南非采购需求：摩托车电池、电动自行车电池、汽车电池、蓄电池、锂电池

I'm in the market for a 6V battery suitable for a vintage car. Specifically, I'm looking for something with a capacity between 60 and 100 Ah and the ability to deliver high cranking amperage, ideally in the hundreds. Can you provide recommendations on where to purchase this type of battery? Any info on suppliers or availability would be greatly appreciated. Thanks!
