Maintainer & Charger Picks

Our picks for smart chargers and maintainers that keep a parked car healthy, from daily drivers to cars stored for the winter.

Chargers matched to what you own: motorcycles, diesel pickups, boats with onboard chargers and garages full of batteries.

How many amps you need, 10 amp chargers, and what changes for lithium, AGM and 6V or 24V batteries.

Hooking up a maintainer, charging a dead battery, trickle and float charging, safe habits and getting a car ready for storage.

NOCO, Schumacher, Battery Tender and other brands, compared head to head and reviewed one model at a time.
