Optima

Do you really think your $150 battery is better than
my $50 battery that lasts 5 years here in Phoenix where
batteries die in 1 or 2 years??

Is the orange top deep cycle or regular? what the difference between the orange and the others

What kind is it? Where is it available?

If you have high draw I have been told they are very good. I have three amps, so I'm pretty hard on them. You think phoenix is hard on batteries, try a chicago winter. What 50 dollar battery do you have?

 

anyone out there using a yellow top. Did you have to mod to put it in.

 

Duralast

Duralast from Auto Zone..

The Heat is far worse for a battery..

Dries the battery out-no charge if its dry..

I know about cold also, but the cold is harder
on your starter than the battery..

A battery is a battery..

unless you are 4 wheeling in the Moab of Utah!!!

how does it dry it out if it's completly sealed??

 

I run a red and a yellow top, with the yellow as my primary. The orange top is the same as the red top, but with the poles reversed. To get the yellow in you need to do 2 mods. 1) you need to lengthen the ground wire that goes from the battery terminal to the fender side wall by about 6 inches or so. EZ to do All the other wires are long enuff. 2) you need to make some kind of platform for it to sit on as it is about 1" shorter than the stock batt. I used 3/4" pvc pipe to make a square and zip tied it to the bottom of the batt. Fits perfect.

Besides having the benefit of a deep cycler, the other advantage going with optima is that the spiral cells are much more resistant to vibrational effects that can shorten the life of plate style batts.

what is the CCA and reserved ratings on the yellow top you have?

 

650 CCA
BCI 120 min at 25 Amp discharge @ 80F to a 10.5V cut-off

 

Try the Optima D31M. 900 CCA, reserve capacity 155 minutes. I've got one and am really impressed. I think it is worth the extra few dollars if you are running a lot of extras.

what color top is it or where do you find it. I have only seen red top, yellow top, and orange top, or do they come in different ratings. Also did you have to mod to put it in??

What is the CCA and reserve requirement/reccomendation of the tundra, any body know?

It is a Blue top that is the same battery as the D31 yellow top with an extra set of top posts for accessories. Requires very little modification to put it in.

Optima D31M

what did you have to do to put it in? same mod as below? aren't the blue top marine batteries?

 

To install the battery I had to 1) elongate the J hook. I did that by simply adding an S hook to the bottom of the J hook. See my photos. 2) Put some rubber cushioning on the stock battery hold down bar and 3) slightly elongate the negative ground, I just put in a new one as it is very short and easy to do.

 

I just found out that Optima no longer makes the orange top, but does make a revered pole red top. Part # 34R

 

I 'm stumped on which one to get and how hard it will be to put in or if it's even worth it over a toyota battery. Guess i'll have to figure it out before winter.

what j hook are you referring to?

I think he is talking about the rear post of the battery tie down

 

Starting to look, as it's almost time to buy.

The toyota battery has 750cca, 165RC

The rC is higher than the best optima, so what advantages does the optima have over the toyota battery.

Also was looking around the battery location under the hood, why do you have to make the neg terminal longer, it looks like it should just go right in, especially if the optima is shorter. Or are we talking the small little ground wire attached to the side of the truck and to the neg terminal and not the neg termional itself?

looking at the d31a optima, 900cca 155 RC. Does this battery charge much easiler than the toyota making it easier on the alt?

any comments, welcome.

The optima uses a gel electrolyte, as well as spiral wound cells. Meaning: No fluid to check, nothing to leak. Spiral wound cells = stronger, more resistant to vibration/heat than the traditional flat plate. My old eclipse used to eat batteries: bad location (near the firewall = lots of heat) plus the sport suspension = dead batteries fast. I dropped in an Optima, and it quit eating batteries.

The ground wire is the issue. It's short enough on the Tundra's that if you don't use the reverse terminals it won't reach. You could just buy the regular Optima and lengthen the ground line as well.

it's really easy to lengthen the ground line, i used a fi-dolla soldering iron from radio shack, a bit of electrical tape, and some beefy stranded line (also from radio shack, another fi-dolla item). you can mod the battery clamp for about a buck fitty using a longer bolt of the same thread as at the front of the battery clamp, with three nuts, and inserted upside down in the hole, then at the back, any random piece of small-diameter pipe about 3/4" to 1" long from the plumbing department dropped over the j-bolt in the back, just make sure youve got a washer thatll cover it so you can put the stock nut back on. a piece of plumber's rubber sits under the battery, i ditched the stock battery tray.

this is how i got my blue-top in, there are some kinda fuzzy photos in my photo section. didnt take long at all.

Sean,

Looking at the Red Optima. Optima states that the Tundra solution is the Red Top 34R, Part # 8003-151. It also needs the G24 Adapter, Part # 242-0018.

This is the Optima recommended solution. Is it the best bet?

unless you have a competition stereo or a winch + a ton of aux lights, yes, that's the one. the yellow & blue tops are deep cycle--though they're all "deep cycle" compared to a regular battery--meant specifically to be completely drained and recharged hundreds of times. the red top is meant for standard duty, i wouldn't worry about yellow/blue tops unless you have a monster of a stereo or a winch.

only get the adapter if it's cheaper than the 3 bucks it costs to adapt the blue top to the stock battery clamp with odds n ends from home depot.

I am trying to determine the model number for the yellow top optima with the 900cca and 155 reserve. They have something like d31t or d31m or d31a something like that. Any one know the model with the type of studs we need for our trucks in the yellow top with the 900cca, not the smaller one.
