Old article, quite battered (7)
I believe the answer is:
antique
'old' is the definition.
(similar in meaning)
'article quite battered' is the wordplay.
'article' becomes 'an' (English indefinite article).
'battered' is an anagram indicator.
'quite' anagrammed gives 'tique'.
'an'+'tique'='ANTIQUE'
(Other definitions for antique that I've seen before include "of great age" , "Object that has acquired value with age" , "Valuable due to age, like some furniture" , "Age-old" , "from long ago" .)
