Review on Mroinge Smart Car Battery Charger And Maintainer - 2A/5A 6V/12V Fully Automatic Trickle Charger And Desulfator For Lead Acid And Lithium Batteries With LCD Display by Joshua Vogel

I originally bought this charger after I had restored and upgraded an old Power Wheels car with a LiFePO4 battery. I have since used this to bring a dead truck battery back to life enough to get it started and to an auto parts store, topping off a lawn mower & four wheeler, and a couple of other battery powered toys. It has worked flawlessly in all charge modes. The screen displays all relevant info in an any easy to understand manner, and switching modes is also simple & intuitive.If you have miscellaneous 6/12V batteries that need occasionally topped off, or regularly recharged, then I highly recommend this product for you!All that said, this is not powerful enough to boost a totally depleted battery, nor would I expect it to be. They also don't advertise it for that purpose. For that you'd need a much more powerful charger with a boost mode or a specialized jump starter.
