I brought 3 completely dead batteries back to life. I removed the tips and filled up with distilled water. checked each cell and put on a power pulse charger while charging and left for a few days. WARNING! I charged each battery for about a week and all three Ivs were able to charge them up to 13v which I personally find quite impressive. And if I don't take the battery with me, I put it back in my pickup's battery. nothing hurts to keep up with an expensive investment like my dailies considering a good battery lasts over $100 and I always charge 800cca so they last a little longer. You never know when you're going to need those extra roadside grips, if you ever do, god forbid. But when I'm on top of my cars, those moments are very rare. You will not be disappointed with this product.
