Interesting thread. One tends to forget various experiences with batteries over the years. I do remember that Lion and Apollo Batteries used to be marginal. I also patronised a Battery Wholesaler at Silverwater, and his offerings included Century, Excide, I think Bosch and also Yuasa. All cases came from South Korea and he showed me the various labels that they would attach to whatever battery. The batteries were all the same, just the labels differed........
Latterly I have been using Delkor (with very satisfactory results bar one - two year warranty only extended), but Battery World no longer stock them on account of a steep price rise imposed by the Importer. Now, it is Supercharge and Supercharge Gold and, in the past, they have been trouble free. For all that this is worth. Regards. Styria
