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.

  • Installing BCDC Battery Charger And Maintenance Charger On Second Battery
  • You can use a maintenance charger like # CTEK56353 or similar when using the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D. The Redarc charger is designed to keep your battery at 100% capacity for about 10 days, after that a maintenance charger would be necessary. I do not recommend putting an independent maintenance charger on the second battery during this 10 days, as it could cause overcharging or overheating if you do not use the pass through.

  • 6 Volt Battery Charger
  • That's a great question. You can use a 1 amp charger to charge a 6 volt battery, however the charger # CTEK56158 is for 12 Volt batteries.

  • Battery Charger Recommendation for a 16 Volt Racecar Battery without Alternator
  • Sounds like your race car doesn't have an alternator and you need a charger like the # CTEK56830 to keep your battery strong between rounds. This charger would put 5 amps to your battery. 5 amps wouldn't be considered a quick charge by any means. But if your battery does a good job holding a charge and you have a decent enough amount of time between rounds the charger should work. Using a lower amp charger will help allow the battery to stay strong for a longer period of time as opposed...
