I have to disagree with you both on this one. If you let an engine sit, piston or rotary, the oil drains from the pistions/rotars and then the metal from the pistons/rotars will sieze to the walls. Once the rust starts, you are screwed. Not to mention, if you use the vehicle as a DD, then the engine and car parts are use to being "exercised" everyday. So when you abruptly let them sit, things rust, dryrot, and go to sh*t. If you do not use the vehicle as a DD, then you can let the car sit for longer periods of time since it is not use to the constant "exercising".

funny, just got my optima red top this weekend. lots of confusion on the model number of the battery. costco one is a 75/35 but the terminals are on the wrong side. got mine from a battery store, model number is blank but the part number i think says SC35A. size 35 with the posts on the correct position. no extensions needed.

Yea watch out for that, Costco has a different battery all together lol. You used the attachment though right? The thing that raises it up a bit?

My two cents on the "exercising"? Not being cruel. Well prepped a car can sit indefinitely. With no prep, 1 or 2 years is not all that bad. I let my car sit for 10 months last year. I expected and had no issues on startup. It was as if I shut it down the night before.
Anyway.
What is the best red-top for a trunk relocation? I was going to go with an Odyssey PC680, but changed my mind as my car sits for weeks at a time.
Opinions welcome, but actual experience is prefered.

Regarding the seizing of iron rotors in aluminum housings, I was just reading Wikipedia and came across this; "This ensures that even a severely overheated Wankel engine cannot seize, as would likely occur in an overheated piston engine."
So the yellow top offers no other advantages to a standard battery other than deep cycling?

I like the optima's because of the spill proof and strength they have. With the experiance I had with them so far I'll more then likely keep buying them for all my vehicles. Hell my old vehicle had one, and well, I kinda drop it down my hill, and was like ohhh sh$t there goes my $, and got it and the case was fine just a few scuffs nothing major, and put it in the car and fired right up, and to this day it's still working (3-4years later).
I went with the red #34 since it has 800cca, 1000ca, 100min reserve capacity for in my trunk.

yep, i did. only one of it tho. i think the B plate. but the stock battery that i took out in mine also used a raising plate and it's not size 35 (a bit smaller than what i bought so that was a surprise) so i don't know if that was really stock or the previous owner got scammed

Battery preferences?
Ok guys, so its time for me to replace my battery in my '04 rx8 - anyone have any particular batteries they prefer, or know to have a good track record? kind of a dumb question, but still worth asking i think.

It gets pretty cold in Connecticut, right?
if so, cranking power is what you need. Most batteries will do a good enough job but if you want a maintenance free batery, you can look into an Optima Red Top

yeah it does get cold in the winter - i was looking at the optima, a friend of mine who is really into all things mechanical (read: builds extreme off road vehicles) uses an optima in his jeep. thanks!

Both the Optima Red and Yellow top batteries purport to have better shock and vibration resiliancy than standard batteries due to their method of cell contruction and isolation.
As far as the Yellow top, yes, its advantage is better recovery from deep cycling.

Until about 2-3 weeks ago. I took it out and put it into my 7, it worked that time, so I shut it off, and I left it in the car connected.
yesterday, I tried to start it, it wont even crank, took the battery to Autozone, its too low they wont even charge it for me.
so I was like **** it, I put it back to the 7, jump start it, let it run for hmm 15-30 minutes, then it start right up. it works I guess this is the good thing about deep cycle batteries huh ? (to be safe, Im going to buy a battery charger)
So yeah Optima is good

I got 4 years out of my Yellow-Top, and it performed well during that period, including a flood recovery and the de-carbon procedure. However I would have hoped for more longevity.
Based on the negative reviews, I decided to change to a Hawker Oddyssey. These get high ratings from the DIY electric vehicle community.
Fortunately, this battery is available through Sears, re-branded as the DieHard Platinum-Plus P5, group 35. It's a heck of a battery, more capacity and deep-cycle ability. It's an AGM type battery like Optima, so has the same leakproof and non-corrosion advantages. And the Sears warranty puts the Optima Yellow-Top warranty to complete shame. But, do not buy if you are looking to save weight.

Yes, I have read too many reports of Optima (specifically their deep-cycle versions) having lackluster quality control since they were bought out by Johnson Controls.

So what I gather is that the deep cycling actually could provide benefits to me for decarbs, and deflooding, or if I leave the trunk partially open by accident.
What does Sears charge for the DieHard Platinum-Plus P5, group 35? What are it's CA/CCA ratings? Thannks.
