Hey guys

I am planning to go overseas for 3 months. What if I just leave my car in the garage for 3 months will the bettary die when I back? However I am thinking if I disconnected the bettary it will clean the memory of the car, not sure it is harmful or not. Any ideas? :D:)

I would think if you have an alarm that would be the biggest problem in disconnecting the battery. It is recommended if U go away for more than 4 weeks that U disconnect the battery, however, that doesn't stop it from draining as all batteries discharge over time. First, make sure it's filled up fully with distilled water and is fully charged and then store it in a cool place. Then, the best way to maintain the battery would be to buy a battery charger with a trickle charge facility. I used to work at Jaycar Electronics and they sold some really good value for $$$ car battery chargers. However, I'm sure any other product of similar specifications would do the job, not just Jaycar's (i.e. I'm not promoting Jaycar merely because I worked there).

Just an example of one:

That plugs directly into your mains outlet so it shouldn't be a problem.

It won't "clear" your memory, just reset your clock and erase your radio presets so U should be fine

yeah something like that jaycar maintenance charger would be perfect. otherwise just disconnect the battery. if you take it out of the car do not put it on a concrete surface it will discharge quickly and be ruined. if you must put it on the floor at least put a plank of wood or something between it and the concrete.

it won't hurt your car not having a battery for 3 months.

Hahaha, thats the funniest thing I've heard for awhile, you obviously skipped science at school. :P

try it. the cold surface of the concrete will help speed up your batteries discharge. it's not a matter of science it's a matter of practical experience. but if you know better, go put your battery on the concrete floor of your garage for a week or two and tell me how that works out for you.

The cool surface acts a heat sink for the battery which after a period determined by the ambient temperature will slow down the electrochemical reactions in the battery making them appear flat in the short term. Given a bit of time to warm up, they will recover.

And I do have a battery on the concrete in my garage as we speak, always done it, never an issue.

Are you religious?

The materials that modern battery cases are made of are less condusive to leakage (and better sealed) and from a "modern" battery's perspective, I doubt there will be any leakage or acceleration of discharge by leaving it on a concrete floor. The biggest problem is dirt build up whilst on the floor. When dirt builds up across the terminals, it can form an acidic layer which can carbonise the dirt into an electrical conductor of sorts thereby creating a short circuit of sorts across the terminals which subsequently drains the power a lot faster. From working at Jaycar and dealing with a lot of auto-electricians and mechanics, I've also heard (though I've never seen it proved) that thermal gradients can also redude the life of a battery - i.e. if the surface the battery is sitting on is a lot warmer than the ambient temperature around it.

Appreciate for all advices. :( Think I am going to buy a battery charger. By the way, any other issues need to be concerned? such as engine,transmission,oil..etc. Thanks :(:(

Nah mate, they're all sealed up, you'll be fine. Maybe factor in an oil change when you get back.

Enjoy your trip, don't stress about the car :blink: .

      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.
