Keeping your car’s battery in good health is extremely important. Not only does it save you money in the long run from not having to prematurely replace your battery, you won’t have to deal with the inconvenience of your battery unexpectedly dying. At first glance, battery maintainers may appear to be the same thing as a battery charger, but they serve a different purpose.
Also known as float chargers, the job of a battery maintainer is to keep your car’s battery in good health if it isn’t being used for a long period of time. So if you plan on having your car sit in the garage for months, you’ll want to invest into a good quality battery maintainer.
We’ll jump straight into our list of the top 10 best battery maintainers, but if you want more information on battery maintainers and why they’re different than battery/trickle chargers, refer to our table of contents.
