My friend just purchased a Spoon Sports Battery and since the battery post is smaller than regular North American battery posts. Is there any place that sells some kind of adapter or universal battery terminal that will be able to work with smaller Japanese battery posts???

Help !

 

I don't believe an adapter exists.
He may need to get new terminals.
Surely where he bought the battery from (presuming not self imported) should have advised him or be able to sort him out.
