Expert Answers about Battery Charger


  • Will NOCO Battery Charger Charge Battery Without Damaging It?
  • If the car battery is merely discharged but otherwise in good repair, using a NOCO charger will not damage it. NOCO chargers will not over charge a battery, once full charge is reached, the charger switches to pulse maintenance, which maintains the charge rather than applying full power to the battery. A charger like the NOCO Genius Battery Charger and Maintainer # 329-GENIUS5 would be best suited for a car battery. The charger is suitable for deep-cycle batteries.

  • Does Trailer Battery Need to use Battery Charger
  • You will need to use a battery charger such as the CTEK MULTI US 7002 12-Volt Universal Battery Charger w/ Pulse Maintenance and Backup Power # CTEK56353.

  • Can I Use The NOCO Genius Smart Battery Charger # 329-GENIUS2D With A 64 Ah Battery
  • The NOCO Genius Smart Battery Charger # 329-GENIUS2D is not going to work well with a 64 Ah battery. While technically it will be safe to hook up and use, it will take a very long time for the charger to fully charge your battery. Even for long term maintenance charging, this would not work well. We do recommend upgrading to a different charger like the # 329-GENIUS5, which will work with 12v batteries up to 120 Ah.
