Three stages are all you need in a converter

Three-stage charging protects batteries.

WFCO’s automatic three-stage converter handles every charging need for the RV while extending the battery’s life. Well-maintained batteries should never need more than WFCO’s two-stage (Normal and Trickle) charging modes. Our Fast Charge third stage (Bulk) is for the rare times a battery needs extra-power charging.

The WFCO Normal (Absorption) Mode alone is a powerhouse capable of charging a fully-discharged battery in under three hours at 13.6 volts. When the RV is being used, the battery is kept readily charged in Normal Mode.

However, suppose the converter detects no significant variation in the current draw for approximately 44 continuous hours. In that case, our Trickle (Float) Mode automatically kicks in and brings the battery back to full charge. Maintaining complete charging helps prevent stratification of the battery’s fluids, reducing the battery’s charge and longevity.

For those cases when the battery charge drops significantly due to prolonged disuse, poor maintenance, or very heavy system overloads, our 14.4-volt Fast Charge (Bulk) Mode kicks in. Our Fast Charge provides a maximum four-hour charge to prevent battery damage. This full-time feature has been implemented to protect and extend the battery’s life.

The problem with overcharging a battery is that it tends to convert the water molecules into oxygen and hydrogen gasses, which can deplete the water and leave a strong acid solution, possibly damaging the battery. WFCO’s innovative engineering makes Normal and Trickle the only charging modes the RV battery should ever require when adequately maintained.
