Optima Battery Question?
 

Anyone got an Optima battery in the RX8?
I was told by a battery shop that it could not fit without changing the lead arrangement and I am sure I have seen an RX8 with one since then.I want to get a dry cell battery as my battery keeps leaking when i corner hard.

I have the Optima Yellow Top D51R ...R being for right hand drive cars Part number 8073-167 Fits perfectly , great strong battery no need to change any terminal wires they probably quoted you on the D5 1L for left hand drive .

Thanks,that would explain it..I'll try getting one this week.

I think I answered this in .com.au. As Michael said you need the R model but I haven't found anyone that stocks them, they have to be special ordered. Also they are Very heavy.

Are they heavier than a stock battery? Do you have one?

I have the D35 (650CCA) and it weighs roughly 17kg. The D51R is only 450CCA and weighs 12kg.

The original OEM battery weighed 9.5kg and the replacement one 16.8kg. https://www.rx8club.com/rx-8-racing-25/weight-stock-rx8-parts-81791/

Why did the replacement weigh so much more?

Because it went from a 400 odd CCA battery to a 650 to help with flooding and cold start issues.

:lol: Knowing Matt's 'weight issues', I can almost hear the dismay in his voice on this one...:lol2: :lol2:

Yeah its kin dof why I pointed it out. Even sticking with the 450CCA you add 3kg.

Well there goes that idea.You are right Dave,back to square one! I might look at that other brand that starts with O,can't think of it right now or those Pulse batteries??

Odyssey. But it wont help either. You either have to be carefull with cold starts, flooding etc and go for a lower CCA battery. Or suck it up and go with the heavier battery. Remembering that the battery is mainly for starting (exception is running accessories when the car isnt running). Once its running its the alternator that does all the work.

i have a yellow top 35. awesome, no lead changes, cranks like a motha.
