Dry Cell Battery?
I'm after a new car battery for my just purchased modified car, but the engine bay is very limited for space..
It currently has fitted a Pulse brand Dry Cell battery measuring roughly 180mm (L) x 80mm (W) x 165mm (H).
Battery world have the Odyssey PC 680 for $335......hhmm
Any ideas for other more cost effective options or other battery sellers guys??
Sounds like a GTR engine bay, some imports come with oil catch cans where the battery sits and limits the battery size.
Try other car battery wholesalers, look at CCA (cold cranking amps) to be sure its got the guts to crank when you need it.
There is a cheap battery wholesaler near my work on Lygon St Brunswick but i cannot remember their name, i normally get good prices there. Maybe lookup in the yellow pages for a battery supplier in Lygon st.
Your other option is to relocate the battery to the boot. (Helps traction on launch )

Yes, thanks for the tip Godzilla, I'll check out some other battery wholesalers, including the one near you.
Yes, not real keen to put the battery in the boot, but it is an option...then I could fit a big lead acid...
The standard engine bay fits a normal battery, but because of the larger intercooler fitted it's now a squeeze.
It's a bit tight in the engine bay at the front near the intercooler...(!)
Heaps simpler than the twin turbos though!
Wow, that is tight.
That battery is tiny, id seriously be looking at a boot conversion to reduce future headaches.
The 'boot' is part of the interior as the Rx7 is 'hatchback' of sorts...
Is it ok to have the battery inside the interior with me?....
I think its ok if you put it in a sealed Battery box and run a breather hose out to under the car.
Not 100% sure though seeing as its a hatch, maybe it needs a little research to be sure.
Something like this;
the boot is the way to go with that setup, whats under the side panels there maybe room under one off them ??

Tagg has a good point with the side panels.
Another idea is how much room under the front guards if you remove the plastic lining?
You could save yourself a long cable run if you have room their.
Thanks guys....Yes really really not keen to have the battery in the 'boot' (car interior)..
I'll have a look into the front inner guards....
Other people have used the small dry cell batteries no probs....it's just the cost and longevity I am worried about. The little battery in it now is partially stuffed...it won't crank quite fast enough to start the car from cold..but once you've been driving for a while the warm start is fine....getting tired of jump starting it though..haha..A lead acid is a cheaper and more simple battery.
The car is a weekend warrior....So I bought an intelligent 900ma always connected charger to keep the battery topped up and ready to go....still no good with the blue Pulse battery..
whoa not sure about it being under the front guards, one i am sure if it would be legal and if you got hit there would be acid going everywhere, there is lots of way you can mount it in the back it depends on how keen and handy you are, see how much clear floor space you have that is clear off componets under the rear floor then you could cut a section out and weld a box in, then place the battery in one of those battery boxes and put that into the new box you made in the floor ???, not a big job if you have some skills ??
Battery acid under the guards or even in the rear compartment shouldn't be a problem in an accident if you use a sealed battery box with a breather tube as mentioned earlier.
The breather tube is needed to let any poisonous/explosive gasses out to under the car, most people just run a rubber hose through a hole in the floor, through a rubber grommet so it wont cut the hose.
Check out some RX7/8 forums, surely someone has done this before and they must have the same issues?

I would be quite happy to run a dry cell small battery....I just have other things to spend $325 on...!! I haven't had a chance to ring any wholesalers or battery shops as yet.....it's not an immediate problem as I don't drive the car everyday.
Well you also need to consider buying a Lead acid battery, a battery box, a few meters of high amperage leads, redoing all the terminals, an isolation switch (in case of an emergency) and your time and the labor needed.
$325 for a smaller battery ATM is the easy whay out in the short run.
Unfortunately life aint cheap, either way your going to pay.

I can say that I have used an oddesy battery in an EB wagon for about 5 years before I killed it by shorting it, my bad. It never gave me any drama's. The whole reason for fitting it in the first place was that I only used the car one weekend out of every fortnight and needed a battery that would just keep working under strange use/disuse patterns. It was expensive but they do seem to work well.

Have a look around for a Gell or AGM battery they don't vent any gases unless there is something seriously wrong.
They are so safe they are recommended on Boats even in the cabin , they can be used upside down or any angle without leakage , no vented battery boxes etc., there is no risks with sparks , flames like normal Lead Acid Batteries as they are charging or fast discharging., they are totally maintenance free so don't even have filler caps, all the hydrogen produced is converted back into water inside the battery.
- Rep Power
A word of warning on Gel batteries.... they are known to split their cases if over charged and will make a mess like any other common battery.
