When I replace ours - WF-9865 65 Amp Power Converter
Automatic three-stage battery charging maintains your battery’s life with three nominal voltage output modes: 13.2 Vdc “float” mode, 13.6 Vdc “absorption” mode, and a 14.4 Vdc “bulk” charge mode. Electronic current limiting automatically shuts down the power during overload or short-circuit conditions.
