What's a good SMALL battery with limited space?

I've been running this dry-cell for 6 years without a problem, 800 CCA on a blown smallblock. They were called 'Black Panther' when I bought it but I believe they are Odyssey now..

CC

 

I'm using one of these in my pickup, it cranks the flatty over real good.

 

My choice would be a RG-35A or RG-35AXC Concorde Aircraft Battery
No maint., no vent needed, & no spill...
5"wide X 6" tall X 9.6"long
Enough umph to start a 520 CI six cylinder engine...

i use 2 sealed harley/buell x1 lighting batteries on a 13 to 1 526 ci big block chevy with no problems they are tinny 3" wide 5" tall 6.75" long

 

I've been running the Odyssey PC680 up under the dash in my A (SBC) for four years now and it's never been anything but reliable. I've cranked the hell outta mine and was surprised that it didn't go flat.

The Dynabatt is a private-labeled Odyssey that until recently was $155.00, and that's the reason I bought my Odyssey from Portable Power for about $105.00.
But, you're in luck..........according to Dynabatt's website they're selling them for $99.00 now. DEAL!

If you go with the Civic battery, remember to place or vent it outside.

 

If space is tight for a normal size battery, why not run two of the smaller bike batteries in parallel?
CCA will be doubled and probably be close to the smaller normal size car battery.

I thought of doing that on the 31 for a while, there's a couple of nice out of the way spots on either side of the seat in the trunk area.

Ended up making a battery box that mounts in front of the rear axle, inside the frame, under the floor.

Did that in the 32 and it works well, but can be a bit of a h***le getting it down.

Plans are to cut an access hatch in the 31's forward drop-down trunk area so the battery can be accessed from the top.


No matter what you do, there'll be a day when you need all the CCA you can muster.
(Cold Cranking Amps.)


A good ignition helps as well.

Did y'all know that an engine at a dead stop can be lit off with an MSD amplifier box under some cir***stances?

 

Odyssey dry cells. One in the roadster,one in the harley. I likey.

 

I have run a Garden tractor battery on my Quad 4 project and Ford 3.0 L V6 project for years without a problem. As long as you dont have a lot of loads and the Starting System is in good shape, The Garden Tractor battery will hold up fine.

 

Yep, Dynabatt, 13 lb's, prices have come way down since the first one I bought.

 

There's a thread on here somewhere showing an Odyssey mounted to the inside of the firewall on a swingout frame.......

 

I'm going to be running the odyssey pc625 in my off topic four banger, i've done my research and this is a hell of a battery, remember when they list CCA, they test theirs at 0 degrees, most battery manufacturers test at 32 degrees which is the standard, so they actually produce a lot more CCA then what they might indicate compared to a standard liquid battery. they have a lot of other advantages too. There's a lot of battery crammed into that small package, f you want to know how good these are, they had approved one for a Cessna airplane last time I checked, It takes a lot to make it past the FAA certification process, I believe the original use of these batteries was in military uses.

 

The Odessey batteries are very fussy about charging. Had one in my trike and it died when I charged it with a normal battery charger instead of the special one - expensive mistake. Since then I've used a regular lead acid battery from an Electraglide and it's been all round better.

I'd suggest a regular battery from a Smart Car.

 

right, they give a list of proper chargers,there are a bunch of approved ones, if you use a charger that produces too much voltage, it will cause the safety vent to open, battery outg***es and it's no good. If you have the right charger they are a tough battery.

 

I ended up with a Miata battery. Not as small as the Odyssey, but you can buy them anywhere and around $95.

 

I've had an Odyssey in my V-8 bike for over a year. It has sat idle for the past 4-6 weeks. I needed to move it and it fired right up.
Battery Mart has the best prices and they ship for FREEEEEE!!!!

I don't understand about the special Odyssey chargers. They list four (4) different models; (6amp, 12amp, 25amp and 40 amp) which range in price from $73.00 - $320.00. Each charger says it's recommended for the PC680 (which I have).

Last spring after building a new motor, I put my old 6amp charger on it for the night just to make sure it had full cranking power. Although I wasn't aware of special Odyssey chargers until viewing this thread, I don't think I caused the battery any harm.

So I guess my question is; "Can I continue to use my 6amp charger if necessary, or do I need to stimulate the economy a bit?"

 

I had seen more then four listed, I'm looking for it, they had an entire list of chargers that were safe. it's all about voltage, don't quote me but I think it can't produce above 15 volts under full charge or something like that.

 

here's some tech info, shows the float charge voltage and the cycle charge voltage. I'm watching for a used charger for an airplane battery, they are voltage controlled also. pretty much the same thing. http://www.odysseybatteriesonline.co.uk/odyssey/other/techinfo.php

it's kind of hard to find here's the direct link to the pdf with the chargers http://www.odysseyfactory.com/do***ents/ODYSSEYApproved12VChargers_000.pdf

 

I have an old Schumacher that only produces 2 and 6 amps. I guess since it didn't do any harm before, it's O.K. to use. Here's hoping.

 

on this subject how many amps can a standard 12 volt lantern battery produce? an alkaline like a duracell brand? going to install one as a backup for the door lock system, so if the main battery fails,i can still get in the car. no external locks, easy to do with a hidden pig tail taped off and a relay. I just need to know the current so i can fuse it properly

 

Sure glad yall started this thread! I'm building an "A" roadster with SBC. Bought a batt. box from Speedway, but it's big and gawky and will use up way too much trunk space!
All these mentions of the Odyssey #680 have about convinced me that little bitty battery just might be the ticket, no sealed and vented box needed, and if I build a box the right way, I can mount it above the wheel well, out side the vertical brace that runs from floor up to the lip for trunk lid, where it will be tucked up under the upper curve of the quarter panel out of the way and completely off the trunk floor.
Just another example of how great this forum is and why I don't mind paying annually for an Alliance membership.

I used a Honda car battery for a crx or something in my /6 rail. I choose it becaue it was small , (narrow ) and had good cranking capacity. After two years i am still happy with my choice.

well the new types of batteries coming out will put an end to the old dinosaur batteries, thats one traditional thing I won't miss, acid leaks,eaten up battery trays, corroded terminals, out g***ing flammable gas, battery being ruined from going dead a few times, frozen cases, sometimes exploding, The newer ones solve all of these problems in a smaller size and a lot lighter too.

 

Do you mean like the Oddesy, or one of the new exotics?

If it's one of the exotics, do you know of one that's on the market?

 

I used a Miata battery in my RPU. Under the dash, it fit fine.

Has anyone used an XS from PowerMaster? I like to shop locally.

like the odyssey, some oem manufacturers are using them now, as well as police cars. the particular style of dry cell has a lot of advantages, there is more then one manufacturer making this style. the idea is to keep the electrolyte trapped in a gl*** matt instead of sloshing around. they also have other features that allow them to pack a lot of battery in a small case. These batteries come in more then the tiny size, you can get them up to a pretty big size, just have a lot more kick then a standard battery.

 

Go with an Odyssey. You'll like it. I put one in my Harley and was so impressed I put one in my T roadster. Great battery, and they don't self-discharge in storage.
