Is there any reason that I shouldn't tin my plain copper lugs with a lead-free solder, at least just on their contact surfaces where they'll be clamped? I can't easily buy tinned copper lugs locally (even the West Marine here doesn't have them!), but I can buy decent-quality plain-copper lugs at several places here. I'm thinking that I could cover the top and bottom of their contact area with a lead-free solder before I crimp them on the cables. Does this solder oxidize appreciably? They won't be used on a boat or in a marine environment, and my FLA batteries are in a well-ventilated compartment to minimize acid fumes. After I've crimped them on (I've ordered an FTZ 94284 crimper which will be here next week - yeah!), I'll use some thick adhesive heatshrink on each lug.
Has anyone here done this to their lugs?
