Review: Best charger out there - As a heavy diesel mechanic I have used many different chargers over the years. I was originally brought into this product but a coworker but was skeptical at first. But I will have to say that this charger is a game changer! It can and will bring a battery that’s been sitting for over a year back to life with little to no effort. I have had battery’s that had under 2 volts come back to life and continue being used. The charger will also tell you if the battery has bad cell and won’t take a charge so you don’t need to waste time trying to figure out the situation. If you need a multifunction charger I highly recommend this one.
Review: These are the best chargers I've found so far for AGM batteries - These are the best chargers I've found so far for AGM batteries. I have two large AGM Lifeline batteries for my RV and placed two of these chargers (one each battery) to maintain the batteries indefinitely. They have work well so far both charging the batteries and maintaining them. Highly recommended.
