What aftermarket Battery Should I Replace OEM with?
 

So I've replaced most of my lights with LED's, have a radar detector, 2 chargers for my phone and iPod, as well as a 500W amp and JL 12 W3 sub. Stock battery is practically dead to the point where I need an external jump every other time. I'm looking for a battery replacement that can provide the car with enough juice! I'm really hoping it's not a problem with the alternator either..but I'm pretty positive it's the battery.

So far I've looked at Interstate and DieHard batteries. If anyone could chime in on the size or type of battery they bought and recommend would love to hear your input! Thanks :)

yeah, stock battery sucks balls :)

Optima yellow top, the biggest size possible will fit, but i opted for the one right under the largest one.

D34/78 is the size I used, you'll have to bend the terminals out a little bit (very little modification tbh for a very high output battery).

I used that and I had to use some adaptors to get it to fit in my car properly (because the battery's smaller than O.E.).

I'd say you can squeeze in a D27F in there if you so desire, a lot more juice for your amp and future needs!

I am using duralast gold, it comes with 6 year warranty and has more capacity then yellow top. You can purchase it in auto zone.

Yellow top is reverse for my car terminal. (GS430) so I use red top.

Yup, this right here.

I just replaced my batter with this too. After doing a some research, it appears Optima's quality has really gone down in recent years, so I went with the duralast gold.

Yeah Optima has really gone down . I think one of the best batteries right now are the Costco brand. They are basically the same as Interstate batteries that are made by Johnson Controls. They have great CCA ratings and the warranty is awesome.
Your car runs off of the alternator when the engine is running. The battery is only there to start the car and to power the car in accessory mode which you won't be using most of the time anyway and even if you did time to time to listen to the stereo or anything, a regualr battery is fine. There is really no reason why you need an optima battery in my opinion.

I would go with this...dont really need to spend the extra dough for the optima.

+7 Duralast Gold in both Lexus and the 4runner

Optima yellow top enough said lol.

Thanks fellas! Just got the Duralast Gold for $110. They wanted $50 to install and I was like wtf no way that's half the price of the battery! I end up doing it myself. But the Asst. manager ended up just helping me installing it for free! :thumbup: Thanks for good look CL fam!

o'rly? I didn't like the duralast gold because it needs to be replaced often (I mean, no complaints but still).

Are you sure worker? I use the Yellow top in my vehicle, 2006 GS430. Like I said, you need to bend the terminals a bit to get them to fit right, but MAN do they perform well :)

Really now?.... I got my Optima battery for $125 after MIR and instant discount. Both ordered throug hthe phone because advanced auto doesn't let you buy what you want, they go by the suggestions :(

+1!!

what ridiculous place charged u? All battery changes at all the local auto parts stores do it for FREE. My guess is you got it from advanced/autozone, right?

No problem man, i also threw out the plastic piece that hugged the oem battery it just wouldn't fit. I have had it for 6 months and i cant oill the battery im all stock but blasting music while car is off didn't last long on my oem while here it lasted for atleast 2 hours.

Haha Autozone. The guy helping me out was a car junkie too, he had an EK and helped me out for free anyway :p

Heh that plastic piece was giving us trouble during installation too. I kept it on though because it a bracket stuck on that held two clips for a certain electrical wire. Good to hear I could blast my music for much longer than stock would allow me!

Duralast gold for me as well, outstanding battery with excellent warranty
