Which battery types should you check?
Match the charger to the battery chemistry and voltage printed on your battery or shown in the vehicle manual. Support for 6V and 12V batteries doesn't mean every mode suits every chemistry.
The 3 NOCO GENIUS models here support lead-acid types such as AGM, gel and flooded, along with LiFePO4. The Schumacher SC1280 supports standard, AGM, gel and deep-cycle batteries, while the CRAFTSMAN CMXCESM258 supports standard, AGM, deep-cycle and 12V LiFePO4.
Check the exact charging mode before connecting a lithium battery. If you aren't sure what battery is installed, confirm its type and voltage before charging.
Is a battery charger or jump starter better in winter?
A battery charger restores or maintains charge, while a jump starter supplies power for a starting attempt. Choose based on whether you need garage maintenance, roadside starting help, or both.
Cold weather can make starting harder, but a charger can't guarantee a start if a battery is damaged or another vehicle system has a fault. Our portable car jump starter guide explains what to look for in a separate emergency device.
Don't charge a frozen battery, and follow the battery and charger instructions for cold-weather use. Read jump starter vs battery charger if you're deciding which tool fits your winter plans.
How do you choose a charger for a car that sits?
Choose a smart charger with a maintenance mode that supports your battery. Follow its instructions for connection, operating conditions and storage.
NOCO says the NOCO GENIUS1, NOCO GENIUS5 and NOCO GENIUS10 monitor batteries during maintenance and can remain connected indefinitely when used as directed. The Schumacher SC1280 and CRAFTSMAN CMXCESM258 also have maintenance functions; follow each model's manual for the correct setup.
A charger cannot reverse every cause of a no-start. For a battery that repeatedly loses charge, have the battery and charging system checked rather than relying on a maintainer alone.
Which car battery charger should you choose?
Choose the NOCO GENIUS5 for a balanced mix of output, battery support and temperature sensing. Pick the NOCO GENIUS1 for compatible smaller batteries and gradual charging, or the NOCO GENIUS10 for 10A output.
Choose the Schumacher SC1280 for 15A charging at 12V and testing functions, or the CRAFTSMAN CMXCESM258 for its display and reverse hook-up protection. Match voltage, chemistry and supported capacity before choosing output.
The best car battery charger for you depends on the battery and the job. If winter roadside starting is the main concern, use our portable jump starter guide to compare a separate tool for that purpose.

Follow the instructions for your exact charger and battery, including the required mode, connection steps and operating conditions.
Can a battery charger jump-start a car?
A battery charger restores charge over time, while a jump starter supplies power for an immediate starting attempt. For roadside starting help, compare a portable jump starter with a charger before choosing gear.
Charging won't repair a failed battery or resolve a fault elsewhere in the vehicle.
Does cold weather affect car battery charging?
Cold weather can affect battery performance and charging, so follow the battery and charger instructions for low temperatures. The NOCO GENIUS models here use an integrated thermal sensor to adjust charging based on ambient temperature.
Temperature sensing doesn't mean a battery is safe to charge; don't charge a frozen battery.
