Hey everyone just trying to find out which Optima Battery to buy for my 2005 tC. I currently have one DVD player, iPod, PS2, Whelen 90 watt strobe lights, 400watt power inverter, a eD 9.2x and 9.4 amp. And I will have an Inferno LED underbody from WWW.OZNIUM.COM later next week and want to make sure I have plenty of juice for everything. Anyone know of any Group Buys or where to buy one online for cheap? Also how many of ya'll have any 15" subwoofers from Elemental Designs??? I currently have 2 eu700's which are perfect but looking for something for when them punks pull up next to me and need to be put in their place. JK

 

a yellow-top ought to do ya. I have a feeling that the stock battery would do just fine as well.

one thing on the optimas - NEVER drain one completely. you will never be able to recharge it.

 

I got mine from Costco for cheap... YellowTop are probably going to be a good solution for you.

 

I would say Costco. Before I got my yellowtop I searched for two weeks and Costco was the cheapest.

 

i run kenetik

 

sorry guys but on costco.com i can not find anytype of optima batteries let along car batteries at that. All I see are inverters and stuff.

 

You need to go to an actual Costco. They carry the 75/35, which they sell for about $105. As noted by the little sticky dots, mine dates to my previous car-- I bought the battery in November of '03.

 

Sorry if this is a stupid question....but what is the advantage of this battery?

 

Sorry guys I live in Vero Beach Florida and I just tried searching and there is not a costco within 50 miles from vero. so i guess i'll just have to find somewhere else online that will have em cheap

 

did you try Ebay?

 

I am staying away from ebay for alittle while becuz the last two items i bought i am having major problems with them one was the so called "oem foglights" that were all cut up and modified in the back and was definately not brand new like they said and also i bought an amp from this guy i have bought from b4 with no problem and for some reason one channel stopped working and i sent it back for a replacement and he has had it in his possession since the 9th and he has still not taken care of the problem or informed me of what was going on

 

D34/78 is the model you want for heavy audio/video applications, according to optima themselves... i got mine at sears of all places!

 

Do a search on their website. They were a little scarce when I was looking for my Yellowtop.

ok which battery is it I need becuz I have heard conflicting posts. I have heard like the 75/25 or 75/35 I believe and now SkaTG2k3 says 34/78

 

The 34/78 has 20 minutes more reserve capacity and 90 more cranking amps than the 75/35. Other than the 34/78 being 5lbs heavier and slightly larger, those are the only notable differences.

 

hey, it was cheaper! that what matter to me!

 

So Dr. it sounds to me like you are prescribing me the 34/78? is that correct? Also I know this will not simply fit on the stock battery holder and tie down so what exactly will i need to be looking to get to secure my battery in place? Thanks guys in advance for the help I have never upgraded my battery b4 just a higher output alt. once b4 on my old xplorer.

 

Buy whichever is available local to you. I have the 75/35 because in terms of local carriers, it was about $35 cheaper.

And no, the stock battery tie down won't fit (the optima is shorter and smaller in every dimension). But I know I guy that can sell you a CF one, identical to the one in the pic above. Wink wink.

 

hmmmm... i got mine to fit on the stock holder... (with a little help of a 2mm plastic trim piece)

 

...and how far from the sides of the battery are the tabs on the OEM tie-down? Sure, it fits. But it looks a bit off.
