The NOCO Genius 1 battery charger is compact and easy to use, working with lead-acid (flooded, gel, AGM) and lithium-ion batteries alike — making it a solid fit for both vintage and modern vehicles.
It adjusts charging for temperature and switches to maintenance after charging. Follow the instructions for your battery and check the setup periodically during storage. It is a staple in my winter garage routine.
