I want to get an optima yellow top battery in the near future. I need to know which I should get, like what model number, since they all seem the same to me. It will just be used for normal things, nothing extravagent. I got rid of my old battery and plan to relocate this one to the trunk, but I'm going to make my own box for it and I need to know what the dimensions of it are first. So any help would be appreciated. Car is a 90 240sx with sr.

 

I think Optimas are over priced and over hyped. I went through 3 red tops in 2 years. I swtiched to a Die hard and havent had an issue since.

 

The yellow top claims to be able to recharge in an hour. All the promises it states are great...any other opinions...I have never heard anything bad about the yellow tops....

 

I have a yellow top in the trunk of the Caddy that I paid $50 for. It's 7 years old and still works fine.

 

This is what I have in my car. I got it at Advance Auto Parts.
Red Top
Part# R34-980
CA 1000
CCA 800

 

I have a red top in my 240... relocated to the trunk and haven't had a problem with it. My car starts up right away even when it sits for 2 or 3 weeks.

 

Oh yeah, I have a 9 year old red top in the Camaro too. Fucker has no problem starting the car even when it sits for 3-4 weeks. I have to crank it a bit too to get gas back up in the carburetor too.

 

ive never had any "special" batteries in any of my cars, and i never really have problems. except one of my cars the e-fans kept coming on overnight killing my battery

 

Optima yellow is a great battery for the price. go for the redtop if you dont mind spending a little more cash

 

OK, ya cash is not a problem so which type of red? like model number since I know there are differnet sizes and such...?
