SKU CH-0366-C988G

A 6 A single-bank charger for 12 V batteries, approved for wet-cell and AGM types with waterproof construction and automatic maintenance mode

  • Charges 12V batteries at 6 amps
  • Universal 100-240 VAC input works worldwide
  • Approved for wet cell and AGM batteries
  • Waterproof construction suits fresh and salt water
  • Automatic maintenance mode protects battery health

Everyday 12 V battery charger

The Dual Pro RS1 delivers a 6 A charge to a single 12 V battery bank. It suits boat owners, ATV riders and golf-cart users who need a simple, affordable way to keep lead-acid or AGM batteries topped up between outings.

Universal input and maintenance mode

The unit accepts 100 to 240 VAC at 50 or 60 Hz, so it works on household or marina power worldwide. Once connected it runs fully automatic, switching to a maintenance phase that prevents over-charge without user intervention.

Waterproof construction with short leads

A rugged, waterproof case handles fresh- and salt-water spray, and independent outputs mean each bank is managed separately. The supplied DC cables are 5 ft long, so the charger must be mounted close to the battery compartment.

Questions about this item

How do I install the Dual Pro RS1 6A 1-Bank 12V charger and what step is often missed?

Connect the DC charge cables to the battery terminals — positive to positive, negative to negative — then plug the AC cord into a 100-240 VAC 50/60HZ outlet; the step people miss is verifying the battery type selector matches Wet Cell or AGM before powering on.

What maintenance or replacement will the Dual Pro RS1 6A charger need later?

The charger itself is maintenance-free; its two-year warranty covers defects, while the connected batteries will eventually need replacement as their capacity fades with normal charge cycles.

What limit appears first on the Dual Pro RS1 6A charger during sustained use?

The 6A output current is the limiting factor — a deeply discharged high-capacity battery will simply take longer to reach full charge because the charger cannot deliver more than 6A.
