The best battery charger for a dead battery is a smart charger with battery restoration modes. These chargers can detect deeply discharged batteries and attempt to revive them using pulse charging technology. The CTEK MXS 5.0 and NOCO Genius 10AU both include this feature.

Final Word: Charge Smart, Stay Ready
Every car owner should have access to some form of battery backup. For some, that's a full-featured smart charger that lives in the garage. For others, it's a glovebox-ready jump starter that kicks into action when they need it most.
