Right,, never use acid core or soldering acid for electrical connections, it will corrode the wire.

For battery cables, you may have better results if you buy a tin of solder paste that you can dip the copper into prior to applying heat. You will find the solder flows quite a bit better than just trying to heat and apply the solder to the bare copper.

Yep, stick the terminal in a vice, get a roll of thick rosin core, heat the terminal just enough to melt the solder, if the cable fits the terminal properly fill it about half way, stick the cable in ad add heat until the solder wicks up the cable..add heat shrink if you feel the need...it will probably last a lifetime...and no more wing nuts on batteries, replaced a 6a a while back on a buddies boat over a loose wing nut.
