Title: What's the biggest battery.......
Post by: rabbitman on February 08, 2010, 01:36:21 pm
that will fit in a mk1 rabbit?

The one I have now is a supercrank 675cca goin' on 4 year old and it's been good. But this winter I've noticed a definite decrease in cranking speed and at 0F (not plugged in) the battery will sometimes die before it'll start.

I know I want an Interstate, and I want the biggest one that'll fit, I've seen the size 24f is 800cca and another good one is size 34.

Anyone know if one of these will fit under the hood?

Thanks :)

My experiences with Optima have been bad. They have one shot left to earn my trust back.  >:(

I have a 35/75? right now near the stock location on a mk3 battery tray bolted to the frame rail but was looking at putting it behind the passenger seat as well but I think I'm going to put it in a box but that tray looks pretty nice! Then figure the new wiring using the battery cable from an e30 which have a trunk mounted battery and some beefy cable (I think 00?) running into the engine compartment. The cable must be 10' long and can be had for a few dollars at the junkyard plus they usually look brand new because they're covered in carpeting.

My reading suggests that they may be a poor choice for cold climates, despite their CCA ratings.  I've seen a fair amount of chatter about very short lifecycles under winter conditions and the people that seem to love 'em to death often come from the southern parts of the United States.  Perhaps just a coincidence, but no one in the VW club here in northern Alberta will run 'em, for instance.

I've never owned one myself but based on lots of circumstantial evidence I personally stick with conventional chemistry batteries for my winter starting needs... the biggest I can possibly shoehorn into the vehicle.  ;)  

Just one northern Canadian's perspective.

Yup, I've heard some about that, also I've heard of 'em blowing up for no reason too......sorta why I specified Interstate...........

just got my red top.  my weather isn't as nice as gee bee's but, we rarely see it freeze.  the difference between the crappy bimart battery and the red top are night and day.  napa 149.99

My optima never gave me probs in below freezing weather with my 1.9 headed 1.6. always started.

Good cables
clean terminals
good grounds body to engine to batt.

When my car died i had to go start my summer ride so i could get around. Put the optima in the truck cause the trucks batt wouldn't light it off.

Optima for life. She's 2-3 yrs old now

47°F is cold, if you're naked...   :P

Baaaahahahaha, how true. If it's summer time 47F feels chilly but we get only 3-4 months of summerish, then spring and fall take up a good chunk of the year and during that time 40-50F is normal. The rest of the year is winter..............

rabbitman, i would think that living in practically minus temps.. 47f would be gorgeous :P whats that in Celsius?... 50 is 10 I think..

I would love to live in a climate of 10-15C.. anything hotter and you start to sweat.. and thats not fun ;)


I think I read something about New Optima's vs. Old Optima's ... old ones were built with better metals and stuff.. something that makes the new designs inferior.. that's all I know lol

The problem with that, Vince, is I live in the SouthEastern US. We're in "deep winter" right now and the temps are barely in the negative C range (-5 and warmer) in the dead of night.

I had one that died right off the bat: two months' service. The replacement managed to make it a year, then quit holding a charge.

EVERSTART MAXX FTW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(http://flashoffroad.com/electrical/Batteries/image/DSC00440.jpg)

I have had one in my off road bronco for about 7 years. Get the 34/78 group if you can as I always use that battery as my backup for every vehicle I have. 3 year warrenty and usually the Wal-Marts around here will take anything if you have a receipt no questions asked if you have a problem. And if everything is junk no way to get a replacement your only out about 70.00 for a new 1,000 CA   800 CCA battery.

they call them Ever Start, because they aren't good enough to call them Always Start... when they leave you stranded (because they are a brand no body has ever heard of.. ;) ) you ask.. do they Ever Start. lmao

$79 is a good price even if you only get 3 years out of it. your lucky to get that out of a high price one anyhow..

I will  relocating the battery to behind the passenger seat, I will have to have some custom cables made, I search several websites, and it seems most of the shops also do welding cables also
Going with side mount post on the Optima

I paid like $45 for the supercrank I have now, it's going on 4 years and I can tell on a cold day that it's seen better days.

Will size 34 fit? Or too tall?

Post by: theman53 on February 09, 2010, 07:30:06 pm
The only issues I have with the EVERSTART MAXX is the stock cable length, but on the last rabbit I went to 1/0 and longer...no issues.

I don't have any personal experience with this, but I've heard Odyssey batteries are excellent.  I have a diesel-nut friend who methodically researches every aspect of every component, and he says they're the best.  I believe that they're rebranded as "Diehard Platinum" as well?  They're considered a dry cell battery because of their construction, and can be mounted in practically any orientation.  They have excellent CCA, cold weather, and deep cycle capacity.  There's a datasheet somewhere on the internet for them if you want the details.  Anyway, this is just something I heard.  I plan on using one in my Audi when the time comes.

my brother works for a big battery company. he says that lithium batteries are good, but the recycling part is the real killer. apparently theres a lead acid battery in the works to compete with lithium. the battery contains a multiple of capacitors to lessen the stress on the battery. lithium batteries have no problems with high spike loads, but lead acid do.

i bet with a big 1 farad cap (install a toggle switch and a gauge so you know when its topped off) it would be a piece of cake starting in real cold. the cap could charge up while the glow plugs do their thing too...

then you don't need such huge batteries, although they are a good idea..!

Well I just bought a size 41 interstate, 650cca. I wanted bigger but I couldn't find a size 34 with the terminals on the right side. I was getting desparate, 20F here lately so I don't plug in and it still cranks slow, 0F is supposed to be pretty easy.

I have a hugge battery in mine :P

(http://i299.photobucket.com/albums/mm307/J_holubek/Diesel/1204091501b.jpg)

It used to start a 6.9 IH, so I figured it was good for my 1.6 ;) No clue on the CCA though :( but it doesn't fit properly, as can be told by the zip ties holding it in (temporary) lol
