What I thought was a weak starter turns out to be a weak battery. I'm not sure if the battery that's in there now is the correct one but I want to buy the biggest battery that will fit. Will a group 49 or group 93 battery fit the Caddy? If not which one? Advance has a coupon code DOTW52 for $40 off off $100 purchases till 12/29.

Measuring tape? Buy one and try it? LoL
I find the biggest issue with changing types, is the posts are in different locations.

I'm wondering the same thing. 850 cca vs 650. nice power difference. The Group 93 battery is wider by about 4 inches
http://www.rtpnet.org/teaa/bcigroup. I need to get a battery for a mk1 scirocco, unfortunately i don't have the car yet to measure if it will fit. Modify the battery tray i guess, would look something like this if you have the stock radiator:

I have the same battery in my MK2 as I do my chevy pickup. 1000 CA 900CCA nEVERSTART MAXX. Big, yellow, and from Walmart *haven't been inside any walmart in over a year now* They fit, but I put a thick piece of cardboard in between it and the rad so the screw doesn't wear into the battery. It is about 5" too wide and hangs over to about the starter, but it sits there.

What model VW is the pic below and what group # battery is it? Anyone else tried fitting a group 93 battery into a Caddy?
edit: My Caddy is not with me and I am trying to order the battery online before the deal ($40 off) expires today.

Wondering the same thing I pulled that picture off the internet (Bing Images)
http://www.alexlockhart.com/rabbit/html/pic27.html , I'm not sure of the actual group number of the battery in the picture, but that is what they look like. I have one in my 85' mercedes diesel. I'm really tempted to get one too, the AZ part states:
Product Application(s):
1985 Mercedes-Benz 300TD
Must use part labeled Part Number 93-1 and Group H8/LN5/49; 825 CCA; OE Group H8; OE CCA Rating: 740
,,, so it's a group 93, 49 , LN5, or H8. Battery posts and dimensions are the same just wider so it will overhang the battery tray which MAY but probably won't be a problem.

You may want to research residual capacity and amp-hours as well as these are particularly important for a diesel. The glowplug cycle draws a lot of current and a gasser battery may not have enough CA after a GP cycle or two. One of the best batteries for an IDI would be an OEM ALH battery. It's large and has the Ah that virtually no aftermarket battery can match. Only downside is it's expensive (usually close to $200 but some dealers sell it as low as $108).

I have a group 65 in my rabbit. Terminals are on the wrong sides though. It works. Quite well.

This is my battery setup in the old flat red bunny and the MK2. Same 1/0 cable, same battery, just a different car. The battery actually fits better in the old 84 than it does in the 86. I think the a/c was the difference. It pretty much equalizes the weight of the engine lol. With 1000CA I never had an issue with cranking speed even if I wanted to glow the plugs 3 times in 0F weather.

I run 1000 cca Optima redtop battery in my Caddy.
Largely because AGM makes no battery corrosion and they last so long.
Additionally, I like the wingnut terminals.

I am not a fan of Optimas. Most that I have encountered need warranteed right as new. Granted they do take care of it, but what a pain.

I have 13 Optimas in use, some for over ten years. Really like the no corrosion feature. As acid batteries fail, I AGM the equipment.
Have lost one; it was 10 years old, still charges up, but droops below 70% overnight with terminals disconnected. Will start a car still, but not dependable. I use it to run my fuel tank pump still.
Thats a pretty good record.
I bought an Oddessy 2250, and sent it back for warranty after 8 months, but started discussion warranty exchange at 5 months, and there was no cold weather involved. The reason I sent it back, was when charging at 13.4V, it boiled acid out of two cells, which is not supposed to happen. I have not had that issue with Optimas.
The biggest problem I have seen with AGM batteries is learning how to charge them or people not understanding how to charge them. I have drained them to zero, put a charger on them and it kicks out saying "bad". Simply disconnect terminals, charge again, repeatedly bringing it back up about 20% each time. Once at 70%, Optimas will charge right up and be a good battery again. Fully drained AGM charge best on digital chargers compatible with AGM vs alternator. Once at 70%, or even at 50% any 12v-14VDC source is good.
Since all my Autos are nearly 20 years or older, as well my tractors, I do not like to replace battery trays, etc.
I have 16 diesel vehicles or diesel equipment to service, and the time saved from cleaning terminals amounts up. Not cleaning terminal in 5 or more years is valuable time saved.
For people who don't keep an auto over 5-8 years, I do not suggest them. For me on my farm, they are great.
