I was wondering what type of battery i should get for my 7. I was looking into an optima but not sure whether to get a yellow or red top.

I do have a 3000 watt single twelve in the trunk on a 1100 watt amp with a capacitor and i also have a 500 watt amp for all my interior speakers. Plus i have gauges, an in-dash dvd player, and driving lights. I really dont want to spend more than $200.

The reason i need a new battery is the one i have now is an old *** AC Delco and it only has like 500 cold cranking amps and dies in like 2 seconds. My volt gauge doesnt bounce from all the stuff i have right now but i also want that added protection in case i blow my alternator away from home

 

no one has ever used either one of the optima batteries or anything similar?

 

I have a red top in my turbo 2. It works fine. It came with the car when I bought it though so I dunno if I could justify spending another 180 bucks for one

 

well i can get new ones off ebay from a dealer that sells them. I think the red top shipped is is like $139 or something and the yellow top is $189 shipped

 

I've used Optima redtops in my last two cars.
The one in my 240Z was still going strong after 6 years.
Put one in my 7 two years ago and haven't had any problems.

I've read random comments about a decline in quality (I think Aaron Cake has reservations about Optima) but I've been happy with mine.

 

I think that i might just get a red top then. Seing how the the difference in reserve power is only 8 minutes and the yellow top has less cranking apms. Not to mention that even with all the stuff i have in my car the volt gauge doesnt bounce at all with my S5 alternator and every thing is nice and bright too.

 

never used 1 but ive heard that optimas have problems if you dont run them after 1 month or so. buddy of mine had a yellow top explode.

 

ive got a red top and it works fine

 

Yup!

I have one on the Miata and one on the FC. Ever since the FC went "under the knife", the car gets started once a week, and after a while, the battery will loose charge. The optima battery seems to create a "memory" much faster than regular batteries.

The one on the miata, which is used everyday is absolutely amazing!

My suggestion is, if you will use the car on a daily basis (or at least 3 days a week) go for it, otherwise, forget about it!

BTW - I purchased mine trough "autozone" for like $149, and they will replace it on the spot if its under warranty.

 

What you need is an upgraded alternator as well.

My personal choice for a battery is the Deka Intimidator. A few years ago the failure rate of Optimas went through the roof. It seemed that every car I saw with an Optima had a bad battery, including my own.

 

^^^^^Yup.. But i have them in 2 of my vehicles....s10 blazer = winter beater and the rx7.

The blazers battery died twice since i have had the red top in (over 1.5yrs) I recently(4 months ago in january) went out to start my blazer and it was dead...went to autozone and they exchanged it again.....they thought i was scamming them for their shitty product so i now have to pay a sliding scale for optima exchanges.

I started my blazer 2 weeks ago after sitting a while (its part tank so its ok) and it fired right off.
I was actually impressed.

My rx7 has had a slight voltage leak (or the battery was **** since it was given to me) ..the ***** left me stranded at school, so i immediately went to autozone and bought a red top.

It has been fine ever sense.

I am a fan of redtops and their exchange policy, and think their quality is back on track again.

If I'm not mistaken the yellow tops are meant for marine applications such as boats.

 

YT is a deep cycle battery, BT (blue) is a marine battery. RT is a starting battery and what should be used in vehicles.

 

I plan on going to a FD alt or a tempo alternator.

As far as the deka intimidator which one will fit my rx7?

 

Pretty sure there is only one model Intimidator. It is available with various posts though. Get top posts.

thats is where i was looking where did you get yours

 

well got a red top and my dad bought it for me but my staring issues still persist. Even with all the extra **** depowered and removed

 

I purchased mine from the local battery wholesaler. They are a Deka dealer. I believe mine is the 9A78DT.

 

got the red top now (free to me) i will keep them in mind incase this thing ever goes though
