Which WFCO Replacement Converter to Allow Charging of Lithium Battery
Updated 03/04/2026 | Published 02/08/2026
Question:
Battery charger WF66FR. I looks like this one would work for my application but the dimensions list 9.5 wide x 7.25 x 7 tall. Could you verify the 9.5 as it looks very similar to WF58Fr which is only 7.5 x 4 x 4 5/8. Thanks, Charlie

Hey Charlie, the correct part from WFCO to replace your 8955 with one that is Lithium compatible is the part # WF76FR actually. The overall dimensions of this are 9-1/2" wide x 7-1/8" long x 4" tall. This actually auto detects the battery type too so you won't have to worry about switching settings if you switch battery types!
