Best place for new battery

[deejayem]

Looking for suggestions on best place to get anew battery (and get old one load tested but pretty sure it is dead as looks like 2012 date code). Somewhere near CBD/Northbridge or Osb Park would work well. It is for a Ducati M659 and the old battery is a Yuasa YT12B-BS...not sure if that is an oddball battery or something as I have never replaced one before lol. Any suggesteions as what to replace it with also appreciated :-)
Thanks.

Always had fantastic service/pricing from Batteries WA Malaga.

Ok was going past Challenge today and dropped in. Nice fella, had the battery I needed in stock and gave me a discount just because I asked. Recommended.
