Very little is cheaper than Century. Panasonic is one of the higher priced ones, NS60 for example friend friend price (got a friend working in Eneos) is still RM220. But that's for the lower current one. There's a higher current version which is marginally more expensive. Something like RM250 or something.How is the price compared to Century or Yokohama and is it stronger?
Yes, Panasonic 1 size has 2 different power outputs. You probably wanna have a look at those.
Optima Yellows these days brand new sell for 600 and above depending on size. But they last forever. Like minimum 5 years forever. So cost effectiveness is pretty good. But you gotta make sure you're not boiling the battery with your turbo or manifold. Any battery exposed to that much heat will fail prematurely. If you compare your battery with those in the boot like those found in BMW, those with boot batteries last much longer, no heat!
