Hey everyone,Its time to replace my battery on the old E30. Now, since I've never had this replaced on the bimmer, I'm asking the forum for some help in sourcing one.Firstly, how much does a dry cell battery cost? What model or type doe a jetronic E30 use?I've been getting quotes but they are several hundred ringgit each.Now, should I go with the dry cell (maintenance free) battery or stick with the current 'wet-cell' battery?Thanks.
