WF-9845-AD Deck Mount Converter Charger

WF-9845-AD Deck Mount Converter Charger: 45 AMP OUTPUT CURRENT

The WF-9845-AD Converter includes the exclusive, Patent Pending Auto-Detect technology. This microprocessor-driven technology will recognize lithium-ion and lead-acid battery chemistries and adjust the charging profile to match the battery type.

No more buttons. No more switches. An accurately charged battery gives RV owners peace of mind. Eliminating the risk of over and under-charging the WF-9845-AD Deck Mount Converter Charger will maximize your battery life with multi-stage charging and current monitoring in both lead-acid and lithium-ion profiles.

The WF-9845-AD Converter Charger has optimized charging for battery chemistry in the unit. For lead-acid Batteries, WFCO’s automatic three-stage converter handles every charging need for the RV while extending the battery’s life. For lithium-ion Batteries, the multi-stage process ensures a safe operating voltage for all loads, replaces energy in the battery, and assures the lithium-ion cells inside the battery remain balanced.
