery at 61% and it completely charged it to 100% in about 2 hours. The only draw back is that it is only for 12 volt batteries, but for the price it does a great job, it also tells you the state of condition of your alternator in your vehicle. Best car charger that I have ever owned. 10/21/2013
