Other findings
- Bulk charge voltage
- 14.4 V in bulk, entered only from a discharged battery
- Bulk mode duration
- Bulk ends at about 5 A of draw
- Charging stages
- Three stages — Bulk, Absorption, Float
- Model numbers in series
- WF-8712P, 8725P, 8735P and 8740P
- Nominal output voltage
- 13.6 V nominal — the mode it holds in normal use
- Output voltage verification
- 13.6 V ±0.2 with no load means it is working
“If the output current reaches its maximum (normally caused by a discharged battery), this will cause the converter to go into Bulk Mode, which means the target output voltage will change to 14.4 VDC and a timer will start.”

“Bulk Mode will be maintained until the current draw drops to approximately five Amps, or until the timer reaches four hours (whichever happens first).”

“The 3-Stage “smart” charger continuously measures the battery voltage output and regulates the amount of charge using three modes of operation; Absorption, Bulk and Float modes.”

Vehicles the manufacturer names for this charger
- Forest River Prime Time AvengerManufacturer documentedView platform: Forest River Prime Time Avenger →
Forest River publish this converter's manual in the 2026 Avenger's own Electrical component list. They list THREE converters for the model — the WF-8700-AD, the WF-9500-AD and the WF-9500LiS — and do not say which floorplan or option package carries which, so this names what the maker documents for the model and not what is in any particular trailer. Read the part number off the front panel label of your own unit.
