Red or Yellow? and What model?

See car spec below:

you can get ither

 

yellow.

model d35. Fits perfectly.

 

Instructions for Yellow Link

 

do you guys really like the optima?..some customer's ask me about them and i've gotten them in the past but they come back with problems. .specially in the winter. .I deal with Interstate batts. .love em and i've had no problems with them EVER!!!. .they even sell GELL style if thats what you like. .

 

My last optima battery i had lasted me 3 years. It was on my previous car then i put it on my z for a couple of months then sold it with my system. It NEVER had one problem. It never hesitated to crank in any type of weather. It was in perfect working order when i sold it too.

I had to buy another one. I just like that fact that it's a deep cycle battery. I abuse the battery sometimes by draining it while the car is not running.

 

I have an Optima Yellow Top on my Lexus its the best battery IF your running alot of electronics.. I have an indash navi and soundsystem installed and the battery performs flawless.

 

My bad Did'nt read ur sig definatly go Yellow Top

 

my 1 year old Optima Yellow top just went bad, and has been iffy from the start... the car sits alot and during 6 months of winter, but I use a battery tender on it when it sits for more than a week at a time. Either way, the yellow topper I have has a bad cell in it already (about 10.2V after charging it), and if I let the battery sit for more than a couple days without any charge on it, it won't even crank... what a POS. I will be replacing it with something different, like a big Interstate Megatron. I am trying to find the largest battery that will fit in the stock opening without any mods now...

 

did you buy it brand new? Because if you did, you can just go in and get another one for FREE. They have free replacement battery since you only had it for a year.

 

yeah, bought it new... but its a little over a year old, like 13-14 months according to the receipt, so I am screwed... the local 4x4 shop won't help me out, and said its up to Optima, and the customer service tech on the phone at Optima yesterday told me it would be prorated now, b/c its older than 1 year.

 

yeah, if the shop you bought it from won't help you out, Optima won't really help. That's their only flaw IMO, the customer service.

I've always been a fan of the Exide Orbital battery. Cheaper that Optima. I've hava few and am deciding between the Orbital or a Braille (just to try something new) for the Z.

Thanks All Great Info!!

 

Does the battery hold a good charge if car is standing for days or weeks?

 

but of course it does sir

usually if you are storing car disonnect the terminals an leave disconneted

guessing 3 months would be safe

 

I am giving up on my yellow top guys, its too unreliable... I don't know if I just got a bad one, but the local garages tell me the battery tests out fine. I had 2 places check it out... the thing jsut won't hold a charge. Everytime I get in my car, it won't even turn over, and I onl;y drive my Z like once a week... its very frustrating and I need soemthign more rleiable. I have had all I can take with this POS yellow top in there now. I may switch to an Interstate Megatron Plus... i have had great luck with those in the past.
