Question Optima Red Top Group 35 R

As I've accidentally left my dome light on overnight for more than two occasions and have my car jump-started by the owners of my parking garage, I believe that it's about time to replace the stock battery and upgrade to something a bit more reliable. Yes, I realize that it was my absent-mindedness that destroyed my the stocker, but I had considerable problems starting it in near-freezing temperatures.

Being the impulsive guy that I am, I did some research and bought the Optima Redtop G35 R battery from a reputable site (BatteriesRUS.com) and it is shipping as I write. However, I need to know what I need to do to install the battery. Do I have to do anything to the stock battery terminals (IE modify them) or can I use them? What about the battery tie-down? Is it practically a plug-and-play fit, or will this battery require a longer starter cable? Can I do all this myself (I have moderate experience with tools and have done some of my own mods) or is it better to have Autozone help out on the install? I need the battery in before my long journey home so I need to install it ASAP when it gets here.

Thanks in advance!

PS: Yes, I realize this isn't N/A related per se, but I've seen threads on batteries in almost every forum (N/A, 2.0 Turbo, STi, Electrics & Lighting, Car Audio, Service & Maintenance, etc.) and didn't know where to put it. I'm specifically talking about the fitment for the GDA EJ25.

I've heard that one of those batterys has the terminals on the wrong sides, make sure the orientation is correct (positive, and negatives line up).

I always heard that the yellow top was better (better deep cycle capability and all the cca you need). I also read somewhere that Optimas were heavy and there was another battery out there that was a better choice as far as weight savings go; why did you opt for the red top?

Lighter batteries have less CA/CCA, fewer amp hours (AH), and usually require some sort of modification to fit. While the Red Top is comparable to the stock battery in weight, it is much more powerful and will last for far longer. Finally, lighter batteries tend to die out faster and don't work well in cold weather. Because my stock battery had considerable trouble starting my car in colder weather, I decided that the Optima was the best choice for my application.

If it's the "R" type it should be a direct drop-in replacement. The "universal" 35/75 has relocated terminals which require a longer starter cable, but the "R" has the terminals in the stock locations, at the outside corners of the battery. It is not as tall as the OEM batt, but the factory hold-down will still work. As for weight the 35 is within a pound or so of the stock battery's weight, it's the 34's that are several pounds heavier.
I've had a 35 Red for almost two years and it's been a huge improvement over the stock one, especially in the winter. You are doing the right thing.

Any idea on what the installation procedure is for a new battery? I know I have to take off the stock battery clamps and stuff, but I don't know what order I'm supposed to take them off. Also, how do I remove the stock battery-tie so I can remove the stock battery? Is there anything else I'll have to do?

Thanks!

How about the yellow top? Isn't it better than the red top?
I'd really appreciate a link where I can learn more about different types of car battery.

Im using the Orbital "black top" from Exide...you really dont need a deep cycle battery unless you are using it with an exsiting battery.
the red top or any "starting" battery will be fine
with my battery I have left my radio on for over 6 hours playing load and never had the battery die.

Well, my Wallmart battery works great too... Its been in the car for almost 2 years now, it starts the engine in the cold, runs the lights and radio, etc etc etc... The bottom line is that pretty much anything will work. I'll bet if you got 30 rechargeable "D" cells off Radioshack and strung them up 10 in series, 3 banks of 10 each in parallel it would run your starter reliably for years. What I am curious about is what the practical difference is between a red top and a yellow top. The yellow top is deep cycle, the red top supposedly produces more cold cranking amps. But if a wallmart battery produces all the CCA you need, wouldn't it be advantageous to have a battery that can fulfill the CCA requirement AND run deep cycle?

The Optimas use a different construction than your standard Wal-Mart or other lead-acid battery. You can read more about it here-

Die-Hard is same as Wal-Mart, at least in the most common sizes: both brands are made by Johnson Controls. Of course it can change.

I was in the same predicament this past winter; I needed to have my car jump-started two or three times when our New Hampshire winters were hitting like a zillion below zero. (I'm now in PA. But that has nothing to do with the weather. )

I was really shopping for Optima, but honestly I ended up with a Die Hard Gold. Sears now sells Optima batteries, but to be perfectly honest, the Die Hard's warrantee is better. That and if anything ever goes wrong, Sears is everywhere in the known universe, and even though the company now covers Optima, Die Hard is one of their cornerstones. It has like 100 less crank amps than the Optima, but still has about 150 or 200 or something more than the stock one.

And since my OE one lasted 3.5 years, I'd say I'm good to go.

The problem is, I don't know how to do that exactly. I'm afraid of hurting myself via electrocution or battery acid Seriously though, how do I get the battery tie off, how do I remove the post clamps, etc.
