OK, I want to get a dry cell battery (due to relocation to boot to free up room in engine bay- I know you don't need to go dry cell if you box a wet cell, but I like the advantages of small size and less weight). The thing stopping me is the cost- they are very expensive here in Australia for the three brands I've researched; Odyssey, Buddy Club and Braille Auto. $260 was the cheapest and the cost went north very quickly from there ($400+).
The fact of the matter is it's very worthwhile now to purchase one from the US given the current exchange rate (96USc for AUD$1 or thereabouts). Typical cost savings are between $100 and $200 (give or take for freight).
I'm definitely going to buy a dry-cell battery for my Silvia, and it will almost definitely come from the States. I'm putting this up to give others an opportunity to express interest in purchasing one, too. It's up for discussion because people will have different needs- power, size, weight, cost, and other concerns. The only possible problem is getting a lot of batteries through customs. I'm currently in talks with a mate who works in customs to see if it is indeed cause for concern.
I haven't gone so far as getting even rough quotes for freight because if nobody shows an interest I don't need to worry about it for many, just my one. If there is interest, I can get rough quotes and potentially lower purchase prices as well.
Be that as it may I've come up with a shortlist of batteries I am considering to suit these priorities- decent PCA and CCA outputs, weight and cost (because I'm cheap).
The links have more detailed info on actual dimensions, PCA outputs, and amp hour (Ah) ratings but I'll list what I think is important.
Braille B14115 Battery

All the information I could gather...
22Ah
600CCA (reportedly, I'm skeptical of this)

Odyssey PC925 Battery
380CCA
24lbs/10.9kg

Stinger Car Audio also do dry-cells but my interest was waning when I got to them.
The last issue is what legs we have to stand on if they fail or have problems. Warranty is something I'll have to look into. If it's a huge concern I can move the focus from the US and get as good a price as possible from an Australian dealer, but I can almost guarantee the savings will be very minimal.
So yeah. Currently my Silvia is off the road (literally) until I get my new jack, but I'd like to sort out this battery stuff while it's doing nothing. I'll let this run for a week or two and see if there are people interested.
By the way, the batteries I've listed should be sufficient to kick over an RB25-DET, but there is no massive audio- just a deck and splits, and an alarm with a few bells and whistles.
Cheers folks.
