Battery Charger / Maintainer

Trickle chargers and battery tenders — NOCO Genius, Battery Tender, Schumacher.

18 products in stockSort by Ranked →

A battery charger (or trickle maintainer) keeps a 12V battery topped off when the car sits — daily drivers don't need one, but the weekend convertible, the motorcycle from October to April, or the RV in the side yard absolutely do. Modern smart chargers detect the battery state and float-charge without overcooking it, so you can leave one plugged in for months. Reach for one when a battery's reading below 12.4V on the meter or a stored vehicle won't crank after sitting. Pair with a quick-disconnect SAE pigtail so you're not popping the hood every time.
