Schumacher Battery Maintainer 1 Amp - Available at

Share on:

What's up, guys? I'm Andy from 1A Auto. Here, I have this battery maintainer by Schumacher—has a nice, long 20-foot cord to plug in the wall.

You can plug this into a vehicle that sits throughout the winter. You can hook these on to the battery. You're going to want to make sure the hood is open when you do that, or you can actually hardwire this in. You just pull the two terminals off the battery and put the nuts back on. We have these quick connects, so you can just plug this in real quick. And then this you could leave attached to a certain vehicle, whether it's a boat or a car.

There is a microprocessor in here, which is going to keep everything safe. So, if the battery starts overcharging, it'll shut down. And also, it's going to detect whether you have a 6-volt battery or a 12-volt battery. Keep your battery fully charged and it'll prolong the life of the battery. Get your battery maintainer at
