These are round terminals I'm afraid, the round to ford adaptors are only £2 each, but shopping around I made one call today and beat this quote down to £145.
The adaptors will no doubt be just what I use, a round post terminal, but instead of putting the cable in the battery post clamp I put a bolt through it and affix the ford terminal/lead to it.
It's a lot of money, but you won't get better for the size.
Most are going for LEISURE batteries these days, as they are semi traction, and deep discharge does no harm, so if left flat for a few months it will do no harm.
