I'm just curious if anyone has any personal experience using Optima Batteries (http://www.optimabatteries.com/publish/optima/americas0/en/config/product_info/automotive/starter/technical_specs.html) under their bug's rear seat ... and if so , what 'model' are you using (ie. what the heck is the difference between a group 75/25 and a group 34/78, other than physical size and some more power/capacity). I have a converted 12v '66 that I am considering putting one into, that historically took a group 42 battery.
thanks in advance,
Craig

I use a red top in my F150 - it can sit for months and it will fire right up - great battery for the money, and a pretty good warrenty too.
-
I put one in Rick's car. I believe it was the group 75 one. The best deal seems to be the place on Bridgeport in Richmond. It was exactly $150 with the tax, tax, and tax.
Of course it will crank well, it is much bigger than a group 42 Beetle size battery. And it is much heavier.

I have an optima Red in my truck. It has made its way from my old 63 for a few years, to my brothers 3/4 ton and back to my truck. This battery has given me zero problems. I bought mine at a local dealer here in Campbell River, but one day i was in Walmart they had the red and blue series for about 100 -129 bucks. The thing i like about them is they are sealed can be mounted upright or on their side, have great vibration resistance and a hell of a lot of cold cranking amps even after sitting for months. I will be buying a brand new one for my new project when its time.

I'd just recommend using a 75DT from interstate (DT-dual terminal universal battery) or another favourite is a DELCO brand.
It should easily last 5 years without any issues and its aprox 100bucks. My shop has sold hundreds of Interstate batteries and NO comebacks. After 5 years I usually sell a new battery to majority of my customers or I'll start seeing internal shorts sometimes regardless of battery make.
The Optima will weigh more and as far as life is concerned I have not seen them to pass a load test any longer than a traditional lead/acid battery.
A beetle doesn't require alot of CCA's so I'd just go with a 75DT.
Just remember alot of people \"THINK\" a batter is good just because the car starts well. I do load test on batteries with either my little MINI VAT SnapOn battery tester or my traditional bulky VAT40. A battery can fail the load test and it'll cycle the alternator on more often which is a BAD thing. If you have a loose battery terminal the charging system will go full tilt!!! I melted my brand new alternator just because of a loose terminal in my 65.

yeah alan !! LOL !!!!!! how about the lightest battery ?

So what batter is best for starting your car? Pancake or Waffle?
-

The Odyssey PC 680 is hands down the winner. At only 16lbs, it is around half the weight of a standard Beetle battery. If your car is only a summer driver, this battery will work for you.
-
Anybody know where this Odyssey PC 680 is available from?
-
The best deal bar-none is eBay. There are always several guys selling them drop-shipped directly from Odyssey. Do not get the one with the metal jacket, but do get it with automotive posts.
I remember doing the calculation a year and a half ago. You can buy the battery, have it shipped to Pt Roberts, pay the taxes, and get change from a hun. The stupid local distributor doesn't even stock the automotive posts, and for that will charge you an extra 30% on the battery. You will have to fab your own strap, the stock one is too long.
-
thanks for everyone's replies and insights ... car is (will be, once everything is finished) a daily driver so unfortunatley the Odyssey is not a viable option ... the current battery that is in there from the p.o has some post and connection corrosion, and one of the older ones leaked as well, my understanding with the Optima's is that this wouldn't be the case, hence my leaning in that direction - otherwise I would be more than happy not to have to pay $150 for a battery.
Alan, thanks for the heads-up about the loose connection issue, I'll make sure to double check that as well.
Cheers, Craig

Hey guys, can someone explain to me why the Odyssey battery is not for a car that is daily driven? Also, why do you not want the jacket on the Odysey battery? Thanx, Brian. Sorry for the dumb questions but I was looking at them on E-bay.

Didn't he say :huh:

A nice plus about the optima is everywhere that sells it must warrenty it for seven years! A nice plus driving across the country! Full warrenty! No pro-ratings. just exchange!
-
1976bus, Costco has a nice batter for you. Just add water and it'll make great pancakes ^_^ LOL
the PC680 is a light motorcycle battery. The wierd thing is I dont know how to test them. I've never tried testing my PC680 with a Snapon MiniVAT. I've never even seen a battery testing procedure for motorcycle batteries. Maybe I'll do some research. They do say they have a lifespan of 10yrs. I doubt it though.
A friend of mine has been using his PC680 in his SVO mustang for 2 years now. Its a 4cylinder turbo ford that gets driven virtually all year round. He's had zero problem using that motorcycle battery in his car.
The PC680 with metal jacket is what I bought. Thats the only one the supplier had in stock. Its removeable so its not a big deal but it did cost minimally more than a NON metal jacket. Who cares just make more HP out of your flat 4 ;) that'll make up for extra weight.
For a \"regular\" guy thats not concerned of saving weight in a hotstreet Vdub I'd just use a regular lead acid battery. If your worried about corrosion you should be spraying the anti corrosion paint specifically for batteries.
Interstate has a good warranty that should be good across the country aswell. I'm not anti - optima. I just see them lasting NO longer than an Interstate lead/acid. And IF THEY DO last longer why gamble having a battery that may compromise the life of your regulator in your alternator or regulator of the generator. You should change your battery after 4-5 year regardless. There are things to be cheap on in life. A battery is not one of them or you'll end up hitchhiking or be screwed and on a sunday night after dinner you'll have a dead battery and resort to buying a piece of crap Canadian Tire battery.

How right you are Alan. Jenn and I had to push start the bug after we went to the drive in theatre last fall. This was just after I threw in a \"good used battery\" I had after my Optima screwed up. Needless to say she was not impressed (good thing it wasn't our first date! :lol: )
I think I'm gonna use the odyssey in my 56 also.

Hey Trev,
just be careful of those automotive terminals for the oddysey. Dont over torque them. I personally dont like the flimsy design but you cant help it because its a motorcycle battery.
I was tightening my battery terminal and I tweeked it afterwards and the terminal loosened a tad off the screw in terminals. I was trying to be make sure the terminal was secure without tightening it too much and it got loose some how. I was test driving my car and I saw smoke coming out from the back of my car and the genny/alt dummy light went on. Scared the Sh!! out of me. Took the terminal off the alternator and taped it up with black electrical and crippled her home.
I guess if wanted to go back to a lead acid battery and save some weight compared to a DT75 I'd use a Group 51R or 51 honda battery.

Hey Trevor, we have hills. We can clutch start our cars without pushing.
The Odyssey PC 680 does not have nearly enough CCAs to get your daily driver started when it is -5

Thanks Bruce.

Could the metal jacket on the Odyssey be there to aid heat dissipation? A little battery doing the work of a big one is sure to warm up quick during an extended crank.
As far as a cheap lightweight battery goes I've had some excellent results from the more skookum lawntractor/snowmobile batteries from Wal mart. As long as you maintain the water level they last for 3 years+ and at around $25 they're not a big loss if you do cook one. Auto post terminals will fit on to the lugs if you spread them slightly.
Just don't expect it to run your stereo and lights for three hours at the drive in and start your car after.
-

Doubtful. Steel is not a good heat sink material, and there's no fins. They advertise it as extra protection.
One oddity about the Odyssey is the re-charge rate. If it is fully discharged, it only takes 10 min to completely charge.
-
I've been selling batteries for ten years from Interstate to Delco, Magnacharge and Optima. They all break, they all have defectives and the only thing I have learned is to look for the most popular in the area you drive in, keep your reciept, and test your battery once and a while!
No matter what you drive or where that is the best way to make your life way easier!
(I have seen a optima melt in half and still work! Pretty fricken cool)
-
I know this is an old thread but i think i have a relevant question.
As any batterie that is mounted inside a passenger compartment requires venting. How do we solve this with our under seat mounting in our Beetles. How do we vent our batteries.?? Were the stock group 42 batteries vented with a pipe outside of the car?
Thanks Rene
-
With a sealed battery box and length of poly hose drilled through floor. The one time I went through tech at mission with my old diamond green car the guy mentioned that rule but didn't stop me from racing.
-
Most tech guys at the race track can't read English. The NHRA rule says the battery can't be relocated into the passenger compartment. Our batteries are not relocated, so they are perfectly legal under the back seat.
Stock VWs weren't vented with a tube.
-
I have used an Odyssey back when I raced my dragbike and I have one in my Pro Mod (even though I don't start that one up very often LOL). I have never had a problem with either on them. If you want car posts just order from their car line rather then the motorcycle line of battery. If you want small you need to check out the tiny batteries that come from the factory in the Jap right hand drive cars. They are very small and light weight but are for street cars.

I bought a pc925 after a bunch of reading.....actually started carving out a mount for it last night!!

Milling machines are fun to mess around on even if you have no clue what you're doing?

No. I just spend too much time on the internets.
