Through the years, I have personally turned to NOCO’s products for their quality and reliability and the GENIUS10 is my preferred car battery charger and maintainer. Our top pick comes from the same company that makes our best portable jump starter. Top pick: NOCO GENIUS10 fully automatic smart charger/maintainer You simply never know when your car’s battery needs a charge, and we especially recommend one if you often store your car for winter. Those are the products we’ll be focusing on in this article, and we recommend every car owner to have one in their garage. Nowadays, advancements in technology have allowed the functionalities of a car battery charger and a car battery maintainer to be combined into one convenient, portable product. Battery maintainers are best used when a vehicle is being parked for a long period of time and you don’t want the battery to die. A car battery maintainer is what you would then use to make sure your car’s battery stays topped off over time, providing a charge only when voltage has dropped. Once it did its job, you would have to disconnect it because it served no other purpose. Battery chargers were designed to do just that: charge your car’s battery. There was a time when car battery chargers and car battery maintainers were two separate products. As a result, it has become difficult to pick out the good brands from the bad, and you don’t want a bad product being hooked up to your car’s battery. As expected, the market saw a huge jump in not only sales of portable jump starters, car battery chargers, and car battery maintainers, but also the number of companies manufacturing and selling those products. After not driving their vehicles for a few weeks or longer, they realized their car’s battery was dead and they had no easy way to get it going again. The pandemic lockdown of 2020 was a rude awakening for some car owners who didn’t have a portable jump starter or car battery charger in their garage.
