Do not know which model number it is for the tC. Can anyone help please. Thanks. Also know of any good brand terminals?

 

uhm.. they make different model yellow top batteries?

 

yes they do. There are several different sizes available in for each level of battery (red, yellow, or blue).

Have you checked the website for tC application?

 

there isn't anything under scions on the site..

hmm... i only know of the automotive and indutrial yellowtops..

 

yeah i checked the site but no info available. I contacted optima and they gave me a model number to search for, but I've searched everywhere for it and all i've heard was that the model number does not exist.

 

I think WeDriveScions has a Optima Yellowtop (painted black of course)... u should send him a PM and ask him what size/model number he got.

 

i would look into kinetik. beats the living shyt outta optima and doesnt cost that much more.

 

actually i think kinetik is a lot more expensive. i'd rather go with optima

 

the hc800 is the closest to the yellowtop, but it still provides a bit more CCA. it retails for 120 shipped on ebay. the hc1400 will knock out both of those, and can be found for 185 shipped on ebay......how much are you paying for the optima?

 

i never bothered to check ebay both those seem to be some good prices. i can get the yellow top for 125 locally. kinetic recommended that i get the hc2100 battery but thats almost $400 retail! and it weighs 60 pounds!

 

Do yourself a favor and avoid Optima batteries at all costs! There are several other batteries that are MUCH better, including Kinetic, Scosche, Batcap, etc.

What makes you feel you NEED an Optima (or any other) battery?

Have you upgraded your "big 3"? I suggest doing this first.

I'm assuming you're looking at getting or already have a stereo system - with some "big amps". Usually the only thing a larger/upgraded battery will provide is longer engine off system play time.

Most amplifiers have enough internal capacitance to withstand even the most demanding bass tracks, and external caps are only a bandaid fix. Again, upgrading the "big 3" is key, and 99% of the time will cure any head light dimming, etc. Also make sure you've got the proper size positive cable(s) to the amps.

The differences between the Optima Red, Yellow and Blue are the rates at which they can charge/discharge. The Blue Top is the slowest (deep cycle), designed for marine use, and generally not a good idea for cars and/or car audio purposes.

The Yellow top is suggested by Optima as the battery for cars with upgraded stereo systems...BUT, they're wrong! Car stereo systems need to have the ability to draw energy quickly, and these batteries over time will fail due to the constant starting of the engine, and slower ability to accept a charge from the alternator. Add in the demand of the stereo, and you can see how this is making a bad situation worse....

Their Red Top is their most "normal" battery, with the quickest charge/discharge rate they offer. If you're 100% sold on Optima, this would be the only battery I'd consider. Again, look into Kenetic, Scosche, Batcap, etc. I've known too many people in the car audio community that have horror stories of the Optima batteries failing with no warning.

 

agreed^^

what's your system looking like? if they recommend the hc2000 (theres no 2100), then the optima wont even come close to that. you would have to have 3 optimas wired in to get enough power for that. the 2000 simply has no competition from optima. its probably worth every penny that you can find it for. list out your system though
