I have been using this battery tender on my boat for quite some time. My batteries always stay fully charged thanks to it. The tender maintains the batteries even through the cold winter. Come spring time i'm confident in taking my boat out onto the water again. Additionally I have never worried about overcharging the batteries because this tender has built in safeguards against it. It's been a solid purchase and I would recommend it for Boats, lawn equipment and anything else Having a 12 volt battery system.

I have 6 of these for my 6 cars which I use when I travel. They just work great. No more dead batteries when I return home

This 4 AMP battery charger works great! It’s super easy to use. You really don’t need the instructions for the most part. It’s a very good value for the money.

Perfect size for our use. Cold weather we need to make sure vehicles are good to go. Medium price for unit. Easy to use. Can read it without glasses

Years ago I bought a simple battery charger made by Dellran. I was impressed with the quality so I bought this more advanced model. And I wasn't disappointed. This is a quality charger. Materials and design are first class. I own several machines that need battery maintenance. Proper battery care will extend battery life. The replacement cost for new batteries is expensive and increasing. And that's good reason to buy this charger.
