Optima Red-top

[Phatboy]

Hi guys, looking for a battery that can start my car every time, without going flat if I leave it for a couple of weeks. I've got an amp and 12" subbie but never run them off the battery alone

I've heard good things about the optima batteries - and I guess the red-top would be the one I'm looking for. Which model should I be getting so that it fits in an R34 GTR (boot)?

Thanks

Be sure to save the receipt. I had one go bad and ended up having to get it replaced. It is a really good battery, but I do hear they have some QC issues.

Was strange, when it went bad it simply acted like an open circuit. Wouldn't accept a charge - and actually read Wide open when I checked for resistance. Replacement has been running fine for about 9 months.

My battery is completely f'ed. Im looking for a new battery. Was thinking about getting either the yellow or red top but heard that the yellow top was a lot better but there's so many different types that i don't know which one to get. I drive a 180sx and want to get it boot mounted, any suggestions would be great. I also heard that the yellow top is better if your running full audio, lights .etc

yea yellow top is alot better for stereos and the like.. red top is fine for a normal car.. i think it says on the label that it can play for up to 3 hours without the car being started.. yellow top is longer tho!

I use a yellow top in my R34 GT-T - love it. The car sounded so much more positive on crank-over from cold than compared with the original japanese battery it was imported with ..

ive got a 640ca yellow top in my car and i cant listen to my stereo above half for 15mins before it goes flat. but i can crank my engine for 1.5 hrs before it looses its kick. maybe i just need a BIGGER battery

had a red top on my rx7 for 11 years. never died!!!

but get a yellow top, at least 800cca

and upgrade the terminals and grounds when you do it

every battery can die for no reason. had a optima last a few weeks on a tiny system in my old commo.and dont buy a grey market import battery, they wont cover the warranty here

FYI: if you run them dead they need a "proper amp" charger not a 20 dollar one to recharge it

OK no worries, will go for the 800 cca red-top. I'm using it to crank engines, not really for audio. Thanks.
