Buy a can of Fix-a-flat or join AAA and ditch the spare and jack for a much more significant weight loss.

 

Of course, but why not do both? They both provide significant bang for the buck. There really aren't that many mods that provide more performance benefit per dollar.

 

I had a mini-battery (Odyssey) on my EVO for a year and a half and over 50,000 miles. It worked flawlessly! I would not get one for my Lexus though, thats just me though.

 

not a bad point. Not sure how much the JoeZ pipe is these days, but if you think about it, it's the same HP gained for 109.00 bucks. A combination of a few things could shave off .2x or even some better times around the track..I noticed that oddyssey had another battery up from from the 680 called the 925T. It says it's 24lbs and looks like you could probably use that as an everyday battery?

I agree.

The 925T is a good compromise between lightweight and performance.

 

Thought I would throw this out here in case anyone was wondering. The spare, jack and the small tool kit weighs 36lbs. Combine this with the approximate 35lbs you can save with a lighter battery and now it's like having 4-6 more rwhp for under $100.

 

isnt' that basically what the 550.00 tanabe exhaust provides? hmmm..

so has anyone tried the 925T as a full time battery in any car?

 

The problem with the 925 is that it won't shave much more than probably 10 lbs, and it is probably more than $100. I would do the 680, or stick with the stocker or Optima.

 

roger that. thanks.

 

any idea what the stocker weighs? i wouldnt wasted the money unless it shaved off atleast 20... id like to find one that will work good that could shave off more though

 

I just weighed mine on my bathroom scale at 42.5 lbs.

 

So basically, the PC680MJT would save 26.5 lbs, and the PC925MJT would only save 16.5.

 

16.5 is about what the spare weighs right? If I thought that 925MJT could run my car for normal use I'd get it. I just leave my car sitting there though for weeks at a time, and sometimes even longer.

 

Personally, I think a 925 would be totally fine for a couple weeks. The 925 has a 50% higher CCA compared to the stock battery, and it is effectively a deep cycle. The only way that it doesn't measure up is in total capacity. It only has 28 AH compared to the stocker's 70 AH (when brand new). However, I doubt a 1 year old stock battery that sits for weeks at a time would be anywhere close to 70 AH.

 

well I just might order one then. Thanks for your input greg. I do jam my stereo while in my car but i don't have the ML or anything so that shouldn't matter. 16lbs isn't bad. If it last for a year, i'll be happy.
