I just read the post from Heath7162 about a problem with a new battery and I thought that everyone might want to know where to get a good bargain from . Century has a small retail shop at their Carole Park Factory in Cobalt Street. You can purchase blemished batteries from here ,that is they have a small mark on the case which does not effect their performance ,only its looks. I have purchased a number of batteries from their with no problems and saved well over 50 % on purchase price from retail outlet.The person who works there is named Chris and is a nice bloke and very helpful. They normally have blemished marine pro,s in stock but check first.
