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

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

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
