AMS sells a small 15lb battery for the ralliart, which shaves 20lbs off the stock battery.... what are the drawbacks to having such a small battery? Shorter lifespan?

This is the link

It says it's not good for high power audio systems, which works for me i just have the base stereo system....

 

Cold weather/winters can be too much for cold cranking. Running your stereo without the car on can drain it quicker. And lifespan will be shortened.

 

i live in maryland where it rarely drops below 10 degrees F in the coldest part of the winter.... is that ok?

 

ive been running the ams mini battery for over a year now and i live in pa. i havent had any issues with this setup and my winters r the same as urs.

 

Well that's good news, I am going to be getting mine soon so I will let u know how it works with a system.

 

ah crappp! maybe i shouldnt get a mini battery....it gets about -25 celcius in the winter...ughh

 

are there any problems with the car cpu detecting a new battery, or this just a simple 5 minute switchout? did you notice the 20lb difference in the car's performance? it's such a small amount not sure it really would....

 

I really dont see the point of AMS's battery kit, seems like a useless purchase if you ask me that could go towards a better mod.

 

If I recall correctly, the mini-battery is needed if you are getting the AMS intake.

 

mini batteries are great. I say go for it. Ive never had any problems with mine. Ive left my radio running for hours without the battery dying on me

 

3 Years of having Buschurs kit on my 9 and no problems at all. Even started right up after a 2 month hibernation waiting for a new turbo.

 

^ doubt that would happen for anyone with a high power system

 

why would you buy a mini battery if your going to add more weight by adding a high power system lol. The point is weight reduction so I doubt anyone with a mini battery kit is going to have a heavy stereo system

 

^^^I do - but I can remove my sub easily when needed. I have damn near killed the battery a couple times but thankfully I haven't yet.

 

I would imagine this would be the main reason for purchasing the battery kit. And as stated before, when installing a system the alternator is more of a concern. Most battery won't last long playing a powerful audio system with the car off, not just the mini.
