This charger is a must-have for anyone who needs to keep their batteries charged and maintained .Through trial and error, I found that this charger can be used on a variety of vehicles and batteries, including ATVs, boats, and lawnmowers. The charging and desulfating process is efficient and effective ensuring that the battery stays in good condition for longer. The only downside is that it may take a bit longer to fully charge larger batteries. Overall, a great investment for anyone who wants to keep their batteries in top-notch condition..
